Heavy Marijuana Use Linked to Memory and Learning Deficits
It is well known that the use of drugs and alcohol have devastating effects, not only on the individual who is involved with using, but also on the family. The following study validates the assertion that long-term marijuana use has damaging effects on the mind. The analysis follows a group of users who consume the drug at least four days a week over a five-year period:
“PATRAS, Greece, March 13 – Heavy marijuana use for five years or more may impair memory and slow cognitive function, according to researchers here.
Compared with controls, persons who used marijuana at least four days a week had lower scores on a standardized test of verbal learning skills and were generally “slow learners,” Lambros Messinis, Ph.D., and colleagues of University Hospital Patras reported in the March 14 issue of Neurology.
Moreover, while the impairment was greater among long term users — those who regularly used marijuana for at least 10 years — it was also evident among those who used for only five years, they wrote.”
