Marijuana use amongst youth stable, but substance abuse admissions up

While marijuana use amongst youth remains stable, youth admission to substance abuse treatment facilities has increased, according to new research from Binghamton University, State University of New York.

Miesha Marzell, assistant professor of social work at Binghamton University, along with researchers at The University of Iowa, did a secondary analysis of data collected from every nationally funded substance abuse treatment facility in the United States from 2003-2013. The data covered admissions before and after major marijuana policies were enacted nationwide. The team’s analysis showed that while marijuana use amongst youth has remained relatively unchanged, admissions to substance abuse treatment facilities has increased.

“Teens were being admitted to substance abuse treatment centers across the United States, but they were not necessarily indicating that their marijuana use was at a high-risk,” said Marzell.

First secondhand smoke, now secondhand harm from drinking

It’s no secret that university life often includes alcohol use, which can sometimes cause harm. Yet harm can also extend beyond the drinker, such as “secondhand harm” that is caused by intoxicated people: accidents or domestic, physical, or sexual violence; interrupted sleep or property destruction; and arguments, problems with relationships, or financial problems. Prior research suggests that more than 70 percent of college undergraduates have experienced harm from other students’ drinking. This study examined the prevalence and types of secondhand harm among Canadian undergraduates, and whether certain personality risks for alcohol use disorder — impulsivity, sensation seeking, hopelessness, anxiety sensitivity — can predict secondhand-harm exposure.

Researchers administered an online survey to 1,537 first-year Canadian undergraduates (two-thirds of whom were women) during 2015. Problematic alcohol use was measured by the Alcohol Use Disorders Identification Test (AUDIT) and personality was measured by the Substance Use Risk Profile Scale (SURPS). The 11 secondhand-harm choices given to students ranged from “interrupted your studies” to “sexually harassed/insulted you.”

Survey Finds Many Doctors Underprescribing Buprenorphine

Doctors are underprescribing the opioid addiction medicine buprenorphine, according to a new survey of addiction specialists.

Buprenorphine can be used to treat opioid addiction in the privacy of a doctor’s office. Doctors who prescribe the medication must have a waiver allowing them to do so. Until recently, doctors with waivers could prescribe buprenorphine to 100 patients. This year, the cap was raised to 275, HealthDay reports. More than half of the doctors with a waiver said they were not currently prescribing the buprenorphine to capacity, according to the survey, which was presented at the American Psychological Association annual meeting.

Compound derived from marijuana interacts with antiepileptic drugs

New research published in Epilepsia, a journal of the International League Against Epilepsy (ILAE), suggests that an investigational neurological treatment derived from cannabis may alter the blood levels of commonly used antiepileptic drugs. It is important for clinicians to consider such drug interactions during treatment of complex conditions.

Cannabidiol (CBD), a compound developed from the cannabis plant, is being studied as a potential anticonvulsant, and it has demonstrated effectiveness in animal models of epilepsy and in humans. An ongoing open label study (Expanded Access Program) conducted by investigators at the University of Alabama at Birmingham is testing the potential of CBD as a therapy for children and adults with difficult to control epilepsy. The study includes 39 adults and 42 children, all of whom receive CBD.

Because all of the participants are also taking other seizure drugs while they are receiving the investigational therapy, investigators checked the blood levels of their other seizure drugs to see if they changed. “With any new potential seizure medication, it is important to know if drug interactions exist and if there are labs that should be monitored while taking a specific medication,” said lead author Tyler Gaston, MD.

Parents have critical role in preventing teen drinking

Fewer Australian teenagers are drinking alcohol but more needs to be done to curb the drinking habits of Aussie students, based on the findings of the latest study by Adelaide researchers.

More than 2800 Australian students aged 12-17 took part in a survey of drinking behaviour, conducted by researchers from the University of Adelaide’s School of Psychology and the Population Health group at the South Australian Health and Medical Research Institute (SAHMRI).

The results of the study, now published in the journal BMC Public Health, provide a snapshot of the prevalence of alcohol consumption among students, and the factors that most influence their drinking behaviour. This research has been supported by Cancer Council SA and SA Government.
