Why unfortunately? I think this is correct. Why legalize a substance that promotes the disconnection of human consciousness? This is a provocation of the crime. Now legally alcohol and what good is that?
Marijuana relaxes the human mind and body, just like alcohol. If used in moderation, it does no harm to the body. However, some people get addicted to these two substances, and end up inebriated from overdose. Now you can't blame marijuana and alcohol for the troubles created by such people. Also, the fact that a few of the marijuana users doesn't behave properly can't be used to deny it to everyone.
