Just months after London researchers found the two major chemicals in marijuana serve dueling roles towards mental health — one good and one bad — another group of scientists say their work paints a darker finding.
Those who use marijuana when they are young may be at risk of abnormal brain function and lower IQ, they say.
That’s the finding of a team that included Dr. Elizabeth Osuch, a scientist at Lawson Health Research Institute and medical director of the First Episode Mood and Anxiety Program in London
“Many youth in our program use marijuana heavily and, despite past research, believe it improves their psychiatric conditions because it makes them feel better momentarily,” said Osuch.
