Anecdata: I've noticed a huge range in the way people are affected by chronic weed smoking.

It seems like most people tend to become more content with their current situation and happy to enjoy the moment. This seems make most people less motivated, maybe because they have less problem with how things are.

But there are outliers: I've met a few folks over the years who are voracious weed smokers, and have an outrageously productive output.

I'm not sure if it's because people are simply wired different, or if these latter camp just figured out how to use weed really well.
