A new study suggests that smoking marijuana as an adult is not linked with anxiety disorders, including depression and other bipolar disorders,Medical News Today Reports. The researchers said, "There was no link between marijuana use and increased risk for mood or anxiety disorders." Mitch Earleywine, a professor of psychology at the State University of New York at Albany said that he was quite "dubious of these findings," the expert added,"there is very little to be concerned about with marijuana. There is more to be concerned about with alcohol or any of the other psychoactive drugs that the drug industry prescribes."

It may sound like good news as more states in the U.S. are legalizing marijuana for both medical and recreational use. However, the latest report says that those who consume the drug may be susceptible to other addictions, "34,653 adults were interviewed in a 3-year interval as part of the National Epidemiologic Survey on Alcohol and Related Conditions. Results showed that, at 3 years follow-up, marijuana use was linked with increased risk of alcohol and drug use disorders, as well as nicotine dependence."
