According to a new study, marijuana doesn't actually cause depression or anxiety.

Previous studies had already suggested that using marijuana may not be totally beneficial to a person's mental health. It is said to cause short-term paranoia and even responsible for causing new form of psychotic disorders.

However, a new research suggest that cannabis usage is does not actually increase the risk of having some anxiety or mood disorders.

The research was conducted by examining the data of almost 35,000 adults in the United States. They were then tasked to participate in the National Alcohol Related Conditions Epidemiologic Survey in which their marijuana habits were checked and examined.

After three years, the data collected were then analyzed in terms of the participant's mental health. During the examination, external factors like family environment and psychiatric disorders background were also considered.

The result showed that the use of marijuana doesn't cause any depression or anxiety at all. However, the study showed that those who use marijuana can have an increased chance of developing alcohol, cannabis and other drug use disorders.

In the study, those individuals who are using marijuana have three times higher chance of having alcohol or other drug use disorder. The chance of being nicotine dependent is also increased by two times for those who use cannabis.

In terms of the legalization of marijuana use across the US, the researchers stated that the government should first consider the result of their study before deciding.

"Our findings suggest caution in the implementation of policies related to legalization of cannabis for recreational use, as it may lead to greater availability and acceptance of cannabis, reduced perception of risk of use and increased risk of adverse mental health outcomes, such as substance use disorders," the researchers wrote.

The new research was now published in the journal of JAMA Psychiatry.
