What are cannabis terpenes and what do they do?

There’s something about the aroma of cannabis that soothes the mind and body. Whether it’s the sweet fruity taste of Pineapple Trainwreck or that skunky smell that bursts from a cracked bud of Sour Diesel, we know there’s something going on under their complex and flavorful bouquets.

Terpenes are what you smell, and knowing what they are will deepen your appreciation of cannabis.

What are cannabis terpenes?

Secreted in the same glands that produce cannabinoids like THC and CBD, terpenes are aromatic oils that color cannabis varieties with distinctive flavors like citrus, berry, mint, and pine.

Terpenes may play a key role in differentiating the effects of various cannabis strains. Some terpenes might promote relaxation and stress-relief, while others potentially promote focus and acuity.

Not unlike other strong-smelling plants and flowers, the development of terpenes in cannabis began for adaptive purposes: to repel predators and lure pollinators. There are many factors that influence a plant’s development of terpenes, including climate, weather, age and maturation, fertilizers, soil type, and even the time of day.

Over 100 different terpenes have been identified in the cannabis plant, and every strain tends toward a unique terpene type and composition. In other words, a strain like Cheese and its descendants will likely have a discernible cheese-like smell, and Blueberry offspring often inherit the smell of berries.

Terpenes may also play a key role in differentiating the effects of various cannabis strains, but more studies are needed to understand how and to what extent.

Some terpenes might promote relaxation and stress-relief, while others potentially promote focus and acuity. Myrcene, for example, is found in many relaxing cannabis strains like Blue Dream and Granddaddy Purple. Terpinolene is commonly found in uplifting, active strains like Jack Herer and Ghost Train Haze.

The effect profile of any given terpene may change in the presence of other compounds in a phenomenon known as the entourage effect. More research is needed to understand each terpene’s effect when used in harmony with others.

Their differences can be subtle, but terpenes can add great depth to the horticultural art and connoisseurship of cannabis. They may also add therapeutic value to cannabis, based on their unique medicinal properties.

Many cannabis analysis labs now test terpene content, so you may have a better idea of what effects a strain might produce. With their unlimited combinations of potential synergistic effects, terpenes will certainly open up new scientific and medical terrains for cannabis research.

Exploring cannabis terpenes on Leafly

Leafly’s Cannabis Guide provides a visual system for understanding terpenes in the context of each strain. Using data from lab partners, Leafly can help you determine the average terpene profile of many popular cannabis strains—and our list is ever-growing.

Common cannabis terpenes are represented by different colors, which you can explore in this guide. Some terpenes are more common than others, and some tend to appear in higher abundance on average. For example, most commercial cannabis strains are myrcene dominant, meaning the most abundant terpene in their chemical profile is myrcene. You may also find strains that are dominant in caryophyllene, limonene, terpinolene, and—in rare instances—pinene.

The five most common terpenes in the Cannabis Guide, their flavors, and other fruits and herbs they are found in; calm-energizing data is aggregated from Leafly reviews.

When browsing strains on Leafly, pay close attention to the colors of strains you like and don’t like. If you prefer myrcene-dominant strains because they tend to help you relax, look for strains that contain the blue color. And let’s say you’ve had negative experiences with caryophyllene-dominant strains like Original Glue and GSC; you’d want to avoid strains with the color fuchsia.

The 10 Commandments of Terpene Preservation

Adrian Medina

I’ve recently quit smoking and switched to vaping as I know I’m wasting a lot of money burning up my thc. It is clear that vaping is healthier and more efficient and I can consume less and achieve the same high, however I recently got into using terepenes in my bud, like adding essential oils to my Vape or finding that special mango flavored weed.

I notice without the terpenes the high is less and crappy.

I notice with that I’m way more chill and less anxious.

However reading online and in this article don’t these terpenes do most of marijuanas job alone without the cannabinoids??

I know they won’t get rid of pain but it seems to do everything else THC and CBD can do. I will be doing my own experiments but I’m curious as to what anyone out there knows about this??

I know aromatherapy has been used for many years and is proven to work, and I’m first hand experience as soon as I open those essential oil bottles I have had lying around for months, it made me very chill. Accidentally had a drop on my finger and decided to eat it lol, bad idea it burned. Had some honey and that was fixed. Put some on my pillow, bed and recliner and my room smells so dank of lemons it’s very relaxing and makes it easy to breathe.

Also put it in my Vape (only use DISTILLED PURE essential oils as they contain no chemicals or lipids). It’s vaping amazing, tastes great and requires very few drops. 3-5 per 15 ml or so. As far if anyone’s wondering on the safety of this, it is, I’ve heard people doing it for over a year and no problems, no fires, no explosions, and definitely no health issues, in fact reports of better lungs and better quality of life.

Onwards to my real question tho

Can terpenes/aromatherapy be an effective alternative to Cannabis if I don’t want to use it for pain relief and just want the stress free happy feeling that can be made to put me to sleep? I mean it even says anti bacterial, anti fungal, and anti cancer. lol. I have all these terpenes available in my essential oil blends so I’m like I don’t need the pain relief as I’m ok and it won’t save me hundreds more than just switching to vaping, which saved me thousands no kidding.

I probably will continue using Marijuana for its medicinal benefits but now I’m learning that even limonene can give you a psychedelic trip, and we make our own cannabinoids so I’m left thinking. Wtf was weed for again?

Lol it’s not like I didn’t know there were alternatives, I just didn’t think it would be this easy, OR that I had it lying around in my house lmao. I bought these essential oils way back to make water topical that I can use, which is fail don’t do it. Tried in the Vape but put too much and the Vape e juice was garbage leftovers mixed together. So no don’t do that either. Altho it made crap into okay Vape.

Being that I knew there were alternatives I didn’t think of aromatherapy. I was thinking more on the lines of other herbs like valerian which I had no success with, it works to numb pain and put you to sleep but I was very anxious and irritated due to the crazy tripping it makes you do. Also tastes HORRIBLE. Tried vitamin supplements only to hurt my liver….. And then tried eating healthier only to learn fat and sugar and caffeine makes me relax lmao.

So I tried other things because weed was too expensive for me, but it was no where near the same. And I ain’t curing cancer with some b vitamins and valerian. Lol

So to learn all this from you guys and online is a shock there is alternatives.

Am I reading the article wrong tho? Are you saying these terpenes do this on its own or in conjunction with the cannabinoids from marijuana?

Sorry for the rant 😛
- Bailey Rahn
  
  Hey Adrian! So terpenes do offer medicinal attributes on their own, but studies have shown that they do work synergistically with cannabinoids. This is a fantastic read from Dr. Ethan Russo on cannabis terpenes, and I’m sure it will answer a lot of your questions if you haven’t seen this already: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3165946/
  
  Cannabinoids, however, play a vital role in the therapeutic properties of cannabis — they’re capable of functions terpenes cannot possibly perform due to the system of receptors they bind to. If you haven’t read much on the endocannabinoid system (ECS) yet, I definitely recommend doing so. It’ll help you understand just how unique and beneficial cannabinoids can be, especially for patients with particular chemical deficiencies: https://www.leafly.com/news/cannabis-101/cannabinoids-101-what-makes-cannabis-medicine/
  
  But you’re totally right — cannabis products lacking terpenes aren’t the same at all! I’ve noticed this personally with concentrates that strip out almost everything but the THC. The two types of compounds work together in really incredible ways, and it’s so exciting to see new products and technologies coming out that harness the power of those synergies. 🙂
  - Adrian Medina
    
    Thanks Bailey! That was a good long in depth read with many sources lmao, so I feel secure that the knowledge I just gained was in fact truthful and well researched. Thanks for that. I will continue my experiment and vlog about it on YouTube, feel free to check out my YouTube, the channel is my name. I definitely won’t smoke anymore as I just smoked 2 grams of hash to the face and I feel nothing unfortunately but as soon as I hit the terpenes in my Vape I was uplifted and invigorated, much like they describe cannabis is supposed to do. It did have the same terpenes but not dank like my Vape lol.
    - Melissa Rustemov Lohr
      
      Adrian, it’s possible that you don’t feel anything from THC because your CB1 receptor is overwhelmed. Cut back on the weed and just focus on terps so that your CB1 receptor can process what it has stored up.

    thanks for ncbi, one favorite go to o many other maters. I still wiki for the cliffnote versions and links when doing intro or need a refresh on details.
    
    Are cannabis terpenoids actually relevant to the effects of cannabis? Terpenoid components in concentrations above 0.05% are considered of pharmacological interest (Adams and Taylor, 2010). Animal studies are certainly supportive (Buchbauer et al., 1993). Mice exposed to terpenoid odours inhaled from ambient air for 1 h demonstrated profound effects on activity levels, suggesting a direct pharmacological effect on the brain, even at extremely low serum concentrations (examples: linalool with 73% reduction in motility at 4.22 ng·mL−1, pinene 13.77% increase at trace concentration, terpineol 45% reduction at 4.7 ng·mL−1). These levels are comparable to those of THC measured in humans receiving cannabis extracts yielding therapeutic effects in pain, or symptoms of multiple sclerosis in various randomized controlled trials (RCTs) (Russo, 2006; Huestis, 2007). Positive effects at undetectable serum concentrations with orange terpenes (primarily limonene, 35.25% increase in mouse activity), could be explainable on the basis of rapid redistribution and concentration in lipophilic cerebral structures. A similar rationale pertains to human studies (Komori et al., 1995), subsequently discussed. Limonene is highly bioavailable with 70% human pulmonary uptake (Falk-Filipsson et al., 1993), and a figure of 60% for pinene with rapid metabolism or redistribution (Falk et al., 1990). Ingestion and percutaneous absorption is also well documented in humans (Jäger et al., 1992): 1500 mg of lavender EO with 24.7% linalool (total 372 mg) was massaged into the skin of a 60 kg man for 10 min, resulting in a peak plasma concentration of 100 ng·mL−1 at 19 min, and a half-life of 13.76 min in serum (Jäger et al., 1992). EO mixtures (including limonene and pinene) also increase permeation of estradiol through mouse skin (Monti et al., 2002).

  Adrian Madina………Which flavor made the room smell like lemons? Would an essn’t oil do the same?
  - Adrian Medina
    
    LOL yes that’s what I was trying to say maybe I was too vague but yes I put the essential straight onto the pillow and other areas of the room and it was very pungent and relaxing and put me to sleep with clear breathing. I use it inside my Vape a well with great success and I’m breathing easier. It’s also a great flavor. Not to mention its actual medicine in a Vape now other than marijuana lol. Not expecting to cure cancer here but it’s definitely a help.
    
    And I also must add I found out that these lemon scents can help with pain as well so idk it does it all -_- just might not be a good cancer cure like weed is. But I’m cancer free…I hope lol.
    - Tammie Jo Barber-wells
      
      Am I understanding you correctly. You use essential oils in your Vape? I have been using CBD oil in mine and wondered about essential oils.
      - Adrian Medina
        
        Yes
  - waltinseattle
    
    humans have very basic noses. smells like is hardly works like. of course there is some reason for the similarity. just not6 identical.however limonene i just read, and came back to correct myself is the most widely spread of these, the same as in…lemon. linalool is in cilantro…see baily’s ncbi link below!
  - Mark Skinner
    
    So what if it does…..getting relief from what ails you (even boredom) is what it’s all about.
  - waltinseattle
    
    lemonene os lemonene regardless the plant.
  - Gabe B
    
    Terpenes are a major part of what give essential oils their properties.
- waltinseattle
  
  terpenes and the long fatty acids that work to make the total experience do affect with no thc cbd, just moire subtly. I wish we could differentiate which neurons were targeted by various ones, and exactly what else was involved at that particular site. Yes, we make our own, thats the reason we are succeptable to the plant. and btw, we, and higher vertibrates like bovine class that was the discovery point… also make in our own cells… morphine and codine and 6-AM (a monoacetyl morpherne as opposed to the diacetlylmorphene/heroin to work in the same system that uses dynorphan etc. Anybody got a book on terpenoids in asteracea for instance? many medical effects there as pain, inflamation. I wonder if we wont get to a composite formulation once we learn more. my acupuncture herbal doc gave me peony for a bone med.
  - Mark Skinner
    
    In a short time, genetic sequencing will be used to sort out what dope is going to have these effects on these people…..and then we will also be able to accurately predict what is going to happen when you smoke this substance, how it will be different with a different strain…..what “they” will be able to indicate will be complete knowledge of our own body and what will happen and when.
    - waltinseattle
      
      not too short because even when we know the direct effect, we will be clueless to the mix of downstream consequences. Just as with genes, there are cascade effects. For instance if a terpene of other “minor compppound actson the receptor directly, sets it up to accept the canabinoid easier, or if iit affects another chemical that allows faster release fo canabinoids from our system, does a feedback to that generative chemistry, or act to block inflamatory sites quite coincidentally related to the canabinoid primary site. Remember these are cell wall sites, not synaptic cleffs.
      
      of special interest to me is that cbd makes bones mend faster, and stronger than before! so far the rabbit of rat only used, and in Israel. delivery to the break zone is a bit complicated in human use. Having several broke backs I am interested in repair. What signalling could be used to act as beacon tor the cbd, just like other wound chemicals are beacon le to infections , cut etc. As far as I have read the cbd route does not have the problem other hormonal growth interventives have.. growth/repaitr becomes malignancy. Its all the same except for the turn off now, enough whoa, stop already…instead of a simple stop.
- Mark Skinner
  
  Don’t apologise for providing detail. A great read….
- Shane Colunga
  
  the ultimate answer to your ? is no aroma therapy alone will not ease any of your suffering alone. terps are a booster if you must think this way, kind of like chasing a shot of whiskey w/your favorite brewsky. doesn’t do as much w/out the whiskey but can give you a very small minuscule amount of relief, but together they make a power house. hope that makes your ? clear as mud yes?
Shawn D. Wagenseller

We have been testing our strains for terpenes for years and when we concentrate our cannabis, maintaining high terpene profiles are the goal. For example: WA Bud Co Sky Master has a whopping 27mg terp value with Limonene as the dominant terp in the flower. In the concentrate the value rockets to 52mg terps showing a-Pinene as the overwhelming dominant terp.
Our Blackberry shows a 19mg value in flower with Camphen as the dominant, yet in oil the Myrcene becomes dominant.
The high CBD Harlequin is the star in the flower room for aroma with a-Pinene as the2 dominant terp. We have yet to test the concentrate and I am so curious how that will test since it tastes amazing as a dab.
So much to learn about this amazing plant and how it effects people differently! I predict the market will eventually turn to terpene profiles vs just THC numbers as a major deciding factor into which bud to buy and enjoy. The high THC mania is rediculous when the conversation does not include termenes, IMHO.
- Annie
  
  That all sounds pretty damn amazing. And I agree with the high THC mania, I wonder when people will realize that high THC is NOT the most important factor. There really isn’t just one factor that makes cannabis so amazing, every element of the plant work together to create something that can never be truly synthesized or copied.
  - waltinseattle
    
    for years I felt I had to apologize/defend my enjoyment of low thc weed. Like I was a light weight. Soon proven wrong if you brought out some hash! Anyway. I liked the next dday feel of it just aws well as the rush from the night before and gone often lingered. I used pot for energy after a half day of miserable weather outdoor labor. Not energy like a stimulant as much as the loosening of the muscles and letting the lymph through to keep going sort of energy flow. then sleep like a baby and wake refreshed. I never understood the chistry, but I knew what my body told me.
- Farrell Timlake
  
  Glad someone out there “gets it” where terps are concerned. Terpenes can make all the difference in the way the cannibinoids bind to the receptors in the brain. THC is not the be all end all and if that becomes the only thing producers care about then we are going to end up with cannabis following the path of tomatoes, radishes, and melons to become tasteless and lacking nutritional and medicinal value. When someone recognizes that a “20% THC” strain was way more potent than that “39%” that is because he or she is experiencing the way the terpenes helped the cannibinoids.

    I am not a toner but I am researching cannibus as they are making it more and more difficult to get my pain meds. I really hate the side effects of opiates on my body as I get older, I need something to combat sever nerve pain and in my research I have found that maybe cannibus can help my stomach problems and gallstones. I hate the thought of have my gallbladder being removed as that will cause side effects with my type 1 diabetis which I don’t need. The only thing is, I don’t want to be laid out for the day due to being high, I remember being a toner in high school and gave it up because of how it left me. Any recommendations out there? Do I smoke, take drops, vape or use any one of the many other forms of this stuff?
    - Soft_Turkeys
      
      Sorry to hear about your pain and uncomfortable side effects you are experiencing. I know this was a while ago but I saw no one replied, If you are still looking for MMJ advise I would definitely recommend some kind of topical product, perhaps a balm or oil. That will help centralize your pain relief and shouldn’t leave you feeling “stoned”. Hope this helps
    - Shane Colunga
      
      Blue Venow, Berry White,White Bery& Blue Widow will be your new meds for nerve pain, spasms, and inflammation, all without putting you to sleep they are indica dominant hybrids, they grow like sativas, effects to the body like indicas, with cerebral effects like sativas. Happy Blazing:) just a lil pinch will do, like in cooking a pinch of salt same idea here.

  just like fine scotch, wine, or beer:)

  I ask for the terp profiles now at my local dispensaries! It’s amazing how much I’ve learned just living in a rec state for the last year.

This is a good read – thanks Bailey! However, there is at one error: “the development of terpenes in cannabis began for adaptive purposes: to repel predators and lure pollinators”. Cannabis and other related species are wind-pollinated so they do not have any pollinators that can be lured. Terpenes may function as pollinator attractants in other species, but definitely not in Cannabis!
- Mark Skinner
  
  You are talking about evolutionary tricks that Nature brought on hundreds of millions of years ago. We don’t know that wind pollination has always been the go for canna…….
  - Robin van Velzen
    
    Hi Mark, Cannabis are wind pollinated. Their closest relatives, hop, are also wind pollinated. All other species in the cannabis family (mostly tropical trees) are wind pollinated. So it is pretty safe to assume that cannabis has always relied on wind for pollination.
    And even if you maintain that one cannot know for sure what happened in the past it would be inappropriate to claim that terpenes in cannabis developed with the purpose to attract pollinators.
    
    I am not trying to bash anyone here. I am just pointing out one small error in an otherwise great resource!
    - Mark Skinner
      
      You have convinced me.
- Shane Colunga
  
  they have a built in bug repellant, so they wouldn’t attract pollinators they would deter them, this is one of the first things a great grower will teaches you. I cant stress enough the need to get to know your local grower, (but like applying for a job get his/her resume, before accepting any buds from them)( and offer your signature or body for free to sign petitions and vote at city council meeting show them you care and they will return the same to you, I know mine does;) these plants are pollinated by wind hence the need to remove males from your garden to prevent a wasted crop.

this was the best interpretation of terpenes I’ve seen, that we ALL can understand, without getting to scientific for those that just want the basic knowledge to pass along. Thank you for your GREAT article Leafly. You guys rock!

  I’ll second that motion.

Hi there,

Is there a difference between hydroponic v naturally grown cannabis? Is one better than the other for medicinal purposes?
- Mark Skinner
  
  I believe so. Hydroponic canna is grown with chemical fertilisers and I believe that outdoor stuff grown with natural organic fertilisers are far better. But that’s me. Others may think I am full of shit…..
  - Angelo Castiglione
    
    Thanks Mark I appreciate your insight!
  - jrogersp
    
    I disagree!!! We grow hydrroponic food and we do not use any chemicals or man made fertilizer.
    - Shane Colunga
      
      but on one hand one could say I don’t know you how can I believe your not one of the impatient. not to be a turd but most people in todays society are not honest w/strangers not like they are w/family or the same way you are / friends and if you say that its not true you’re living in fantasyland and id like tickets for the train ride there. Hydro is terribad on my nerves, I get the pounds, soil grown can be as high as 19%thc(white widow bc grower), and after the third puff they start.( so for fibro patients w/my symptoms hydro is bad, on the other hand soil grown I cant smoke enough before the sandman comes around , but never any pounding of the nerves. indica lets me sleep but sativa puts me to sleep if that makes sense, could be why white widow and I get along so well.
  - Dylan Brown
    
    One can grow hydro and only use organic fertilizers. I do agree that flushing is important, but that goes for either OD or ID. Most of the nutrients plants need are not good for humans to inhale regardless of whether they are organic or not, so it’s good to flush either way.
- Mark Skinner
  
  I believe that plants are meant to grow in dirt and be fertilised with organic stuff that rots. However I am open to partaking of hydro grown AS LONG AS IT HAS BEEN FLUSHED FOR A WEEK OR MORE. And I would not smoke it regularly…..just now and then.
  - Angelo Castiglione
    
    Thanks again Mark. What does “flushed” mean?
    - Mark Skinner
      
      When someone is growing hydro it means using various chemicals that are not organic. If plants are NOT flushed they will still be full of chemical fertilizers. These chemicals, if smoked will give you one hell of a headache and a considerable amount of nausea. The way to avoid this is to flush out the chemicals in the plant . The way to do this is to give your plants a break from chemicals by only giving them water w/out fertilizers for the last week or more. But many growers are too bloody impatient to wait that extra week or too uneducated to know what they are doing.
      - Angelo Castiglione
        
        Ok, thanks for that Mark!
      - Lala
        
        You mean like water? Nitrogen? Phosphorous? The basic chemicals that a plant would take out of the Earth? It’s like being afraid of MSG, and eating celery, or cooking with garlic and onions.

        I have found the learning curve to be two to three years

  It seems counterintuitive but I have read and have experienced that indoor grown with hydroponics creates cannabis that is superior in treating my chronic illness and pain. I’ve never experienced bad effects from hydroponically grown pot as others are mentioning here and it seems perfectly healthy for me. Over the years I’ve been comparing the effects with organic sungrown, and so far, no sungrown strain can compete with indoor grown for helping with my chronic pain and illness symptoms.
  
  Dominant indicas with a high THC count are the best for pain and illness for me as well. I need the couch-lock kind, unfortunately, although I do alternate with hybrid sativas when my symptoms aren’t as intense so I can have more energy for daily tasks of living.
  
  I am very sensitive and yet have never had bad effects from smoking flower alone. For concentrates (when treating extreme pain), I have to use either water hash, which is very hard to find now, or rosin. All the other concentrates the stores sell nowadays are made with harsh chemicals which tear my lungs up.

    Thanks for sharing your experience!

  I have noticed in areas where its still illegal the Hydro these idiots are buying is a minimum or 3 weeks premature if not 4 they are harvesting right after it gains its extreme odor rather than waiting until it is all sticky & beautiful silly children don’t know what they do LOL I used to have a 20 something friend come buy & smoke mine with me & He said one day I don’t get it I smoke a lot of Hydro upstairs & I come down here & I get so wasted off 1/4 a joint I explained about plant maturity to the kid & He was no LOL as I said they don’t know shit & their dealers growing that stuff are dumber than dirt or they wouldn’t harvest it that soon. I may actually be Badmouthing Dirt speaking of them & these morons in the same sentence LOL

I’ve just started using Cannabis oil for neuropathic Pain. My first order was in the Yellow Spectrum with a very low THC & higher CBD. I really want to get off the opioids I’ve been using & expect that I’ll need to use a higher THC product to do this. The oil I’m considering now is in the Blue Spectrum. There is a note that “Terpenes have been removed”, why would they remove the terpenes? Is it to remove the taste?
- K_Line
  
  Hi – I have a lot of experience with the Spectrum oils – esp. the blue and the yellow. My biggest issue with Spectrum (formerly Mettrum) is that they remove the terpenes. MedReleaf maintains the terpenes in its oils but they are MUCH more expensive as a result because, I understand, it’s difficult to retain them during the extraction process. Both the blue and yellow oils are very good products at an unbeatable price point but I also use the MedReleaf oils because those terpenes make a difference. The terpene-inclusive oils taste much better than Spectrum’s (which still taste, it’s just more of a dirt-like flavour than a herbacious one). BTW, the MedReleaf oils are more targeted than other brands I’ve come across (there are more strains, not quite as binary as the Spectrum oils) and they are of a much stronger concentration (1 bottle of MedReleaf is worth 10 g vs the 5 g of prescription value used by the Spectrum oils for more or less the same volume of oil). I think for someone looking to reduce opioid use, you may want to look into MedReleaf too.

Hi! What is the best resource for reading up on the full list of the 100 terpenes and their benefits? Is there a recommended book?

Did I miss it? All this talk about cannabis terpenes and not one mention of cannabis’ Most Powerful aroma that mimics GRAPE. I know my cannabis plants as trimmer for many years and every once in a while I’d would be trimming a plant that had a powerful grape aroma. I grew one of these grape aroma plants and I’ve Never smelled any other cannabis plant to match it’s aroma strength. Why isn’t anyone reporting Grape smell cannabis plants here?

  idk that is a big one, but grapes themselves don’t have a lot of scent to them. the juice or maybe the insides probably have more of a smell but I always kinda thought this smell in cannabis to mimic what we know to be “Grape” flavor(aka artificial grape) which has a lot more of a scent to it. It could be a mixture of terps and the actual bud creating the scent. good catch tho, hopefully someone knows more than myself.

I can’t but help to enjoy a good series of tokes from vaping. Cannabis should be our first choice for medicine, pain, anxiety etc

Terpenes are essential oils that enhance your being high from cannabis and hold numerous medical benefits. It is said that terpenes “could produce synergy with respect to treatment of pain, inflammation, depression, anxiety, addiction, epilepsy, cancer, fungal and bacterial infections. So, it is important to identify terpenes and how it can affect you.

Hello all.
I don’t much about cbd but would like to get input of what can be used to increase dopamine with CBD?
I have a friend that has parkinson and trying to find ways to help.
Thank you.

Do all marijuana terpenes contain thc? And is it possible to get a terpine with the same effects has marijuana but without THC? I ask because I get random drug tested at work, but would like to use marijuana to help me sleep.

If the weed you’re smoking leaves a large ash that refuses to burn off then it wasn’t flushed.
Most weed leaves a small layer of ashes.
But unflushed weed leaves the entire bud, still retaining it’s form, as ash. You’ll know when it happens.
Some of the medical cannabis I use isn’t properly flushed.

Came a cross rolling paper infused with terpenes named – cannaboost – worth a try or ten

  David is using copy paste at every “best rolling papers” article. Who are you working for David?
  
  Cannaboost is a fail. They won’t even answer about the ingredients let alone an explanation how they stabilize such volatile thing like terpenes. There is a difference between slapping a toxic fixative on top of terpenes and stabilizing the terpenes. Check their poor patent application.

    I used a terpene infused hemp wrap…I think it was called canna wraps…anyway, do not recommend. Didn’t say what was in it and I didn’t like the wrap.

Will a curtain smell from a plant determine the overall out come and quality of it through the terpenes profile more pungent plants would this mean stronger smoke more citrus more uplifting thanks leafy

  Is it physical pain, or pain buried deep within your heart?

  Your curtains will get a certain smell, when you smoke indoors.

Listen guys, I’ve been involved with marijuana for a long time. Growing, medicating myself and others. I suffer from seizures, severe anxiety and PTSD.
I do not get the relief I need from just high THC. I need to combine it with some CBD and I implore you to do the same. Please trust me. Try it at least once. You will feel the same. Like most everyone growing at that time, it was not economically viable to grow low-THC strains so we grew what the people wanted not what they needed. Now with this long overdue revolution CBD is readily available. Be careful though, their are alot of unscrupulous people trying to make money so know your source. Dispensaries always offer great vape cartridges with anything from 30%THC-35%CBD down to 75%CB-2%THC.

Why are the terpenes in marijuana any different or more useful than those in the other plants that are referenced for each different one? Does pot have more terpenes than basil or lavender? The article does not describe why terpenes from pot are unique or valuable. It seems that every terpene listed here has many other sources.

Good article !
Thanks for the detailed information about terpenes .

I was doing research on cannabis and it’s medical use.

The article at Source : https://emeraldhealth.ca/en/blog/beginners-guide-to-cannabis gave me a basic understanding of cannabis and its compounds.
