Smoking cannabis before the age of 15 could lead to insomnia later in life, a new study has found.
Researchers in the US discovered any history of using the drug was associated with an increased risk of reporting difficulty getting enough sleep.
Participants in the study reported struggling to fall asleep, difficulty maintaining sleep, experiencing non-restorative sleep and feeling sleepy during the day.
Scientists at the University of Pennsylvania in Philadelphia found the strongest association in adults who used cannabis before the age of 15.
“Current and past marijuana users are more likely to experience sleep problems,” said lead author Jilesh Chheda, research assistant at the University of Pennsylvania in Philadelphia, working with Dr. Michael Grandner, the senior author on the study.
