My folks caught me in highschool, tennis practice was cancelled so I went and smoked with some friends. Got home and my mom was all worried (she had driven down to the tennis courts and nobody was there). My pops was a doc, so they were gonna have me go to the hospital and get tested, I wasn't about to embarass my dad like that in front of his coworkers so I fessed up.
Smoking weed is a recreational thing, sorry if I sound like a parent but you really should only smoke when you have free time. Yeah I smoked in highschool but I always smoked after. Don't screw up school, might not seem that important but it is. I was lucky my parents were crazy about school, I finished 3rd and it wasn't good enough, I got a 1500 on the SATs my mom wanted me to retake it, she made me take college calculus and chem while I was in highschool...and I thank her everyday for being so unbearable.

Just look at the economy, with technology and automation all these manufacturing jobs are disappearing. It used to be only teens would work registers at McDonalds now I see all these folks in their 30's and 40's behind the counter, it's really sad.

anywho, do what you will, just think about it. You don't get a second chance at highschool, and it determines what colleges you can go to. sorry for the preaching.
