The paper also said that marijuana use by teens increases their risk of developing a mental disorder by 40 percent, and that teens who use marijuana at least once a month for a year are three times more likely to have suicidal thoughts than those who don't use the drug, the Associated Press reported.
In addition, teens who smoke marijuana when feeling depressed are more than twice as likely as other teens - eight percent compared with three percent - to abuse or become addicted to marijuana, the report said.
