Smoking pot may impair your coordination and other motor skills , even when you ’re not eminent , anew reviewof field notice .
In the review article , researcher found thatpeople who used marijuanahad conflict in mind area called the corticostriatal networks compare with hoi polloi who did n’t use the drug . These area are connected to motor learning and restraint , and can affect people’sreaction clock time , memory , and the ability to swap between tasks , according to studies let in in the review .
The researchers ' review of literature admit 14 study published between 1992 and 2015 that looked specifically at motor role in cannabis users , along with numerous other studies that examined cannabis use in connexion to cognitive office . [ 11 Odd Facts About Marijuana ]
" While we found many inconsistent results between studies , the general consensus back [ the musical theme that there are]cognitive and motor impairments associate with cannabisuse , " said Shikha Prashad , lead author of the critique and a postdoctoral inquiry scientist at the University of Texas at Dallas .
For example , one study , published in the diary Pharmacology Biochemistry and Behaviorin 2002 , look at marijuana user who had fume pot at least seven times per week over the anterior two year , and compared them with the great unwashed who did not habituate marijuana . The study showed thatfrequent marijuana usershad poorer memory than nonusers . Moreover , on PET ( positron expelling tomography ) scans — which utilize a radioactive tracer bullet inject into the pedigree to evaluate natural process in the brain — these Cannabis sativa substance abuser had reduced body process in area ofthe cerebellum , an area of the brain that is linked with motor control , coordination and proportionality , compared with nonusers .
Another study , published in the journal Neuropsychopharmacologyin 2009 , look at people who used marijuana five to seven times a calendar week for at least the prior two long time . The field found that these marijuana users made around the same routine of mistakes as non - marijuana user on a labor where they had to press a push every clock time a word appeared on screen , unless the word was a ) the same parole on the previous slide , or b ) if the news and case did not match . However , the marijuana users were significantly less mindful than the non - marijuana users of any errors made .
In short , when the researchers put all of the findings together , the evidence showed thatmarijuana " may modify the way brainregions process information and communicating , " in a direction that affects people ’s motor control , Prashad secernate Live Science . " These change may be the footing of potential impairments in the processing of cognitive and motor information , " Prashad explained , " thus affecting the ability to check new motor skills . "
The researchers observe that , amazingly , some field of study have found few motor stultification in citizenry who use marijuana regularly than in those who use the drug only sporadically . Prashad said that this may be because continuing employment of the drug leads to serious tolerance of it , or because other brain area begin to compensate for marijuana ’s effects on motor skills , though more research is required to nail these causes .

However , the review revealed that there is a prominent col in research on how marijuana may sham people ’s ability to learn newmotor acquirement , the researchers enjoin . Most inquiry so far has focused on the drug ’s effects on people ’s motor performance in acquirement they already sleep with how to do . " These changes [ in motor performance ] may be the foundation of possible constipation in the processing of cognitive and motor information , " Prashad say . succeeding research should bet at this , she say .
The review noted that many of the work had low sample sizes , as well as a wide-cut variation in player ' habit of the drug , sometimes combining heavy or frequent users of the drug with light or infrequent exploiter . In addition , some studies include participants who may have been using multiple drugs or alcoholic drink , which makes it difficult to relate the cause of specific disablement to cannabis alone , the researchers enunciate .
succeeding enquiry may shed more visible radiation on the connection between marijuana use andmotor eruditeness . For instance , Prashad suggest , some subject area could focus on motor succession learning — the learning of different steps of a new motor activeness , such as walk .
" The motor - learn battlefield is rich with [ estimation ] that can be employ to study the consequence of cannabis use on cognitive and motor processes , " Prashad tell , add that the significance of impairment are of the essence to public wellness and safety .
