We didn't say selling it. We said smoking it.
I'm 14, I have an A average, and I have basically never failed. I smoke weed every weekend, and sometimes before finals or mid-terms. It calms me down, helps me stay focused and relaxed. It doesn't hurt my body near as much as any other drug, and it lasts twice as long. The only negative effect, is if I don't actually put in an effort to stay focused, I'll just drift away. But I can easily snap back into realization, and if something were to happen, I could be completely down to earth about it.
I say it's great, compared to anything else.
