(Mirror Daily) – A new study has revealed that heavy pot use in adolescence is linked to weaker memories. It appears that teens who smoke a lot of pot have poorer memories and also some brain abnormalities than those who smoke less or no marijuana at all. While the study cannot safely say which one came first, the brain abnormalities or the pot use, it is safe to say that heavy pot use does have long-terms effects. The results of the study were published in the journal Hippocampus.

The study was performed by a team of researchers from Northwestern University in Evanston, Illinois. The team followed 97 teenagers with and without mental illness. The teens who smoked weed, said that they had started using the drug at 16 or 17 and that they have been using pot and just pot daily.

After careful examination it was revealed that marijuana users had some brain abnormalities, such as an abnormally-shaped hippocampus, which is the area of the brain used for storing long-term memory. They also performed 18% worse on long-term memory tasks.
