I do drugs cause they make life easier to live through. I have varying mood levels, sometimes I just feel like total shit and other times I couldn't be happier and both for reasons that are not outside influenced. I smoke weed to bring me 'up' when I'm feeling down. I take Opiates when I can get them cause I enjoy that mellow body high and love the feeling of melting away all my insecurities. Opiates are really something I use to escape life from, while weed I smoke just to enjoy life.
As for my LSD use, I trip cause I love the expansion of thought it gives me. I always come to some conclusions about life when I'm tripping, and those conclusions stay with me forever so to me it's a positive. Not to mention I love going to raves and tripping balls cause, well, who wouldn't want to with all the good vibes and crazy visuals? Not to mention the blending of senses is unlike anything I've ever experienced. Seeing sound in waves of color is unbelievable.
