Everything said there applies to smoked/vaped tobacco as well. Should we ban it?
a dust mask that doesn't make a tight seal against your face and was designed to stop only a percentage of particles a thousand times larger than coronavirus particles

You don't know jack, bigmouth.
Good morning to you too sunshine!
As usual you show off your stunning pot addled intellect.
Dust masks do two things for a person coughing or sneezing with coronavirus. 1st they help turn larger droplets with viral particulate which would harmlessly drop to the ground into smaller aerosolized droplets which form a cloud that floats around for an extended length of time others to breath. Second, they concentrate the viral particulate that your body's immune response is trying to get rid of in your nasal cavities and increases the chance that the virus will infect your brain by traveling up your olfactory nerve channel.
Quick hand me a mask, I want to virtue shame non-pot smokers.
