Why marjiuana isn't legalized?

Answer 1

The only reason it's not legalized is because 1) the government can't put a tax on it 2) It can be grown anywhere thus creating weed plants that the gov't couldn't stop because of private property

Marijuana can be taxed and has been before now.

Growing on private property is not enough defence against arrest and prosecution.

Legalizing marijuana would be an endorsement of an antisocial drug that sometimes makes sensitive people crazy. The smoke gives people cancer. Legalizing marijuana would add to the social, health and economic problems brought about by drinking alcohol and smoking tobacco. The US government tried to ban alcohol, but too many people were willing to break the law. Since marijuana is already illegal and most people still accept that law it would be unwise and unpopular to change it.

Some bad things are accepted because most people allow them. Marijuana isn't accepted by most people (some local areas buck this overall trend).
