"Usually these people will tend to use you for money, drugs, or assistance, and if neither of those things apply they won't give a shit about you."
OMFG SO WRONG! FOR GOD SAKE how can you say that if you DON'T do it, NEVER did it and plus NEVER HAD a friend who used drugs? Holy jesus, I got really pissed off reading this because for about 2 years of my university time I used to do some stuff, and that ended up getting me closer to some friends who were into it as well, IT WAS GREAT AND THEY'RE STILL MY BEST FRIENDS. I kinda stopped for my own personal reasons, some of them still do it though, and NOTHING changed. I mean I don't hang out with them that often anymore because now I'm working and finishing university, so I can't like go to someone's place and stay there for the night, smoking weed (or doing some allucination drug or whatever funny shit) and only coming back home early in the morning, or else I'm gonna be late for work etc. In fact, most of them don't do that anymore, we have all grown up and know about our own responsibilities.
To lockwood, I feel very sorry for you man :/ Hope you will be ok.
