Title
Massive Danish study finds strong link between marijuana addiction and mental illness
03/23/2023

The study, published May 4 by the Cambridge journal Psychological Medicine, examines 6.9 million people ages 16-49 and more than 45,000 schizophrenia cases from 1972 to 2021. It found that the adjusted incidence risk ratio for males ages 16 to 20 was more than twice that for females of the same age group, concluding that “[a]t a population level, assuming causality, one-fifth of cases of schizophrenia among young males might be prevented by averting CUD” (cannabis use disorder).

We need to talk about marijuana’s potential harm to youths
10/14/2022

One study shows nearly half of college students said they consumed marijuana. Eight percent reported they used it daily or nearly every day. One in 5 high school students used marijuana in the preceding 30 days.

But there are real dangers associated with the substance, as a 2020 report from the National Institute on Drug Abuse (NIDA) showsAbundant research demonstrates how exposure to marijuana during childhood impacts later cognitive ability, including memory, attention, motivation and learning. Studies have linked regular cannabis use in adolescents with lower IQs in adulthood and higher propensity to drop out of high school. This association persists in college-age students. One large study followed college students and found frequency of marijuana use to correlate with skipping classes, lower grade-point average and longer time to graduation.

Adolescent cannabis use and later development of schizophrenia: An updated systematic review of longitudinal studies
01/01/2022

Both high- and low-frequency marijuana usage were associated with a significantly increased risk of schizophrenia. The frequency of use among high- and low-frequency users is similar in both, demonstrating statistically significant increased risk in developing schizophrenia.

The link between pot and mass shootings may be closer than we think
08/15/2019

Just last year, the Parents Opposed to Pot lobby group tried to sound the alarm on the link between marijuana and mass shootings, compiling a list of mass killers it claims were heavy users of marijuana from a young age, from Aurora, Colo., shooter James Holmes and Tucson, Ariz., shooter Jared Loughner to Chattanooga, Tenn., shooter Mohammad Abdulazeez.
You can’t address the youth mental health crisis without considering the effect of rising teen marijuana use.
Among American teenagers, the drug’s “daily use has become as, or more, popular than daily cigarette smoking” according to the National Institute of Health’s 2017 Monitoring the Future study.
Another BMJ study estimated that “13 percent of cases of schizophrenia could be averted if all cannabis use were prevented.” That’s more than 400,000 Americans who could be saved from a fate worse than death.

High Potency Marijuana "Strongly Linked" to Psychosis
03/13/2019

It is the latest in a long line of evidence that marijuana is not an innocent relaxation drug. “Smoking high-potency cannabis, used daily, has been linked to diagnosis of conditions like schizophrenia, paranoia and other psychosis disorders, new findings say. About 50 percent of new cases of psychosis disorders diagnosed in Amsterdam were linked to use of high-potency cannabis, according to a study published Tuesday in The Lancet.

Review of the public health risks of widespread cannabis use
04/08/2018

1. Legalizing cannabis has been shown to increase the rates of motor vehicle accidents.
2. Cannabis use is a risk factor for mental illness.
3. Inhaled Cannabis use is a risk factor for respiratory infections.
4. Cannabis use increases the rate of vascular disease. Cannabis is the third most often identified drug of abuse
5. Cannabis use during pregnancy has been associated with increased risk of adverse birth outcomes
6. Legalization of cannabis has been shown to increase cannabis exposure in the pediatric population.
7. Heavy cannabis use is associated with diminished lifetime achievements.
Doctors must educate the public about the potential harm cannabis causes with heavy, and possibly moderate, widespread use just as they do about the dangers of tobacco use. Tobacco use has declined in the United States in large part because of the knowledge the public now holds about its adverse effects, as opposed to legislative action.

Mental health, addiction often a dual fight
06/05/2017

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
04/20/2017

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.

Learn more about the risks marijuana use poses to your health.
01/29/2017

Here are just a few of the health effects you may want to know:

  • Marijuana use directly affects the brain—specifically the parts of the brain responsible for memory, learning, and attention.
  • The compounds in marijuana can affect the circulatory system and may increase the risk of heart attacks and strokes.
  • Smoking marijuana can lead to a greater risk of bronchitis, cough, and phlegm production.
  • Marijuana users are significantly more likely than nonusers to develop chronic mental disorders, including schizophrenia. Schizophrenia is a type of mental illness where people might see or hear things that aren't really there (hallucinations).
  • Eating foods or drinking beverages that contain marijuana have some different risks than smoking marijuana, including a greater risk of poisoning.
  • About 1 in 10 marijuana users will become addicted. For people who begin using before the age of 18, that number rises to 1 in 6.
  • Some research shows that using marijuana while you are pregnant[288 KB] can cause health problems in newborns—including low birth weight and developmental problems.
  • Marijuana use can slow your reaction time and ability to make decisions when driving[271 KB].

Health Effects of Marijuana and Cannabis
01/20/2017

The evidence reviewed by the committee suggests that cannabis use is likely to increase the risk of developing schizophrenia, other psychoses, and social anxiety disorders, and to a lesser extent depression.   Heavy cannabis users are more likely to report thoughts of suicide than non-users, and in individuals with bipolar disorder, near-daily cannabis users show increased symptoms of the disorder than non-users.

Marijuana Violence and Law
01/17/2017

According to research studies, marijuana use causes aggressive behavior, causes or exacerbates psychosis and produce paranoias. These effects have been illustrated through case studies of highly publicized incidents and heightened political profiles.

Marijuana is currently a growing risk to the public in the United States. Following expanding public opinion that marijuana provides little risk to health, state and federal legislatures have begun changing laws that will significantly increase accessibility of marijuana. Greater marijuana accessibility, resulting in more use, will lead to increased health risks in all demographic categories across the country. Violence is a well-publicized, prominent risk from the more potent, current marijuana available.

Marijuana Use and PTSD among Veterans
06/05/2015

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.

“Pot used to be pretty harmless, but it’s plenty dangerous today”
05/24/2015

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
02/10/2015

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
02/06/2015

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. This review has identified the dangers associated with whole­plant marijuana, whether used for recreational or for supposedly medical purposes.

Marijuana and Mental Illness
07/30/2014

Marijuana is the most commonly used illegal drug in America: approximately one in 10 adult Americans report having used marijuana in the past year. In recent years, laws addressing the use and possession of marijuana have been changing, and many states—including Colorado, California, Massachusetts and others—have passed regulations either legalizing marijuana for medical purposes or decriminalizing the non-medical use of marijuana. While different groups of professionals have had varied responses to the implications of this new legislation, mental health professionals have been largely united in expressing their concerns of the negative impact marijuana has for people with mental illness. Furthermore, the scientific data is clear that regular marijuana abuse is linked with increased risk of legal troubles and jail time, difficulties at school and at work, as well as abuse of alcohol and other drugs.

Heavy, Frequent Cannabis Use Linked to Mental Illness
04/03/2014

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.

Cannabis use disorders occurred among 4 percent of those with mental illness versus 0.4 per cent among those without.

Researchers also noted that, although cannabis use is generally higher among younger people, the association between mental illness and cannabis use was pervasive across most age groups.

The Teen Brain and Marijuana
02/16/2012

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.
