Smoking marijuana is becoming even more popular among U.S. teens and they have cut down on smoking cigarettes, binge drinking and using methamphetamine, according to a federal survey released Monday.... The increase of teens smoking pot is partly because the national debate over medical use of marijuana can make the drug's use seem safer to teenagers, researchers said.

Smoking marijuana is safer than smoking cigarettes, binge drinking (any kind of drinking), and using meth, so American teenagers should be praised for their good sense and good judgment.
