New study finds connection between early use of marijuana and mental illness

The Wall Street Journal reports.

Excerpt:

There is a significant and consistent relationship between marijuana use and the development of schizophrenia and related disorders. Schizophrenia is considered by psychiatrists to be the most devastating of mental illnesses. Patients who suffer from it often experience auditory or visual hallucinations, severe social withdrawal and cognitive impairment. Many require frequent and prolonged hospitalization in psychiatric wards.

Schizophrenia affects almost three million Americans—more than six times the number of people with multiple sclerosis, two and a half times the number of people with Parkinson’s disease, and more than twice the number of people with HIV/AIDS. Less than one-third of patients with schizophrenia can hold a steady job or live independently. A large portion (about one-third) of homeless people in the U.S. suffer from the disease.

Though they receive little attention in the legalization debate, the scientific studies showing an association between marijuana use and schizophrenia and other disorders are alarming. A 2004 article in the highly respected British Journal of Psychiatry reviewed four large studies, all of which showed a significant and consistent association between consumption of marijuana (mostly during teenage years or early 20s) and the later development of schizophrenia. The review concluded that marijuana is a “causal component,” among others, in the development of schizophrenia and other psychotic disorders.

A 2007 study in the Lancet, a British medical journal, concludes that using marijuana increases the risk of young people developing a psychotic illness, such as schizophrenia. This risk is greatest—up to a 200% increase—among those who use marijuana heavily and who start using at a younger age.

I thought this article was useful for parents who need some ammunition when talking to their children about drugs. Children can be pretty irrational. You show them studies, and they say “that will never happen to me”. That’s just how they are. But at least when you show them the evidence, it might stick in their mind a little more. It’s all in the way you present it, I think. The idea is to be truth-focused and authentic, rather than confrontational. Maybe discuss it as a policy issue rather than a parenting issue.

  1. I must add that the legalization of pot has long been a sought-after nirvana of the Left and many social libertarians.
