I usually just smoke one puff and it doesn’t have strong effects. I’m sure this would be more effective in general compared to pills, so I don’t agree that we should dismiss this advice based on “oh it’s drugs”.
Oh for sure, compared to pills (even OTC stuff with significant hangover effects like Benadryl or Nyquil), it absolutely deserves serious consideration. I would recommend trying melatonin, chamomile tea, and simple mental exercises (eg. counting from 1 to infinity) first though.
