A survey published last week showed teenagers who consume methamphetamine (speed) and MDMA (ecstasy) are more likely to experience depressed afterward.
The study, published April 19 in Journal of Epidemiology and Community Health, demonstrated signs of depression were prevalent in users of the drug — even a year after use.
The survey included 3,900 10th Canadian graders, who were given survey questions over the course of a year. Those who admitted to use had a 60 to 70 percent higher risk of experiencing depression symptoms a year after they said they used the substances than their peers.
Drug-related depressive symptoms were noted independently of non-drug related depression, indicating the validity of the study's results.
"This doesn't ensure causality, but that's the closest we can get with this kind of study," study co-author Dr. Jean-Sebastien Fallu, associate professor of educational psychology at the University of Montreal told CNN.
