The first time I did shrooms I bought an eighth, I was the only one who had any so I ate most and smoked a bowl with my friends to "share". Remember....I was only 18. We smoked out of a pipe and it tasted like shit. after a couple of hits no one could bare the taste anymore. I fried hard, cause I ate 3 grams, but no one else felt more than the weed we had smoked prior. six years later, about to graduate college, and smoking weed everyday for eight years I can say I have seen no effects negative/positive/shorterm/longterm besides the shitty taste I got in my mouth. Embarrasing story..............
