New research published today in the journal JAMA Internal Medicine confirms what many of us have suspected for some time: If you smoke a lot of weed -- like a lot of it -- it can potentially do permanent damage to your short-term memory.
Professor Reto Auer of the University of Lausanne led a team of researchers who examined data on the marijuana habits of nearly 3,400 Americans over a 25-year period. At the end of the study period, the subjects took a battery of tests designed to assess cognitive abilities -- memory, focus, ability to make quick decisions, etc.
The study found that people who smoked marijuana on daily basis for a long period of time -- five years or more -- had poorer verbal memory in middle age than people who didn't smoke, or who smoked less. This association remained even after researchers controlled for a variety of other factors known to affect cognitive performance -- such as age, education, use of other substances and depression.
Auer and his team measured lifetime marijuana exposure in a fantastic new unit of measurement they call "marijuana-years." Essentially, if you smoke pot every day for a year, that equals one marijuana-year of use. Ditto if you smoke every other day for two years, or once a week for seven years.
