A new study links marijuana use at a young age to a decline in intelligence in adulthood, an irreversible decline. 

Basically, pot smoking as teenagers can literally make you dumb.

That is how the lead scientist from Duke University characterized the conclusion of the research. 

Researchers measured the IQ's of 13-year-olds before marijuana use.  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. 

The study also found people who started smoking pot as adults did not suffer any decline in intelligence.
