I very, very rarely smoke. I just don't function very well when I'm high, and my life is too busy to waste on a non-functional day. Every few months or so, I will blaze up and watch Steven Winwood and Eric Clapton At Madison Square Garden or something, but for the most part I'm just not into it. It makes it tough to evaluate new strains; I have to give free samples to friends and say, "here are 5 bags, numbered 1 through 5. please take notes and let me know how each smokes, and - well, enjoy it!"
I grow for two reasons - first, because I absolutely, positively love the plant - the smell, the look of it, everything about it; and second, because it's my life's goal to find and grow the best medical strains that I possibly can. So I grow commercially on a relatively small scale to study the characteristics of different strains, and to help finance my quest to find and/or develop some top-notch medical strains. I know that for many people, good medical marijuana makes the difference between a life that's unbearable and a life that's livable and even enjoyable, and in some cases perhaps the difference between a life and no life at all - literally. This is something I happen to be very good at, and something I love doing, and I feel that it's what I am literally meant to do at this point in my life.
