(KTVI) – A new study link marijuana use at a young age to a decline in intelligence in adulthood. Basically, smoking pot as a teenager can literally make you dumb. Researchers at Duke University measured the I-Q’s of 13 year old’s before marijuana use and then again at 38 years old after years of smoking pot.
They found an average of an 8 point decline in intelligence levels. Researchers think teenagers brains are not fully developed and are more susceptible to the adverse impact of marijuana.
