In the first half of the 20th century, Americans looked to author and socialite Emily Post for the do's and don'ts of proper manners. Why? She wrote the book on it, literally, with 1922's Etiquette. She wasn't concerned at all with cannabis. Her great-great-granddaughter Lizzie Post sure is, though, as evidenced by her 2019 work, Higher Etiquette.
Yep, there's an entire book on how to be a good consumer of cannabis. But there are also a few things that shouldn't even need to be said about it — the simplest ways to be a decent human being while catching a buzz.
First, don't litter. This applies to everything, not just cannabis, but there's a lot of trash produced by this industry so it's worth repeating. Stop making stoners look bad and walk over to that trash can.
Now that we've covered that, it's time to know your audience.
If you're smoking alone, it's no big deal to light up the entire bong bowl with one hit. But when you're sharing with friends, you don't want to be a hog. That's what the saying "puff, puff, pass" is all about. A joint needs to work its way around a circle for everyone to enjoy it. Same goes with a pipe, so leave some for the next guy.
Speaking of the next guy, they're going to put their mouth where yours just was. So keep it dry.
Cannabis isn't usually consumed with strangers. It's something done with friends. So, the key to being a good person while consuming cannabis might just be the same as being a good friend. It's not hard to have good manners, and it's not any harder to have good manners with cannabis either — though it's definitely more fun.
