So, I've been pretty straight edge my entire 18 years of life, but I had dated a girl who was a meth addict and upon trying meth twice, I noticed that I didn't experience anything and had no coming down period which I often saw her experience. Both times I had more than 4 lines. After a while, a friend offered me some weed to see if that could get me high. I smoked approximately 2 grams, still no high.
