I'm curious about drugs — in particular what happens when you chemically combine methamphetamine and PCP and how it might affect the body. Some places online say they're the same thing, but I'm not so sure.

My uncle shoots heroin. My father used to do cocaine. My moms' (both of them) used to smoke weed with their friends when I was eight. I smoked weed when I was twelve. I sold weed at 14.

I don't want to continue in the vein of my addictive family (no pun intended). How hereditary is addiction? What measures can I take to avoid falling into the same hazy trap of my family members?

I know all the effects smoking has on the body, but nobody seems to have information on what it does to your sex life. What are the effects, like dryness, de-sensitivity in areas, etc? If I quit, would sex be better?

I am a freshman on a collegiate varsity sports team. Team gatherings, when we are not practicing, usually consist of excessive drinking with and without drinking games. I did not drink in high school and when I tried drinking with the team it made me feel really sick. I want to bond with my teammates (they are really great when not drunk) but I don't know how because if I am the only guy in the room not drinking I can't play drinking games with them, discuss favorite types of alcohol, or even carry on a real conversation because at a certain point in the night they stop forming coherent sentences. I need to be friends with this group of people but I would like to do so in a way that allows me to remember the night in the morning. Is this possible? What should I do?

While I don't really approve of their lifestyle (why devote six days a week to practice only to reduce your performance with alcohol?), I make no moral judgement. I don't want to change their way of doing things, I just want them to respect my way.
