The hyperfocus I experience while mildly stoned leads to some incredible breakthroughs, and many happy hours of progress. I find it allows me to keep a much larger amount of state in my mind at any given time, and makes my state memory more resilient to distractions like Facebook notifications and emails. It also dramatically improves my patience (a quality I normally lack), so I can hack away at a difficult problem for hours at a time.

Many of my favorite personal projects come from (or at least start during) a marijuana session.
