Sleep Patterns Disrupted by Marijuana Use

iStock/Thinkstock(NEW YORK) -- Marijuana might make some people lethargic but that doesn’t necessarily mean it’s going to help them sleep better.

What’s more, researchers believe that pot can cause sleep problems, especially among long-term users.

The study conducted at the Perelman School of Medicine at the University of Pennsylvania reveals that adults who began smoking marijuana prior to their 15th birthday will be twice as likely to experience major difficulties in getting to sleep as well as feeling tired during their waking hours than those who started smoking later in life.

Lead author Jilesh Chheda says one thing about the study that really stood out was that when it came to sleep problems, the frequency of marijuana use wasn’t nearly as significant as the age that the adults began using the drug.

Chheda adds that although his team wasn’t trying to make a direct link between marijuana and impaired sleep habits, the implications of the study were significant given how many Americans now use the drug.
