(WHAS11)- Is smoking pot helping to dumb down young people?
Researchers from Duke University found that young pot smokers could have a lower IQ as they get older.
Researchers measured the IQ’s of 13-year-olds before marijuana use, and then measured their IQ’s again at 38-years-old, after years of pot smoking.
They found an average of an eight point decline in intelligence levels.
Those who started smoking as adults did not suffer a decline in intelligence.
Researchers say that is because a teenager's brain is not fully developed and that is why they are susceptible to a bigger impact from pot.
