New study: teen pot use could hurt brain and memory

Teenage pot smokers could be damaging brain structures critical to memory and reasoning, according to new research that found changes in the brains of heavy users.

Research released Monday in the journal Schizophrenia Bulletin showed the brains of young heavy marijuana users were altered in so-called sub-cortical regions — primitive structures that are part of the memory and reasoning circuits. And young people with such alterations performed worse on memory tests than non-using controls, despite the fact that the heavy users had not indulged for more than two years, on average, before the testing.

“We see that adolescents are at a very vulnerable stage neurodevelopmentally,” said Matthew Smith, who led the research team at Northwestern University Feinberg School of Medicine in Chicago. “And if you throw stuff into the brain that’s not supposed to be there, there are long-term implications for their development.”

The portion of people ages 12 to 17 who used marijuana during the past month fell to 9.5 percent last year from almost 12 percent in 2002, according to the latest figures from the government’s Substance Abuse and Mental Health Services Administration. But that still represents millions of adolescents and teenagers — and the legalization of marijuana has raised the specter that underage people will have easier access.

Adults who smoked pot regularly as teens were shown to have “neuropsychological decline” and “more cognitive problems” than non-users in a study last year in the Proceedings of the National Academy of Sciences (PNAS). This was true even if users stopped using long before the study.

I think these papers are useful when talking to young people about drugs. You don’t want it to be a situation where you are ordering them around based on nothing more than YOUR needs and YOUR beliefs. Then it turns into a head-butting contest, and you can’t watch them all the time. A better alternative is to produce the studies that show the real effects and then ask them what they have on their side. If they are going to rebel anyway, at least you have tried to persuade them rather than control them, and that’s good parenting.

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.

New study: belief in God can significantly improve mental health outcomes

Excerpt:

A new study suggests belief in God may significantly improve the outcome of those receiving short-term treatment for psychiatric illness.

Researchers followed patients receiving care from a hospital-based behavioral health program to investigate the relationship between patients’ level of belief in God, expectations for treatment and actual treatment outcomes.

In the study, published in the current issue of Journal of Affective Disorders, researchers comment that people with a moderate to high level of belief in a higher power do significantly better in short-term psychiatric treatment than those without.

“Belief was associated with not only improved psychological well-being, but decreases in depression and intention to self-harm,” says David H. Rosmarin, Ph.D., an instructor in the Department of Psychiatry at Harvard Medical School.

The study looked at 159 patients, recruited over a one-year period. Each participant was asked to gauge their belief in God as well as their expectations for treatment outcome and emotion regulation, each on a five-point scale.

Levels of depression, well-being, and self-harm were assessed at the beginning and end of their treatment program.

Obviously, the issue of God’s existence is a matter to be decide based on what is true and false, but this kind of story might help us to get motivated for persuasion.
