Don't do drugs, period, and you'll be fine, be a role model to those around you, your life will thank you in the long run.
Nooo it woooon't. I was pretty fucking obedient until I was 20 and I can say since taking up the green at mid 20s and mdma slightly later, being s0ber sucks the fat one. There's some things in life you gotta be straight for, but for the rest of it, it's totally not worth it.
it would take more than cocaine to make my dick small. maybe some time in a wood chipper. but that might just break the wood chipper.
