probably my best friend in life totally changed after smoking pot. Gradually, at first he was just lazier, slower, more mellow but as he got older, he got more and more paranoid, more and more reclusive and I always suspected he moved on to other drugs but I don't know. He attacked me the last time, not physically, but morally like I was out to get him or something. It was weird. I swore then I'd never even deal with another addict, period. Not argue again about how it's not that bad or that it's good or whatever or deal with the shame that they project.
Waste of time to have them in your life in general. Even the people that can handle pot that I know of are just goofy and make silly mistakes and slow you down if you're working with them.
It's why I told my cousin "you need treatment" didn't and won't waste another breath on him, I didn't raise him, I didn't fuck him up and I'm not gonna get drawn in. My brother is a different story, I only wish I could forget about him. Instead, I had a sore throat this morning from hanging out at his place last night.
