Yea i get that sometimes as well. I'll just be hanging out and all of a sudden feel a little high or goofy or something. Usually its in a situation where it triggers the memory of being high I.E. being around other smokers, seeing someone smoke on tv, something i would find funny high etc. For me its mainly just little things that trigger that feeling that have to do with weed idk though maybe if you smoke enough you produce a little gland to keep you goin when you run out
haha only joking.
