Hmmm tricky one

To be honest when I first started smoking as a student all we could get was shitty soapbar.

Even after 12 years of smoking if I take a break and get some good buds I can get a lot more of an intense high, but that's because I get MUCH better weed now.

I think in a way there is a psychological element to tolerance - like you say we grow up a little and learn to "handle our weed"

TBH though I took a break a few months back (2 weeks) as I was on other medication and the first smoke after that was dynamite, my head was zinging and I got the rushes and the giigles and everything.

If you smoke kick-ass weed for years on end then it would probably be different but that didn't happen to me, the quality of weed I get just gets better.
