i find that as the pot head gets older he tends to just smoke it more like a cigarette....just holding it in for a few seconds and lets it out....because my theory is that their state of mind changes about it....instead of "oh dude i'm going to get soo fucked up this shyt is tight as fuk blah blah blah" it becomes "goddamn work sucked today i got yelled at by my boss i had to fill 3 times the ammount of orders i need to relax blah blah blah...anyone else experience this? of course by my theory you would have already had to experience it which would mean older smokers.
