it's a hobby, personnel use and a sense of accomplishment. and i'm kinda a nerd so i joke that "it helps me be popular".
i can't eat them all by myself though, i took ~200g to a lake party/fireworks, ~10 people ate some mushrooms and i made a spiked alcoholic beverage for a few others that wanted an easy dose, cranberry juice/vodka/shrooms mixed and soaked for a few hours in the cooler. i was still tripping at sunrise.
i trade for other drugs, often and at a favorable exchange rate.
