Providers with labor requirements are less likely to offer recommended treatment and more likely to operate without a state license.
A new study found that varenicline, a medication used to quit smoking, can help men with cannabis use disorder reduce their cannabis use. However, the same treatment showed no significant effect on female participants. Women who received varenicline reported higher withdrawal and craving scores and lower medication adherence compared t...

People who rated the suitability of using cannabis in these situations more highly were also more likely to consider using the drug.
Dr. Volkow emphasizes the importance of prevention strategies and research on stress, trauma, and social determinants in substance use disorders. She also highlights promising new directions in treatment, including GLP1 medications, to address the treatment gap in addiction.
A new study by Oregon Health & Science University researchers found that Medicaid waivers for addiction treatment have not led to increased treatment or reduced nonfatal overdoses in 17 states. The authors suggest that while the waivers may be necessary, they are insufficient to address the national opioid epidemic.
Researchers at Virginia Tech's Fralin Biomedical Research Institute found that restricting menthol cigarettes led to an increase in the purchase of nicotine replacement options. This shift is likely due to the fact that menthol flavors are perceived as more appealing, making alternative products a practical substitute.
A new study published in the Journal of Substance Use and Addiction Treatment found that distributing free naloxone via vending machines in county jails can sharply increase the number of doses provided to inmates at release. This may help reduce overdose deaths, as former prisoners are more vulnerable due to lack of accessible support.
Researchers developed an implantable device that detects an overdose, rapidly delivers naloxone to prevent death and alerts emergency responders. The device was tested in animal studies, showing promising results with rapid rescue and full recovery within minutes.
A large federally funded study found a 37% reduction in overdose deaths from opioids combined with stimulant drugs other than cocaine, primarily fentanyl and methamphetamine. Intervention communities implemented evidence-based practices, including naloxone distribution and education campaigns, which led to lower death rates.
Researchers found a significant increase in the use of naloxone by people without medical training to treat opioid overdoses. From June 2020 to June 2022, EMS reported 24,990 patients receiving naloxone from an untrained bystander before EMS arrived, representing a 43.5% growth.
