I've only had two bad experiences with weed. Both times I was at my brothers smoking with him. I think it has to do with my mindset when I'm smoking with him. Unfortunately if I smoke with him strangely it's not to get high, but to prove that I can handle just as much shit as he can. Bad idea for sure. When I'm smoking for a reason other than to just get high and relax I feel the effects much much more. So I'll smoke 3-4 bowls with him, then I usually think "shit we smoked 4 bowls I'm gonna be way too fucked up." then the effects are intensified even more and then I just feel like everything is spinning and I get sick. If I could just get rid of this stupid ass idea that I need to prove myself to my brother, I'm sure I wouldn't ever have a bad experience like that again. Lately, though, I've taken on the mentality "I am who I am, I don't have to prove anything to anyone, I'm just going to live my life how I want to live it.", so I'm pretty sure next time I go up to see him I'll be fine. If I don't think I'll be able to do it, I'll just go up when he doesn't have any weed and I'll only take enough for two bowls max and I'll be able to actually experience being high with him without getting sick before we can even do anything.
