Here’s something pot-using teens should remember: Swearing off marijuana may improve memory. better at acquiring and storing new information compared to their counterparts who persist in the pot puffing.

“This study provides convincing evidence that adolescents and young adults may experience improvement in their ability to learn new information when they stop using cannabis.”

The study comes as fully legalized marijuana use is taking root in some parts of the U.S. and nationwide in Canada. Recreational marijuana use is legal for ages 21 and up in the district of Columbia and nine states, including Massachusetts.

Other states, including New Jersey, are eyeing full legalization. Medical marijuana is legal in another 22 states, as doctors note the drug’s benefits for conditions like chronic pain and glaucoma. Canada legalized use of recreational marijuana on Oct. 17.

Meanwhile, cannabis companies are also getting a lot of investor these days – even with the market recently having a good buzz. Monday capped another tough day for cannabis companies including Aurora Cannabis

Those who maintained abstinence learned more than those who continued to use cannabis.

“In this era of widespread cannabis legalization, we need to be mindful of more prevention programs for adolescents and young adults,” Randi Schuster, the study’s lead author, told MarketWatch. The study noted that two years ago high school senior perceptions of regular marijuana use as harmful “at or near historic lows.”

Schuster, an assistant professor of psychiatry at Harvard Medical School, and senior author A. Eden Evins noted that the research focuses on a critical time in a person’s life, while their brain is still maturing and they are going to school.

Evins, a psychiatry professor at Harvard Medical School, said the study included “weekend users” who might be under the impression that a hazy Saturday night didn’t matter for an upcoming test. “That may not be the case,” Evins said. “They may be okay for the test in a week’s time.”

The authors said the study was the first of its kind to examine whether cognitive improvement happened with abstinence, and when that improvement happened. “What we found was surprising,” said Schuster. There was a lot of improvement in just one week, the study found.

The countless differences were found in participants’ ability to absorb new information, like a broader vocabulary.

The tell-tale differences were found in participants’ ability to absorb new information, like a broader vocabulary. “Those who maintained abstinence learned more than those who used to use cannabis,” the study said.

Experiments acknowledged they lacked a non-control group to measure the improvements. A broader version of the experiment is planned, using 13- to 19-year-olds and a control group comprised of people, Schuster said.

The forthcoming study will look into memory and attention, but also other mental tasks like decision- making, she noted. Including a non-using control will help researchers determine if abstinence returns certain cognitive tasks back to normal baseline, Schuster said Findings are expected in about a year

The newly-released study noted marijuana is thought to impact brain maturation through tetrahydrocannabinol (THC). THC is the chemical that causes the user’s high and the study involved changes in THC levels.

But there is a whole other angle to the budding cannabis market, and its effects are still being studied as well. Another component of marijuana is cannabidiol, which reportedly helps with anxiety and inflammation without any high. The CBD market is estimated to grow to $ 2 billion by 2020.
