When does recreational drug use become a problem? Recently i've noticed that i've been doing more and more coke. I need double the amount my friends do to get the same effect and i've started doing it alone at home. I just feel like I can't function without it - I start feeling irritable, tired and depressed. I spend more money on it than ever and I don't really feel like eating anymore. I can't experience happiness, or even function properly unless i'm high. I also smoke lots of cannabis (which i've been doing for many years) and have taken other drugs in the past. I don't really feel like I can talk about it without being labelled a 'cokehead' or something. I can't talk to my friends because they do drugs themselves every weekend and would laugh at me for being so weak. It's funny because my father is a specialist in drug addiction/alcoholism and goes to prisons and hospitals giving people their methadone. He'd be so disappointed in me if he knew that I wasn't much better than the people he treats. I guess I could just continue to do it until I end up dying..
