An advocacy group in the United States is seizing upon a study that found students smoking marijuana can get good grades like any other student.

The Marijuana Policy Project, a national pro-pot group that wants to decriminalize marijuana, is promoting a new Swiss study finding that teens smoking pot also have strong friendships and weren't more likely to be depressed.

A state lawmaker criticized the study, calling it "academics gone wild."

"It's really outrageous," said Rep. Peter Koutoujian. "I'm appalled."

Bruce Mirken, a spokesman for the Marijuana Policy Project, hopes that the study will show that the government "twists the data to try to frighten parents about marijuana."
