25% MORE teenagers are addicted to marijuana in states where it’s legal

In states where marijuana is legal, there is an increase in ‘problematic’ use among teens and adults, a new study suggests.

Researchers found that harmful marijuana use, known as cannabis use disorder, was 25 percent higher among teens in states where recreational marijuana is legal compared to states where recreational marijuana isn’t legal.

This means that teens will continue to use pot despite the drug affecting their lives at home, school or work. 

Additionally, among adults older than 26, problematic use was 36 percent higher in states with legalized recreational cannabis.

The team, from New York University School of Medicine, says their findings highlight a potential downside as more states

Medical marijuana is currently legal in 33 states and the District of Columbia.

Eleven of those states – Alaska, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont and Washington – and DC have also legalized recreational use.

Critics have bemoaned that legalizing marijuana in any form will pose a significant public health threat- especially to children and teenagers – while proponents say teens will be less likely to abuse a drug they can easily get their hands on.

For the new study, published in JAMA Psychiatry, the team recruited more than 505,000 participants’ data from the National Survey on Drug Use and Health.

Researchers specifically looked at data from Colorado, Washington, Alaska, and Oregon, the first four states to legalize marijuana for recreational use.

They looked at marijuana use in the past month, and cannabis use disorder over the past year, between 2008 and 2016.

Cannabis use disorder is described with symptoms such as increased tolerance to cannabis, craving the drug, withdrawal when quitting, and using pot despite social or relationship problems.

A 2016 study found that, around the world, an estimated 22.1 million people suffer from cannabis dependence.  

Results of the new study found that, among teens between ages 12 and 17, problematic marijuana use was 25 higher in states where cannabis is legalized for recreational use.

However, researchers noted that the increase was small, rising from 2.18 percent in states where the drug is either illegal or only legal for medicinal use to 2.72 percent in legalized states. 

Among adults aged 26 or older, the rate of cannabis use disorder was 36 percent higher in states with legal pot shops.

There was no change in past-month use among teens but, among adults, past-month use in recreational states was 26 percent higher than in non-recreational states.

‘There are, indeed, important social benefits that legalizing marijuana can provide, particularly around issues of equity in criminal justice,’ said lead author Dr Magdalena Cerdá, Director of the Center on Opioid Epidemiology and Policy at NYU.    

‘Our findings suggest that as more states move toward legalizing marijuana for recreational use, we also need to think about investing in substance use prevention and treatment to prevent unintended harms – particularly among adolescents.’ 

For future research, the team said it would like to examine if other factors are increasing pot use among teens aside from legalization, such as higher-potency cannabis products available on the black market.
