Many people believe that marijuana is harmless, but that is completely not true. Marijuana can cause cancer and leads to lung damage, brain damage, and violence. No matter what people say, the government can't legalize marijuana, as it would be dangerous to society. Most states are doing the right thing by keeping it illegal.
It should be legalized because it has a use other than to get high. people use marijuana to to relieve stress and pain. People with cancer or other painful diseases have used marijuana to reduce pain and increase their hunger so that they are able to eat something.
