I find plenty of places across the US with 1/2 g joints which I think is still too much. People at parties still roll tiny joints which seems to be just the right amount.
As for a putting out a joint, I just scrape off the cherry. Not sure what the issue is there.
Preroll joints will always be a ripoff, they’re designed to look flashy, not for function. That’s why you can’t smoke the first half of it really.
Efficiency of high is an economics problem, not really an individual problem. No one ever says this Bacardi 151 has too much alcohol, for good reasons. Still the stress is there. However over the decades of cherishing what little stash I had vs now where it’s always plentiful, I have surmised the ultimate anxiety suppression statement:
Don’t panic there’s always more weed later.
