All of that is insanely stressful and I would argue if weed would have caused issues, I would have had larger problems.
I did say "If you have your s... more or less together, you can probably use weed semi-regularly without too much damage."
I'd even expand my argument, and say any vice including videogames, cars, etc. Anything can get out of hand if people are trying to avoid a problem.
People use many things as psychological crutches, yes. What I'm arguing is that some of the specific effects of weed (esp. the effects on cognition) make it more dangerous than other crutches.
