Effects of Marijuana on Mental Health

Mental health, addiction often a dual fight

According to the Journal of American Medical Association, 50 percent of the people who have a severe mental condition also have a substance abuse problem. JAMA also found that 37 percent of alcoholics have a mental illness, as do 53 percent of drug addicts.
When people use marijuana regularly, the drug may reduce thinking, memory and learning functions. Marijuana's effects on these abilities may last a long time or even be permanent. There have also been increases in fatal car crashes due to marijuana use in states like Washington and Colorado that have legalized the practice.

‘Medical’ marijuana is incompatible with mental health promotion

Similarly, it can be anticipated that if introduced, the indications for the  use of medical cannabinoids would expand well outside of the initial indications. Hence, the medical profession cannot justify the use of medical cannabinoids that would be associated with an iatrogenic risk of serious adverse psychological events.  The use of medical cannabinoids for any purpose, including research under closely observed conditions, is incompatible with mental health promotion.

Marijuana use for medical conditions is an issue of growing concern. Some Veterans use marijuana to relieve symptoms of PTSD and several states specifically approve the use of medical marijuana for PTSD. However, controlled studies have not been conducted to evaluate the safety or effectiveness of medical marijuana for PTSD. Thus, there is no evidence at this time that marijuana is an effective treatment for PTSD. In fact, research suggests that marijuana can be harmful to individuals with PTSD.

Increased availability and decreased perception of harm drive youth use and lowers the age of initiation to drug use — the goal of an industry working to capture lifetime customers, despite known consequences for physical and mental health.  Youth exposures double the risk of addiction.

Review finds ‘significant link’ between cannabis use and onset of mania symptoms

Dr Marwaha said: "The observed tendency for cannabis use to precede or coincide with rather than follow mania symptoms, and the more specific association between cannabis use and new onset manic symptoms, suggests potential causal influences from cannabis use to the development of mania. It is a significant link."

Medical Marijuana: The State of the Science

Medical cannabinoids are here to stay, but intellectual honesty is imperative if we are moving toward exploiting their potential benefits. Owing to rising THC concentrations of products, "medical" marijuana is rarely good medicine.

Marijuana is the most commonly used illegal drug in America: approximately one in 10 adult Americans report having used marijuana in the past year.

Heavy, Frequent Cannabis Use Linked to Mental Illness

A new study suggests people with mental illness are more than seven times as likely to use marijuana weekly than people without a mental illness.

In total, 4.4 percent of individuals with a mental illness in the past 12 months reported using cannabis weekly, compared to 0.6 percent among individuals without any mental illness.

The Teen Brain and Marijuana

Even after controlling for the confounding effect of mental illness symptoms preceding marijuana use, these studies showed an increased risk of developing schizophrenia or mood disorders (depression, anxiety) in adulthood if individuals regularly smoked marijuana during adolescence. The risk was particularly heightened if there was any family history of mental illness (i.e., “genetics provided the loaded gun and marijuana pulled the trigger”). Also, mental illness, among those at risk, tended to show up earlier with marijuana use.
