Full disclosure: I do consulting work for a number of legal 502 cannabis farms that sell both medicinal and recreational products. Over the past thirty years I have had three gardens that I built and designed make the centerfold of...well, you probably know the magazine. I've also been asked to judge the Cup twice. I know a bit.

First thing I'm going to tell you is that everyone above got it more or less correct. I don't know if they referenced other posts by you but you didn't say why you were taking the product in the first place - but I'll assume pain relief. CBD's are the solution for most types of pain without the psychoactive elements. I wouldn't make THC out to be the bad guy quite as much as I've seen other posters do because it has it's uses as well. In fact, one of the most effective strains for me, a person who doesn't care for the psychoactive properties, has 14% CBD and 14% THC. For whatever reason, I don't feel the psychoactive properties when it is a 1:1 ratio like that and yet, it treats by pain more comprehensively.

There are many strains that are almost completely CBD based however. Charlotte's Web, for instance, has gotten a lot of press with it's effectiveness in juvenile epilepsy. Another that comes immediately to mind is Sour Tsunami #3 which has less than 1% THC-A with 18% CBD.

Personally, I'm a big advocate of patches - particularly with folks who might have a tendency for addiction or emotional escape. CBD patches take the smoking aspect out of it which separates the consumer from the street culture a bit more. They last me twenty-four to thirty-six hours because they are time released.
