Marijuana may already be practically legal in most of the United States, but its improved legal status there does not mean its effects on users have become any less adverse. A long-running study conducted by a university in Switzerland reveals that marijuana use over a long period of time may affect one’s verbal memory, says a report by Vanessa Brown for News.com.au.
Long-term marijuana use study spanned 25 years
The study led by Professor Reto Auer from the University of Lausanne spanned 25 years. More than 3,500 Americans acted as participants in the study, which was published in the JAMA Internal Magazine. The results were particularly worrisome, especially for those who continued to use the drug 25 years later.
According to the study, there is a clear link between long-term marijuana use and poorer performance on verbal memory tests. A user would remember one less word from a list of 15 with every additional five years of smoking pot, the research reveals
While this may not sound that alarming to most people, “any impact on a person’s cognition is concerning”, according to Dr Peter Gates, senior research officer at the National Cannabis Prevention and Information Centre.

Results not really surprising
Before the study came out with its conclusions, we already have an idea how much cannabis can affect one’s memory and verbal ability. Not a few among us have known people who actually use pot, some quite more heavily than others. More often than not, we have seen them in a state of being spaced out. They’re also likely to mumble, which we often attribute to their being high on the substance.
Now imagine if that person smoked pot every day for the next five years. To be honest, we think a diminished verbal memory is only the tip of the iceberg as far as long-term effects of marijuana use are concerned.
