> The issue is that people adjust their consumption accordingly

That was definitely not true in my case. I used to consume pretty high-% THC hash throughout the day. At first it was strong and I did it once every day or two. But you get tolerant and can handle a lot more. Eventually I was smoking hash several times a day and I ended up with a lot of the symptoms described in this article (though I am in my 30s). I realized I needed to quit, and the off-ramp was terribly long and frightening; I was very hooked both physically and emotionally and I haven't touched any form of THC since, though it did take me close to a year to feel normal again.

Interesting to me that sharing my experience with THC addiction has deserved downvotes. Sigh.
