You wouldn't light up a cigarette in someone else's home without asking, but how about a joint? Thanks to the 2018 Constitutional Court ruling, which legalised the private use of the plant, we're entering a tricky phase where you could be offered some dagga at your next dinner party.
This situation is a potential minefield of social faux pas for weed smokers and non-smokers alike. And, that's where Lizzie Post's etiquette guide comes in.
Called Higher Etiquette: A Guide to the World of Cannabis, from Dispensaries to Dinner Parties (Ten Speed Press), it's all about marijuana manners.
What adds to the book's quirky appeal is the fact that the author is the great-great-grandaughter of Emily Post, the woman who wrote America's etiquette bible in 1922.
