If someone is getting high for the first time, I think it is common courtesy to lead them through the experience, to “hold their hand” so to speak, because they are inexperienced.
When someone is a regular smoker, however, I expect them to understand the little unwritten rules that guide our culture.
Potheads have etiquette, you see, and when you smoke with other people, there is a certain code of conduct everyone should follow. For example, never pack a bowl out of someone else’s medical cannabis supply. In fact, you should never touch another person’s medical cannabis without their express permission! Medical cannabis is expensive, and in some cases it is only available by prescription, so taking some without asking is the same as going through their bathroom medicine cabinet and eating their pills! You wouldn’t do that, would you? Treat medical cannabis with the same respect, and if you do, chances are good that person will get you high anyway. This is the nature of smoking medical cannabis, it gets you stoned and your instincts are to share it with those around you. I firmly believe medical cannabis is a communal experience, and you get higher with other people then you do by smoking alone. In the era of COVID, sharing a bowl of medical cannabis has fallen out of fashion. Cannabis edibles are becoming more popular just because they are clever, easier to share, and don’t induce coughing fits. Coughing in the middle of a crowd smoking medical cannabis is not a good look, when so many people are still getting sick.
