Largest brain study of 62,454 scans identifies drivers of brain aging
05/01/2019

The study found that a number of brain disorders and behaviors predicted accelerated aging, especially schizophrenia, which showed an average of 4 years of premature aging, cannabis abuse (2.8 years of accelerated aging), bipolar disorder (1.6 years accelerated aging), ADHD (1.4 years accelerated aging) and alcohol abuse (0.6 years accelerated aging). Interestingly, the researchers did not observe accelerated aging in depression and aging, which they hypothesize may be due to different types of brain patterns for these disorders.

Carol Falkowski: Marijuana and adolescents: Caution
03/05/2017

Everyone should be concerned:  Voters, not medical practitioners or scientists, have been able to determine medical practice.
Beneath it all, however, we must pause to seriously consider the known, detrimental effects of repeated marijuana use on the developing adolescent brain.  We must act accordingly and responsibly in ways that promote the public health and safety, help delay initiation of use, and reduce, not increase, the accessibility of marijuana to this particularly vulnerable population.

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].

Marijuana use in early adolescence may affect verbal IQ
01/24/2017

"The study suggests that the effects of cannabis use on verbal intelligence are explained not by neurotoxic effects on the brain, but rather by a possible social mechanism," said lead author Natalie Castellanos-Ryan, Assistant Professor at Universite de Montreal in Canada

Parsing the Contradictions: Marijuana and the Brain
12/07/2016

“We see specific morphological changes in the brain to important neurotransmitter systems, and individuals who are exposed to THC early in life show greater sensitivity to opiates than others do,” she said. “We know that the brain definitely adapts to marijuana. It is profoundly changing the receptors and receptor signaling that impact gene expression. And the changes it makes last through adulthood and even into the next generation. So we see that there’s something about the ongoing processes in the developing brain that this drug somehow sensitizes—in the cells, the receptors, and in the signaling cascades—that makes kids more vulnerable to addiction and other problems later.”

“There is a lot of optimism for what components of the marijuana plant may offer on a medicinal level but, like all other drugs, the caveat is that you have to know what it does, what population it can be used for, and who could be vulnerable to its effects. We need a lot more research before we can say anything concrete about its future as a treatment.”

Cannabis use during pregnancy may affect brain development in offspring: Thicker prefrontal cortex
06/20/2016

Summary: Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study. Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.

Adolescent Cannabinoid Exposure Induces a Persistent Sub-Cortical Hyper-Dopaminergic State and Associated Molecular Adaptations in the Prefrontal Cortex
01/04/2016

Thus, adolescent THC exposure induced behavioral abnormalities resembling positive and negative schizophrenia-related endophenotypes and a state of neuronal hyperactivity in the mesocorticolimbic dopamine (DA) pathway. Furthermore, we observed profound alterations in several prefrontal cortical molecular pathways consistent with sub-cortical DAergic dysregulation. Our findings demonstrate a profound dissociation in relative risk profiles for adolescent versus adulthood exposure to THC in terms of neuronal, behavioral, and molecular markers resembling neuropsychiatric pathology.

Study: High-potency marijuana linked with neural damage
11/28/2015

"We found that frequent use of high-potency cannabis significantly affects the structure of white matter fibres in the brain, whether you have psychosis or not," 
The main psychoactive ingredient in weed, tetrahydrocannabinol (THC), is much more concentrated in modern skunk strains as compared to traditional pot and hash -- up 14 percent as compared to 4 percent.

Everyone Praises the Healing Power of This Drug—but Many Don’t Realize the Damaging Effect It Has on Teens
09/12/2015

In 2014, Gilman published research on 18-to-25-year-olds that showed differences in the brain’s reward system between users and nonusers. Teens who smoked marijuana had significant abnormalities in the areas of the brain linked to emotion, motivation, and decision-making (see diagram above). “I got a lot of hate mail after that,” she says.

Medicinal and Recreational Marijuana: What are the Risks?
07/31/2015

Brain abnormalities and memory problems were observed in these individuals in their early twenties, two years after they had stopped using marijuana. The cannabis users were noted to have striatal, globus pallidus, and thalamus changes showing these brain regions appearing to shrink and collapse inward. These individuals also had poorer working memory. The earlier the age of cannabis use, the more dramatic the brain changes and memory deficits were noted to be.
Not only does it appear that cannabis use itself is a potential precursor to future drug use, but the age of first use of cannabis and the frequency of cannabis use seem to also be predictors of future substance abuse issues. Studies have shown that over two-thirds of those under the age of 18 who have been admitted to a drug treatment program identify cannabis as their substance of choice.
” One important characteristic that defines a substance use disorder is “an underlying change in brain circuits that may persist beyond detoxification, particularly in individuals with severe disorder"

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.

“It’s a natural plant! What’s the big deal?” —A common declaration among youth who believe that the effects of marijuana are harmless and that the substance shouldn’t be regulated.  Regardless of public opinion, the science is clear:  Regular recreational use of marijuana during adolescence is harmful to the brain, which isn’t fully developed until the age of 25.

Brain Facts- Society of Neuroscience
02/16/2012

In radioactive tracing studies, scientists found that tetrahydrocannabinol (THC), the active ingredient in marijuana, binds to specific receptors called cannabinoid receptors, many of which coordinate movement. This may explain why people who drive after they smoke marijuana are impaired. The hippocampus, a structure involved with memory storage and learning, also contains many receptors for THC. This finding provides some insight into why heavy users or those intoxicated on marijuana have poor short-term memory and problems processing complex information.

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.
