Well, Colored hairs on marijuana as well as no seeds usually means potent. like 15%-24% THC, very potent stuff. If a user is used to smoking what it seems like is schwag (marijuana with seeds, that is weak, cheap, outdoor grown) and then smokes some hydro (indoor grown, hydroponically grown) then there will be a totally different experience, not to mention the two main different strains of marijuana, Sativa and Indica. Indica, which would be better for the patient makes you feel more relaxed and kind of locked on the couch. While Sativa is an energetic high, so it really depends on what the patient wants. Make sure that the patient is using marijuana in a controlled setting that is comfortable with him, and also that he pays attention to his tolerance, not necesarrily to smoke till he's high but rather stop after a few hits and judge from there. The other day I took two hits of some good stuff, I was left very high, but at that time I felt like I wasn't going to get high at all. Hope I answered some of your questions. Now if you could do us a favor, and get marijuana legalized for recreational use, in small portions of course!
