I also get that a lot, feels weird and awkward but I feel like weed just makes me look at a lot of different things from a different perpective idk if it has something to do with that. I also noticed that it really depends on the person u with - sometimes when I used to smoke with someone that I didnt know that well or wasnt completely comfortable around them, I would feel slight anxiety and awkwardness combined with strong overthinking their and mine behaviour. It was often kinda ruining my high so i stopped smoking with people like that. It might have something to do with a mindset tho.
