I'm just curious. I don't do heroin, I'm just wondering what a person acts like when they're on smack. I've read about how it makes you feel + nodding etc. but like if you did some, and then went to go meet with someone or whatever, how would you act? (as in if you're not alone lying in bed or something the whole time ). I met this guy on coke a few weeks ago who had a ton of energy and was acting quite weird and jumping around the whole time, so it was pretty obvious he was on something. I'm wondering if there are any signs like that when on heroin (even though I know they'd be different).
