I guess I've never known the really sad people like the ones he describes. A lot of my friends smoke, and they tend to come in two varieties:

1. Those that smoke every day, who will skip on other luxuries to pay for weed. 2. Those who smoke very casually, and typically go for months at a time without smoking. They'll usually only buy more when an opportunity presents itself.

I know very successful, highly skilled and well paid people and I know people who aren't very ambitious - in both categories - and I know those same types of people who don't smoke, or drink at all.

I guess I should count myself lucky that I've never managed to fall into a group of people for whom smoking is a problem, and an addiction, and a weight holding them down.
