The eyes are the only give away. That's why I GOTTA get some eye drops. I don't mind my eyes being red around the house but there has been times before when I was extremely high and had to go some where and my eyes were fucked. If my eyes weren't messed up I could easily be high without anyone knowing lol. They are giveaway because they are red, puffy and low or squinted. I smoke so much and still my eyes doesn't get red until like...probably 2 hours into my smoking session so I'm alright haha.

..oh shit I forgot today was Friday lol!
