Whether they use marijuana for recreational or medicinal purposes, people can develop withdrawal symptoms when they stop using it.
Marijuana, or cannabis, is the “most commonly used illicit drug in the United States,” according to the Centers for Disease Control and Prevention (CDC).
In recent years, more states have legalized the recreational and medicinal use of marijuana. However, based on a 2018 survey from Washington State, legalization does not seem to have significantly increased marijuana use. That said, marijuana use has been gaining a lot of attention.
Growing up, I had the picture-perfect family. I lived in a beautiful home in the suburbs of Detroit with my parents and younger brother. I had every opportunity in the world, attended private schools, and even made it onto the honor roll. I was involved in dance, theater, and many of the school sports teams.
Beneath the surface, however, I always felt a lot of pressure to be perfect.
I was the first of 12 grandchildren, and this led to me feeling that I had to be the best at everything I did, which gave me terrible anxiety from the early age of 5.
The feeling had been stalking him for months. The lights were off in his bedroom, and the darkness closed in on him.
Isaiah Renfro, a top freshman wide receiver at the University of Washington, was at his home in South Los Angeles. He had to leave in the morning for spring practice, which was about to start in Seattle. But he could tell: Another storm was coming, a gale of anxiety and depression.
He slammed his suitcase shut and stood near his bed, steeling for a struggle that he was never sure he could win. He breathed hard, and tried to stay on his feet. Now the tempest was upon him. All the pressure. The worries. Football. Family. The feeling that he could never measure up.
As marijuana legalization builds momentum across the United States — with Michigan becoming the latest state to allow recreational use by adults — researchers are warning that more studies are needed on the long-term effects of chronic pot smoking on the human brain.
Marijuana is the most commonly used illicit drug in the United States, but little is known about its effect on health or how addictive it is.
According to a 2017 poll conducted by Marist College and Yahoo News, more than half of American adults have tried marijuana at least once in their lives, and nearly 55 million of them, or 22 percent, say they use it currently. Close to 35 million are what the survey calls “regular users,” people who say they use marijuana at least once or twice a month.
The use of medication to treat attention deficient hyperactivity disorder is linked to significantly lower risk for substance use problems in adolescents and adults with ADHD, according to a study led by researchers at Indiana University.
The risk of substance use problems during periods of medication use was 35 percent lower in men and 31 percent lower in women in the study. The results, based upon nearly 3 million people with ADHD in the United States, are reported in the American Journal of Psychiatry.
“This study contributes to growing evidence that ADHD medication is linked to lower risk for many types of harmful behavior, including substance abuse,” said Patrick D. Quinn, a postdoctoral researcher in the IU Bloomington College of Arts and Sciences’ Department of Psychological and Brain Sciences, who led the study. “The results also highlight the importance of careful diagnosis and compliance with treatment.”
Researchers at Washington State University have shown that offering prizes — from simple shampoo to DVD players — can be an effective, low-cost treatment for alcohol abuse, the nation’s third leading preventable cause of death.
The treatment was studied in Seattle-area participants with serious mental illness. Their lifespan is estimated to be 20-25 years shorter than the average person’s.
A surprise benefit of the treatment was that it decreased study participants’ tobacco and drug use.
Findings from the study, which appears in the current American Journal of Psychiatry, could expand treatment options for an estimated 15 million U.S. adults who abuse alcohol.
There are many reports of drug use leading to mental health problems, and we all know of someone having a few too many drinks to cope with a bad day. Many people who are diagnosed with a mental health disorder indulge in drugs, and vice versa. As severity of both increase, problems arise and they become more difficult to treat. But why substance involvement and psychiatric disorders often co-occur is not well understood.
In addition to environmental factors, such as stress and social relationships, a person’s genetic make-up can also contribute to their vulnerability to drug use and misuse as well as mental health problems. So could genetic risk for mental illness be linked to a person’s liability to use drugs?
This question has been addressed in a new study, published in the open-access journal Frontiers in Genetics.
A new study by the University of Toronto (U of T), found the lifetime prevalence of suicide attempts among adults who had been exposed to chronic parental domestic violence during childhood was 17.3% compared to 2.3% among those without this childhood adversity.
“We had expected that the association between chronic parental domestic violence and later suicide attempts would be explained by childhood sexual or physical abuse, or by mental illness and substance abuse. However, even when we took these factors into account, those exposed to chronic parental domestic violence still had more than twice the odds of having attempted suicide” reported lead author Professor Esme Fuller-Thomson, Sandra Rotman Endowed Chair at the University of Toronto’s Factor-Inwentash Faculty of Social Work and Institute for Life Course and Aging.
The study examined a nationally representative sample of 22,559 community-dwelling Canadians, using data from the 2012 Canadian Community Health Survey-Mental Health. Parental domestic violence was defined as “chronic” if it had occurred more than 10 times before the respondent was age 16.
A program developed at Boston Medical Center (BMC), which integrates addiction treatment into primary care for patients with or at risk for HIV, has been shown to lower patients’ substance dependence and encourage their engagement in treatment. The findings are published online in theJournal of Substance Abuse Treatment.
Injection drug use is the third most frequently reported risk factor for HIV infection in the United States, according to the Centers for Disease Control and Prevention (CDC). Similarly, those who ingest or inhale drugs such as alcohol, cocaine and methamphetamine, are at an increased risk for contracting HIV because their inhibitions are reduced, making them more likely to engage in risky sexual behavior.
“We know that this patient population often seeks care in emergency rooms where they see physicians who may not know their medical history,” said Alexander Walley, MD, attending physician in general internal medicine at BMC and the study’s lead author. “As a result, unhealthy drug and alcohol use often goes unaddressed. Our model aims to integrate evidence-based addiction treatment into primary care.”
Cocaine use causes ‘profound changes’ in the brain that lead to an increased risk of relapse due to stress — according to new research from the University of East Anglia.
New research published in The Journal of Neuroscience identifies a molecular mechanism in the reward centre of the brain that influences how recovering cocaine addicts might relapse after stressful events.
Importantly, the study identifies a potential mechanism for protecting against such relapses with treatment.
The research team looked at the effects of cocaine in rat brain cells (in vitro) and in live rats — particularly their ‘cocaine seeking’ response to stress.
