Leaders of the Parents Movement of the late 1970s and 1980s feared their children’s pot use led to apathy, lower grades and other drugs. The old concerns remain, but the new anti-pot Parents Movement warns more about the fact that marijuana may lead to severe forms of mental illness. A new study confirms that teen marijuana use increases depression and the risk for suicide in young adulthood.
According to the study, the odds of developing depression are 37% higher in young adults up to age 32 who used marijuana as teens, compared to those who did not. The odds of a young adult thinking about suicide were 50% higher in those who smoked pot as teens. The odds of a suicide attempt were almost 3.5 times higher in the pot smokers versus those who didn’t use marijuana.

A significant chunk of marijuana users experience psychotic symptoms. Psychotic killers with mental illness may appear different from political and religious killers, but they often share the trait of persistent, early marijuana use.
In 2014, Washington State high school student Jaylen Fryberg shot five friends whom he had invited to eat lunch with him. On Twitter he revealed the need to smoke a ton of pot because of a breakup. The girl who had broken up with him said on Twitter that smoking pot made him stupid. He was only 15 at the time, but Washington State started selling commercialized pot about four months earlier.
Another pair of high school shooters, the Columbine shooters, chose to do their rampage on 4/20, a symbolic date for junkies. Timothy McVeigh also chose this day for the Oklahoma City bombing.
Were the DC Snipers, John Allen Muhammed and Lee Boyd Malvo, pot users? They fit into a pattern of an older man using marijuana to control a teenager. Before ending up in the DC area, they moved between places known for marijuana: Jamaica, Antigua, Bellingham, Tacoma.
When Marijuana Psychosis Leads to Violence: Aurora, Arizona
Some the most notorious recent murderers who were marijuana users fell victim to psychosis and delusion: Aurora shooter Holmes, Tucson shooter Loughner, Planned Parenthood shooter Robert Dear and Eddie Routh. Routh shot “American Sniper” Chris Kyle and Chad Littlefield because of his paranoia. He smoked marijuana the day of the murders. Suffering from PTSD, he thought the other men would hurt him.
The 15% or so of marijuana users who experience psychotic symptoms from marijuana or go into permanent psychosis (schizophrenia) are 9x more likely to become violent than schizophrenics whose illness has nothing to do with drugs. *
Educating about the connection between drug use and violence with an eye on drug prevention could alleviate much violent crime.
Solution to Cutting Down Mass Violence
Americans argue over the most effective means to stop mass killers.
Discussions often leave out one of the most important components of violence……compulsive drug use, especially marijuana. Let’s consider that the root of violence goes much deeper than a person’s religion, gun laws or innate mental illness. Let’s stop legalizing drugs.
We acknowledge that not everyone who uses marijuana becomes mentally ill or psychotic. However, cannabis use, especially in young users can cause extraordinary changes to the brain. Read how Salman Abedi changed from a cannabis smoking teen to an Isis terrorist.
by SAM (Smart Approaches to Marijuana) Smart Approaches to Marijuana’s 2017 publication references academic studies which suggest that marijuana primes the brain for other types of drug usage. Here’s the summary on that subject from page 4, Marijuana and Other Drugs: A Link We Can’t Ignore :
MORE THAN FOUR in 10 people who ever use marijuana will go on to use other illicit drugs, per a large, nationally representative sample of U.S. adults.(1) The CDC also says that marijuana users are three times more likely to become addicted to heroin.(2)
And according to the seminal 2017 National Academy of Sciences report, “There is moderate evidence of a statistical association between cannabis use and the development of substance dependence and/or a substance abuse disorder for substances including alcohol, tobacco, and other illicit drugs.”(3)
RECENT STUDIES WITH animals also indicate that marijuana use is connected to use and abuse of other drugs. A 2007 Journal of Neuropsychopharmacology study found that rats given THC later self administered heroin as adults, and increased their heroin usage, while those rats that had not been treated with THC maintained a steady level of heroin intake.(4) Another 2014 study found that adolescent THC exposure in rats seemed to change the rodents’ brains, as they subsequently displayed “heroin-seeking” behavior. Youth marijuana use could thus lead to “increased vulnerability to drug relapse in adulthood.”(5)
National Institutes of Health Report
The National Institutes of Health says that research in this area is “consistent with animal experiments showing THC’s ability to ‘prime’ the brain for enhanced responses to other drugs. For example, rats previously administered THC show heightened behavioral response not only when further exposed to THC, but also when exposed to other drugs such as morphine—a phenomenon called cross-sensitization.”(6)
ADDITIONALLY, THE MAJORITY of studies find that marijuana users are often polysubstance users, despite a few studies finding limited evidence that some people substitute marijuana for opiate medication. That is, people generally do not substitute marijuana for other drugs. Indeed, the National Academy of Sciences report found that “with regard to opioids, cannabis use predicted continued opioid prescriptions 1 year after injury. Finally, cannabis use was associated with reduced odds of achieving abstinence from alcohol, cocaine, or polysubstance use after inpatient hospitalization and treatment for substance use disorders” [emphasis added].(7)
Moreover, a three-year 2016 study of adults also found that marijuana compounds problems with alcohol. Those who reported marijuana use during the first wave of the survey were more likely than adults who did not use marijuana to develop an alcohol use disorder within three years.(8) Similarly, alcohol consumption in Colorado has increased slightly since legalization.
