Hi there, and thanks for your question. Cocaine can have all sorts of effects on a person, depending on their height, weight, age and mental health. Taking cocaine for a long time can cause weight loss, but it can also have some other really bad side effects like insomnia, depression, anxiety and paranoia, psychosis, hallucinations and brain damage. Cocaine is an addictive drug, which means that you can become psychologically and physically dependant on having it in your system, and that you find it harder to function without it.

If you are thinking about losing weight, there are plenty of healthy and legal ways to do this. Exercise and a healthy diet will make you feel much better than using drugs could, they don't have the nasty side-effects, and they're much cheaper too! Have a chat to your local youth worker or counsellor, or even a GP, about ways that you might be able to lose weight and stay healthy. Take care of yourself, and good luck.
