The use of cannabis may have a negative impact on outcomes for a common bypass surgery, a study suggests. Patients who used cannabis prior to lower extremity bypass had decreased patency, meaning the graft had a higher chance of becoming blocked or occluded, higher rate of amputation and opioid use after discharge.

A first-of-its-kind study published today in AACC’s Clinical Chemistry journal shows that a novel drug test detects a new class of synthetic cannabinoids called OXIZIDs. This test could enable drug enforcement agencies to identify OXIZID users and could play a critical role in efforts to stop the spread of these drugs.

Teen use of alcohol and alcohol in combination with cannabis is decreasing, but use by girls is decreasing more slowly than it is for boys, according to a study published in Alcoholism: Clinical & Experimental Research. And, rates of cannabis use among teens who didn’t use alcohol, which more than doubled in the last decade, are increasing more rapidly in female students than in their male counterparts. Despite the declines in alcohol use, teen alcohol use remains high, and far more prevalent than cannabis use. The simultaneous use of cannabis and alcohol amplifies the health risks for teens, including risk of intoxication, injury, impairment and other short- and long-term consequences for adolescents. As one in five students reports simultaneously using both substances, continued public health efforts to reduce teen alcohol and cannabis use, as well as interventions specifically aimed at female students, are important.

As the cannabis derivative delta-8-THC grows in popularity, it’s important for drug tests to be able to detect and differentiate it from delta-9-THC—the primary psychoactive ingredient in cannabis. Breaking research showcased at the 2022 AACC Annual Scientific Meeting & Clinical Lab Expo demonstrates that common drug testing methods can do just that.

They may only be in 4th or 5th grade, but 1 in 10 pre-teen children already say they’re curious about using alcohol or tobacco products, and 1 in 50 say they’re curious about using marijuana, a new study shows. As many as 3% of the nearly 12,000 9- and 10-year-olds surveyed say they already have a friend who uses one of these substances. And those who said they did were also much more likely to be curious about trying alcohol or tobacco and other nicotine-containing products themselves.

A five-year study has highlighted the importance of healthy sleep patterns in relation to future binge-drinking and cannabis use in adolescence and young adulthood, as reported in Alcoholism: Clinical and Experimental Research. The work builds on growing evidence that sleep characteristics are predictive of future substance use and related problems in young people, and could inform strategies for substance use prevention and intervention. Most previous studies assessed only a small range of sleep characteristics, and had limited follow-up. In the new analysis, researchers used six annual assessments from the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) study to examine whether multiple sleep characteristics in any year predict alcohol and cannabis use the following year. Data from over eight hundred NCANDA study participants, aged 12 to 21 at baseline, were included.
