Marijuana Linked to Teen Mental Health Problems
Teens who've reported being depressed at some point in the past year are more than twice as likely (25 percent) to have used marijuana than those who weren't depressed (12 percent), according to a White House Office of National Drug Control Policy report to be released Friday.
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, theAssociated Pressreported.
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.
The report authors analyzed data from about a dozen previous studies that examined marijuana use.
"Marijuana is a more consequential substance of abuse than our culture has treated it in the last 20 years. This is not just youthful experimentation that they'll get over as we used to think in the past," John Walters, director of the drug control policy office, told theAP.
Since 2001, marijuana use among American teens has decreased 25 percent. Currently, about 2.3 million children use marijuana at least once a month, according to the drug control office.

New Formulation of Coagulation Factor Approved by FDA
A new formulation (NovoSeven RT) of the genetically engineered version of Factor VIIA -- a plasma protein essential for the clotting of blood -- has been approved by the U.S. Food and Drug Administration. With the new formulation, the product can be stored at room temperature (up to 81 degrees F) for up to two years.
NovoSeven RT shares the same uses as the earlier NovoSeven including: treatment of bleeding and the prevention of surgical bleeding in patients with hemophilia A or B who have antibodies that neutralize the action of clotting Factors VIII or IX; treatment of bleeding and the prevention of surgical bleeding in patients with congenital Factor VII deficiency; and prevention of surgical bleeding in patients with acquired hemophilia, the FDA said.
