If you attend a bachelor party where you don’t know most of the people, and somebody offers you a pot cookie, politely decline.
Or accept… and then spend the next two hours questioning why you were even invited to the party, when you are obviously a complete loser that nobody likes. Spend an entire dinner sitting uncomfortably across from two dudes you don’t really know and wondering if they are totally weirded out that you haven’t said a word in what seems like hours. Focus intently on how every move you make is unfathomably awkward and strange. Hold in your pee for like an hour because you think it may seem weird if you get up and go to the bathroom. Keep trying to convince yourself that this is just the pot making you paranoid, and that the other 12 people at the table aren’t all secretly laughing at you behind your back. Pray to god that you start to feel normal before the strip club, because interacting with strippers seems like the worst possible scenario in the world at that moment. Yup, just politely decline, even if they say it’s mild. Trust me. It’s not worth the risk.
