Cannatonic is a very unique strain, from my experience. I usually smoke THC dominant bud, whether it be a heavy Indica or a daytime Sativa. This is true medicinal marijuana, though. Cannatonic has very little psychoactive effect. For some, that is a negative, but for some it is a major and strain defining positive.
This certainly isn't recreational weed. It isn't going to get you stoned or high. This is just pure good stuff with true medicinal effects. About 5-10 minutes after smoking, the effect starts to set in. A very nice, broad body buzz, all pain melts away, physical, emotional, and mental. This strain has all the medicinal benefits of marijuana, without the psychological effects.
Personally, I quite enjoy the psychological high from THC, but for those of you out there truly looking for marijuana purely from a medicinal standpoint, for those of you who need relief but don't want to get high or be cloudy, this it it.
The strain is very high in CBD, and low in THC. It's very good stuff, it can be up to 60 for 1/8, but you can find deals on it too. Very worth it.
