I dunno; a lot of stoners like to be doped up on a regular basis so there must be some kind of enjoyment there.
Stoners like to get doped up, I agree....but their trend is usually to do a joint get through X number of hours in a less stressful state (as they perceive) and then repeat that six hours later. The amount of THC goes up every couple of months to meet the body adjusting to it. At some point, the guy maxes out.
The whole stoner thing is that they find some little world they can live in and not stress out. If a stoner didn’t have a friend or relative to sponge off...they’d eventually be the guy living under the bridge and just living for the minimum existence factor. I’ve seen those characters in the US, and I’ve seen them here in Europe.
