I always thought marijuana smoke was far harsher (unfiltered, too) than cigarette smoke.
And we all know the dangers of cigarette smoke, as beaten into our heads over the past 60 years.
Do you know anyone who smoked 40 joints a day?
How about 2 packs of Marlboro?
I don’t smoke anything, but total load matters significantly.
A glass of wine a day won’t hurt you. Three bottles a day will.
