In high school, I smoked three times. I was a "C" student, voted Class Clown, was kept out of higher classes because I was a wise-ass to my teachers, was often late for school, and, made it into college because my SAT scores helped me get a baseball scholarship to a four-year school. My first semester of college, I smoked daily and made the dean's list.

Just don't slip into harder drugs. I started to, but, a brain-injury ruined the effects of all of them, except cannabis- which it magnified. Keep learning and keep reading.

And, to answer your question- Cannabis helps every aspect of my physiological system.
