I've been an avid smoker longer than a programmer; although, these days I get high as means for keeping my left-hemisphere in check, which helps new ideas breathe, but the biggest reason I keep smoking is to forget. Forgetting is good if tend to worry to much, while psychologists typically have an entire lexicon for the word anxiety, which is more or less a state invoked from worry. Getting high helps me forget all those nouns/pronouns for a brief period and just sort of float around.

These days I can make an 1/8th (~3.4 grams) last a good +2 weeks.

Believe it or not though, my life long dream is to move to India, get in contact with a spiritual guru, and live in the now for as long as I can.
