A coworker has been using cocaine for about 3 months now. She says this is not a problem because she just has to quit in the next couple of weeks. She says that you only get addicted to cocaine if you take it for more than 4 or 5 months. Or at least that is what she claims happens with her. This is such a confusing topic, because I really have no idea how long you can use cocaine for before you get addicted. Is there really a magical 5 month addiction mark, or is that her excuse?
