Marijuana takes Toll on Memory Later in Life: Study

A new study has come up with findings that certainly do not have good implications for marijuana users. The old anti-drug PSAs from the 80s and 90s have revealed the fact that the use of marijuana in teenage is associated with memory issues later in life.

The study was conducted by researchers from Northwestern University, saying heavy marijuana smokers fall in the category of smoking it daily for around three years. Their findings showed structural abnormalities occurred in the areas of the brain related to working memory.

Heavy marijuana smokers performed badly in memory tasks. Poor memory is something that takes toll on academic performance and day-to-day functioning in general. The worst thing is the fact that those abnormalities show similarities to those associated with schizophrenia.

Matthew Smith is an assistant research professor in psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine. He said, "The study links the chronic use of marijuana to these concerning brain abnormalities that appear to last for at least a few years after people stop using it".

He said there is a need to conduct more researches to figure out effects of marijuana on human brain, especially before decriminalizing marijuana.
