Apparently your attention span was to short to keep reading so you understood why it is a bad idea. It is not open to argument whether someone stoned passing around a joint, or recently vaccinated being around others recently vaccinated, is an idiotic thing as an incentive.
Same thing as telling everyone who isn't vaccinated to start kissing each other in the former, or to have never worn masks in the latter. Science for the win.
Weed a bad thing? For most people yes. You can tell they are too emotionally immature to do drugs by the way they can't stay level headed in a mere conversation about it. All by yourself you prove yourself wrong.
Like anything else in life, it takes a certain level of maturity to do something responsibly, particularly when it is mind altering such that it has a potential effect on other safety related daily decisions.
