Ask PG: Does smoking marijuana affect the ability to hack and run a startup?

Throw away account. I have a startup in San Francisco, and smoking weed actually is quite therapeutic. It is an outlet for stress and the never-ending wall of burden. Development and startups are evolving so fast, and it often feels like you are never adequate. You always need to be learning and using X new language or technology. My startup is the hardest thing I've done so far in my life.

The culture of San Francisco also is heavily accepting, even promoting of smoking marijuana. Often times it feels like some of the best hackers I know smoke on a regular basis.

However, there are noticeable side-effects. Some short term memory loss, sometimes I find it difficult to stay focused, on-task, and motivated. On the flip side, I do some of my best hacking high. I'm able to focus on a single problem; become tunnel vision. Problems just become simpler.

Thoughts? Can, and should a startup founder, as a leader, and public face of a company smoke? Can you be an amazing hacker smoking consistently?
