In Massachusetts, marijuana is officially out of the shadows and into public life. As a result, many are now finding themselves in uncharted social terrain when it comes to consuming and discussing cannabis.

In her new book, “Higher Etiquette: A Guide to the World of Cannabis, from Dispensaries to Dinner Parties,” Lizzie Post hopes to help people consume cannabis, but with a little bit of class. Post’s book seeks to solve some of the questions that are inevitably going to come up after legalization, such as a guide to the differences between bongs, pipes, spliffs and blunts, how to politely cough in public after taking a hit from a bong, and how to be open about marijuana consumption with friends or significant others who are not as fond of the plant.

“When you take something like cannabis and you lift it out of prohibition and you bring it into a legalized form, and make it available to everyone, it becomes a bigger issue when it comes to social interaction,” Post said. “We have so many more products and methods that we are dealing with and are available to us today that it is a bigger beast than it used to be.”

Etiquette is in Post’s blood.

In 1922, her great-great grandmother Emily Post first published the book “Etiquette in Society, in Business, in Politics, and at Home,” a primer for proper manners during the Jazz Age. In 1946, she founded the Emily Post Institute, which is dedicated to updating Emily’s list of rules to reflect changes in social values over the years.

Generations later, Post is now the co-president of the institute, and joked that the idea to write the book was born out of several jokes with her co-workers about the lack of organized principles for how to properly consume marijuana.

“What was really fun for me was after years of being a cannabis consumer and being an etiquette author at Emily Post, to combine the two, because it was certainly a joke in the background for a very long time,” Post said.

While the book is sure to excite frequent consumers, Post also wants the uninitiated who might be weary of marijuana to feel comfortable around it. Post hopes that her book can also introduce a new group of readers to a community she likes, for the most part.

“It was really wonderful to get to really highlight this community, and the fact that it’s an extremely courteous community in a lot of ways,” Post said.
