Cannabis Faux Pas — What NOT to Do

The definitive ranked list of cannabis etiquette violations — from mildly annoying to genuinely serious. Bogarting, wet lips, surprise dosing, and the classics that will get you uninvited from someone’s sessions for good.

Ranked by Severity

Cannabis culture has evolved dozens of unwritten rules over decades of shared circles. Breaking some of them is a mildly embarrassing moment. Breaking others will cost you friendships. This is the ranked list.

The Serious Ones

  1. Surprise dosing — giving someone an infused edible without telling them. Not a prank. Not funny. In several states, it’s also a crime. Lizzie Post: “You don’t pour all your different alcohols into decanters and leave them unlabeled.”
  2. Driving impaired — no matter how legal cannabis is in your state, cannabis DUI is real. Every legal state has per se or impairment standards. Rideshare or stay.
  3. Sharing with minors — universally unacceptable, criminal in every state, and the fastest way to lose adult friendships.
  4. Consuming around unwilling pets — cannabis is one of the top 10 most common toxins reported to Pet Poison Helpline. Edibles left accessible to dogs is both a faux pas and a vet bill.

The Classic Session Sins

  1. Babysitting the joint — holding the joint while telling a story, “fuckin’ up the rotation.” The #1 most-cited faux pas across every cannabis etiquette guide.
  2. Wet lips on shared joints — GreenState: “There is no greater shame than spitting on a shared cannabis joint.” See wet lips.
  3. Torching the whole bowl — also known as giving a “greener” (see greener). Corner the bowl.
  4. Dirty bongs and crusty bowls — Herb.co: “If you’re inviting people over, clean your bong. Refresh the water. Scrub the bowl.”
  5. Smoking with a shared piece while sick — a faux pas before COVID, borderline offensive after. See smoking sick.

The Quietly Irritating Ones

  1. Showing up empty-handed repeatedly — Herb.co: “Sharing is caring, but habitual mooching will get you quietly uninvited.”
  2. Lighter leeches — the most common unintentional theft in cannabis culture. Check every pocket before you leave.
  3. Gatekeeping newcomers — strain snobbery, flexing, making first-timers feel unwelcome. Modern cannabis culture strongly rejects this.
  4. Blowing smoke in someone’s face unless specifically doing a consensual shotgun. Always exhale away from others.
  5. Pushing someone who’s said no — Lizzie Post: “Offer once. Believe them when they say no. Don’t push.”
  6. Not asking before lighting up at someone’s home — always ask the host.
  7. Pretending to know more than you do — exaggerated knowledge about strains, terpenes, or effects looks foolish to anyone who actually knows.
Most of These Are Fixable

Almost every cannabis faux pas can be repaired with a sincere apology, a contribution of something nice to the next session, and not doing it again. The one that cannot be repaired is surprise dosing — people remember that forever.

Why Any of This Matters

Cannabis faux pas aren’t arbitrary rules. They evolved to solve real problems — fairness in sharing, dosing control, hygiene, consent. Almost every rule can be traced back to either respect for the group (rotation, cornering, cleanliness) or respect for the individual (consent, dosing awareness, not pushing). Lizzie Post’s three principles apply directly: consideration, respect, honesty. If you’re uncertain about an action, run it through those three — and you’ll almost never go wrong.
