I was the running joke when I went home for the holidays; the code for smoking weed became "feeling nauseous" because of my notoriety to treat my acid reflux and nausea with marijuana. If my step-brother saw me sneaking away he'd pipe up, "You must be feeling a little nauseous, huh?" or when my cousin would sneak away someone would ask her if she was feeling nauseous. But hey, it works, my gastroenterologist even acknowledged it as legit.
I think my mom is even beginning to acknowledge this as well, so when will the government? Always, always the question.
