I don't get how this is a thing for Americans. How are you not destroyed by anxiety and paranoia if you go get stoned before having dinner with all your relatives?
I use cannabis daily for several years. You get used to being in public high and it becomes less scary and panic inducing.
When I visit my family I must be fried. I can go on several week long vacations without cannabis but the moment my family is near I must be fried for my own remaining sanity.
Three years ago I got high with my 18 year old nephew at Thanksgiving at my place. We were sitting on the porch, family in the next room. Didn't think at the time I was sitting back to back basically with his grandma.
We came back in and she says oh was that some "good shit" or not?
I can speak to this (Canadian, we have Thanksgiving in October, i get high because parts of my family are hard right Conservatives): If I get stoned for dinner (after preparing dinner), I don't feel like shit when people rag on the food or bring up trash political takes. Being high makes me calmer.
Also I don't care if people know I'm high, so that helps.
If I do stay sober, I have to hear how minorities are ruining the country and be accused of poisoning people by not making a healthy meal... which makes me anxious.
Do you worry that the weed impairs your ability to produce effective counterarguments? Drag wouldn't want to go into a situation like that without being on drag's A game. Thanksgiving can be one of your few chances each year to argue with your relatives, so drag tries very hard to avoid wasting it.
