Tips for Cannabis Costumes

Know your audience. Cannabis costumes are great for parties where the crowd is friendly to the culture.

Read the room before committing to something bold.

Comfort matters. Inflatable costumes are funny but hot after an hour. Body paint looks great but transfers to everything. Plan for a long night.

Keep it fun. The best cannabis costumes are playful, not preachy. You are at a party, not a rally.
