i think like that too sometimes, like if i never hung out with this person would i still have got this bad? my addiction was to other drugs so its a bit different...but you gotta think if it wasnt your brother on that day would you have been exposed at some other point in your life? probably would have. I dont think its wrong to blame someone, but i know in my situation, i got introduced to a substance, and took off with it on my own. someone asked me the other day if i could have not done the drug what my life would be like. i hate questions like that, but i kinda decided if i hadnt done the one thing, it would have been something else, or drinking...so my answer was that i wouldnt change anything because im not doing anything today. Its easy to blame shit on other people..its harder to find the real underlying reasons as to why we become addicted. Good luck on that trip man.
