Scientists have discovered that People who used marijuana from a very young age had lower IQ, highly abnormal brain function in memory, reward processing and self-referential activity areas in brain.

It is the most commonly used illegal drug in the world. According to Dr. Elizabeth Osuch, who is also the Medical Director of the First Episode Mood and Anxiety Program (FEMAP) at London Health Sciences Centre said that

“Marijuana users, especially those who begin at a very young age are at a greater risk for the onset of bipolar disorder, depression, and schizophrenia.

Youth who use marijuana heavily reported that it improves their psychiatric conditions because it makes them feel good momentarily. Due to this reason, he decided to study the effects of depression and marijuana on psychiatric symptoms, and cognitive function and brain function.”

Dr. Osuch and her team divided youth in four groups:

 Individuals with depression who were not using marijuana

Those with depression who were using marijuana frequently

Marijuana users without depression;

And healthy individuals who were not using marijuana at all.

There is no evidence found that marijuana helps in managing depressive symptoms; there was no difference in psychiatric symptoms between those with depression who used marijuana and those with depression who did not use marijuana.

In addition, results showed differences in brain function among the 4 groups in brain areas that are associated to motor control and reward-processing. These findings suggest that using marijuana does not correct the symptoms of depression and using it from an early age may have an abnormal effect not only on brain function, but also on IQ.
