One telltale sign is craving oxygen haha, I smoked a huge bag of shake with a friend a few summers back and all I remember is saying "man.. we need to breath some oxygen.. or something.." LOL we stopped smoking after that and took a "oxygen" break. (air, not actual oxygen lol)

(pretty high right now, sorry if any mistakes lol)
