I believe that marijuana is a drug in the same sense that caffeine is a drug. You can become mentally and even physically addicted after enough time and daily use, and it's use can affect your daily life and health. Caffeine can cause sleep disturbances, cause anxiety, and agitate previous conditions. It's also not very good for the heart. In the same way, marijuana can cause changes in social behavior, thought processes, and can even influence who you choose to associate with. Would I consider marijuana a drug in the same context that cocaine and heroin are drugs? Not quite. Those drugs, in my personal opinion, are much more likely to cause physical and mental dependence in a shorter time span with less uses before addiction is achieved. Not to mention the social stigma associated with these "hard drugs".
