So, I'm writing a fic where I have to depict the symptoms of both cocaine use and cocaine withdrawal (three guesses what fandom it's in, lol). I've been researching on the internet (trying to find reputable sources), but I'd also like to ask here, because there's nothing quite like getting an answer from a real person who has done really extensive research or has familiarity with the issue through their job/life experiences or has observed these symptoms first- or second-hand.

So...yeah. Hope this isn't rude or insensitive, but I'd like to know if anyone wants to help me out!
