Personally I don't do any drugs such as tobacco, marijuana, acid, ect. I just never found the need to. I do however see points in taking hallucinogens every once in a while (2 times a year) based on what they do for you, and how they break everything down to a very simple level. Anyway, I am not once bit opposed to growing industrial hemp as there are many products that could be made better and more environmentally safe by using hemp instead of some of the other materials. As for the crystals in the plant, who knows what to do with them. I'm not to sure about the medicinal uses but couldn't they use them for that? Or is that something different all together?

EDIT: Also the comment about pot heads being idiots or however you worded it is completely inappropriate. Just because their gpa wasn't higher than 4.0 means nothing. That isn't an accurate display of one's intelligence when you factor in how in most schools homework is a huge chunk of the grade. That might not be the case for your school but I know alot of very intelligent people who didn't get honor roll or high grades just because they didn't feel like doing the homework. That is a different kind of stupid all together though
