With the coronavirus spreading throughout the U.S. and the world, marijuana users have to adjust to the new health paradigm. That means no sharing of joints, pipes, bongs and vape devices.
If you must share for some inexplicable reason, use the chillum smoking method by placing a joint, one hitter, vape pen or an actual chillum between your index and middle fingers, make a fist and close up the holes with your other hand before inhaling. This works remarkably well.
Otherwise, follow what they do in Jamaica and other countries: Smoke your own. When you light a joint amongst a group, DO NOT pass it. Encourage others to do the same.
Unfortunatey, there is no evidence that cannabis is a cure for the COVID-19. So please be careful during this very senstive time and do not share germs with others around you. It could be matter of life and death.
