More frequent use of marijuana damages brain working memory, which can cause problems with safety, communication and success of work, a new study Found
“Working memory has the ability to maintain and use information for a short term,” said Joshua Govin, Assistant Professor of Radioliji at the University of Colorado, Colorado, Colorado.
“An example of this is checking your blind location while walking on the road,” said Govin. “When you look back in front of you, you will need to remember what you saw in the Blind spot before you can make a good decision if you want to change the streets.
“When you are in the middle of a conversation with your boss, you need to remember that he said too long to answer it.” “Losing working memory means that more efforts may need to be kept and more difficult to maintain this information.”
Only a connection, cause and effect not
New observance study, Appeared on Tuesday At the Journal Jama Network Open, can not prove that cannabis is damaged by the brain, said Carol Bid, the founder of the Center for Drugs, Alcohol, Smoking and Health Studies at Michigan University in Professor Emerita and Narber. She was not involved in this study.
However, this study included scientific evidence in the long -standing social beliefs of the regular use of Bang, Bid said in an email.
“For years, physicians, family and friends who knew heavy heavy heavy -henching understand that their memories have ‘shot’ – there is also a term for this, as ‘stoner’, as ‘gruzed’ Forgot the list, could not follow a prescription, could not do, he said, ‘Tea will not gather it’.
However, the study could not determine if the working memory returns, if a heavy user leaves and is a non -user for the extended period.
“Did the young young people use hemps more than 1000 times between the ages of 15 and 20, but stopped using it 20 years later, showing better memory to work after 10 years?” Bid said via email. “This is my $ 64 question-where is the hope for a person with a malfunction of a malfunction who wants his memory back?”
This study analyzed the data Human Connectum Project, The study collects raw data that focuses on how age, development, disease and other factors affect the brain.
In which researchers call the largest datastate used to study hemp and brain function, more than a thousand existing or current hemp users have made brain scanned by completing seven different types of academic tests between 2012 and 2015. –
These tests measured their working memory, how they used emotions and rewards in their thinking, and what the brain responded to the language. In addition, researchers experienced how the brain handled the motor skills, as well as how each person’s brain responded to others in the social environment.
Study participants, aged between 22 and 36 years, provided urine samples on testing days to evaluate recent use. This can be detected, “for 2 weeks in a casual user and potentially chronic user”, which provides the enthusiasm associated with the use of hemp, or THC, or THC, which provides the enthusiasm associated with the use of hemp. American centers to control and prevent diseases.
Individuals were considered heavy users of cannabis if they used marijuana more than a thousand times in their lives. Moderate users if they used grass between 10 and 999 times. And if the nonsers were less than 10 times their use.
Researchers found that Bang used to reduce mental activity in some areas of the brain that were responsible for decision -making, memory, attention and emotional processing. However, the only test memory to reach the importance of data was, such as remembering the purchase list or following verbal instructions.
Researchers found that 63 % of the heavy lifetime canabis consumers showed low brain activity during working memory work, while 68 % of people who experienced positively for the use of recent cannabis who have similar effects. Demonstrated.
“However, when we recently compared chronic customers of cannabis, we found that when working memory difficulties, chronic use than recent use, more important than recent use It seems. ”
He said that the reduction of brain activation for heavy consumers compared to non -consumers was about 14 %.
This study did not know the timeframe for heavy heavy use – was it all of these 1,000 uses in the early 20s of the 20s and then avoided for 10 years? Or did they become recent heavy users?
He said, even if a permanent user has stopped using it, he has shown academic deficiency in working memory. “” So it didn’t look like it was a consistency on recent use, but it was more related to their chronic use throughout their lifetime. ”
Arrogant questions.
In this study heavy heavy consumers were masculine, with less academic and social economic status, and more likely to smoke and drink alcohol.
“However, we added alcohol to our statistics models, and we have learned that alcohol did not specify their effects in which we saw, while the use of cannabis was used.”
However, this study was unable to determine the level of THC in marijuana, which was known or controlled for existing psychological conditions like ADHD, known as. Effect on working memory, Bid said.
He added, “It is possible that ADHD is a confidential, which distorts the results between heavy heavy use and poor working memory.” Young adult adults are represented inappropriately represented by the hemp. –
“The amount of THC entered, and the infusion method was not provided,” said Bid, so there is no way to know how to know how much is ThC is involved in chronic, heavy use. ”
Although it is true that researchers were unable to determine whether Bhang was smoking, Wapd or eating, the study was conducted before 2015 when smoking was the most common, Gwan said.
“And certainly smoking or breathing means that it crosses the blood brain obstruction more rapidly if you use the edible,” he said.
So what is the answer to the 64 64 question of the bid: Will Bhang users return their working memory regularly? Gwen said he was still known very quickly.
“Some really interesting studies have paid people Stop the use of hemp For some time, there is usually a month, and there is some evidence that they recover some of their memory ceremonies during this time.
“And there is some evidence that the abstinence of alcohol can lead to recovery of mental tissue,” Gwon added. “But when it comes to the use of chronic hashish and the brain, it is an area in which the investigation is underway. We just don’t know.”
