This is the best dispensary. They have hands down some of the best flower around, large selection, at great prices, especially if you buy an ounce which you can mix and match strains. They also have a large selection of fairly priced high quality concentrates and edibles. The customer service is great. 5 stars all around.

Ratings and reviews of Good Chemistry - Colfax
Quality Buds- check, Knowledgeable staff- check, Fair pricing- check. This place is literally perfect and my favorite dispensary. I love the staff there by the way.
The product and service is outstanding. Definitely a cut above the rest and prices are competitive. Don't waste time, gas, and money anywhere else.
Awesome place !
The obvious leaders of the industry in every category. Best price, quality, vareity, service, I could go on for days. Mr. Goodchem is always a favorite.
I'm an out of towner but I visited this Dispensary on the last day of my visit. It has a super cool vibe with these giant screens displaying the menu. There were some great strains to choose from and I got the 7 gram sampler deal. The service definitely wasn't bad, but my budtender seemed a little disinterested and didn't offer much insight on the strains he was suggesting. The mood of the staff seemed less energetic and happy as most other places. But still it was a nice place to buy bud.
Very friendly staff who took the extra time to explain things and when they didn’t have an answer didn’t hesitate to look it up. Clean and modern atmosphere but still felt homey.
Cool spot liked the plant breakdowns.
Such a great shop. Everyone was very helpful and kind. It was my first time and it won't be my last. Meghan really helped us decide what to buy and took plenty of time explaining everything.
Love it! Great quality, customer service, and fair prices!
When I walked in, I felt like I was in a different world... lost... but the staff there did an excellent job of making me feel at ease and getting me exactly what I needed! Awesome saauuuuce! I can't wait to go back!!!
As a tourist, I only got the chance to visit a couple of dispensaries, but Good Chem was by far my favorite. The prices are unbeatable within Denver. The first time my budtender was knowledgeable, friendly, and made buying a great experience. I have depression & anxiety and my budtender had multiple recommendations which so far have been great. Another time I had someone who I think was new but apparently they have a database of what strains are good for what, so she was still able to be helpful.
Very high quality product. As a local consumer I can tell you they have excellent concentrates.
Either this place is understaffed or they don't have any consideration for their customer's time. Stood outside for 15 minutes then waited in the lobby for another 7 minutes. Finally get inside and after waiting another 10 minutes I finally just gave up. Oh and got scolded like a little child for checking a text during the never ending wait. There's far too many options in town to have to deal with one that isn't respectful of it's guests time
Was sold a cartridge that did not fit my pen. Had to come back to store to buy another pen to fit cartridge ~ not happy about that.
Best flower I've found in Denver and fair prices. Awesome staff, great atmosphere. This is my go to dispensary. Love you.
As a tourist, I went to 4 dispensaries in the immediate vicinity & this one was far & away the best one. Best store, friendliest employees & lowest prices. Very classy & clean operation.
I've managed to get street parking I have a credit union and when I use their ATM it only charges me 50 cents. So far everything they sell has been my favorite And oh they have Ingrid.
What else can I say about good chem but wow!!! Budtenders were awesome and extremely knowledgeable!!! The deals on pre-rolls and mini packs is by far the best in town!!! Plus the wife and I picked up some of a flower that they had literally just put out called PURPLE MAYHEM and boy oh boy it is by far the prettiest flower I've ever seen!!!!!
very friendly and knowledgeable staff, good selection, fair prices.
Good Chemistry is a bit of a hole-in-the-wall place, hard to find if you are just driving down Colfax - turn your head to look up at the Cathedral, and you'll probably miss it. But when you do find it, what wonders are in store! The location is somewhat small and cramped, with a classic row of old theatre seats to sit on in the closet-sized the waiting area. Once you are let into the main room, again tiny, it reminds one of a very small cramped pub or bar, with room for about 10 people, standing-room-only. But once you get past that, the flower and staff are wonderful here! The pricing is also lower than comparable quality dispensaries in the downtown central business district. Some charge upwards of $60 for a 1/8th; Good Chemistry is leading the price wars at $35/8th plus tax (walk out the door for under $40). Their selection is somewhat more limited than some of the other places, but often they often have about 10 strains on sale for recreational. Their edibles selection is also top notch, and reasonably priced. Ah, how I miss the 100mg chocolate bites for $12.. If only I qualified for a medical card, I'd go for edibles more often as they are often very expensive otherwise. In short: small shop, great bud, exceptional staff! Well worth the 5 minute walk from the 16th street mall!
love this place best green best bud tenders won't even go anywhere else since finding them
The service and atmosphere of this dispensary has suffered over the years. It is no longer my choice of a medical dispensary. The last time I went, I waited almost an hour to get my stuff. The prices used to be competitive, now they compete for tourists. A good dispensary if you're a recreational user, but they forgot about their bread and butter, the medical user. Haven't been back here in ages.
Staff was super helpful and friendly. Plenty of flower and concentrate available. Seems like a good "first time" place for newbs. The Sour Lemon OG live sugar is amazing!
