Smoking cannabis can lead to manic behavior: Hyperactivity, aggression and delusions are all strongly linked with the drug, researchers warn

Madlen Davies, Daily Mail, February 11, 2015

Dr. Steven Marwaha, of Warwick University in the UK, studied over 2,000 people and found a ‘significant link’ between cannabis use and manic behavior: depression, anger, aggression, hyperactivity, difficulty sleeping, being delusional and hearing voices.

The research found that marijuana use “tended to precede or coincide with episodes of mania.”

The study, published in the Journal of Affective Disorders, raises particular concerns about adolescents and the problems cannabis use can have on their development.

Dr. Marwaha said, “Cannabis is the most prevalent drug used by the under-18s. During this critical period of development, services should be especially aware of and responsive to the problems cannabis use can cause for adolescent populations.”

“The findings add to a body of evidence that cannabis may increase rates of mental health problems including depression, anxiety, psychosis and schizophrenia.”
