: In observational and retrospective studies, people who use cannabis are more likely than people who do not use cannabis to also use other drugs. People who take medical cannabis are also more likely to report medical and non-medical use of opioid analgesics, stimulants, and tranquilizers. ⋯ Studies comparing people who take medical cannabis with people who do not take it cannot draw conclusions about the effect of medical cannabis on drug use. To fully understand the effect of medical cannabis on the use of other drugs, prospective longitudinal studies randomizing individuals to cannabis versus other treatments are urgently needed.

Unintentional opioid overdose deaths are a public health crisis, and naloxone is the most effective harm reduction tool to curb many of these deaths. There is growing evidence that take-home naloxone can prevent opioid overdose in targeted populations. The goal of this study is to measure the opioid overdose reversal rate with take-home naloxone among participants with a diagnosis of opioid use disorder (OUD) in an opioid treatment program (OTP) setting. ⋯ This study validates that naloxone is not commonly used on the index study participant, but is often used on a secondary target among people who inject drugs. The large number of overdose reversals reported in this prospective study suggests that this novel model for naloxone use may be replicated at other OTP settings to reduce opioid overdose deaths.

Observational Study
Electronic Cigarette Use Among Counseled Tobacco Users Hospitalized in 2015.
Few studies have examined the prevalence of electronic cigarette use among the inpatient population regardless of the patients' cessation goals. The objectives of this study were to examine the prevalence of electronic cigarette use among counseled tobacco users admitted to 2 academic hospitals. ⋯ Screening hospitalized cigarette smokers for electronic cigarette use offers an opportunity to counsel all patients on evidence-based quit aids. Young, female patients are most likely to use electronic cigarettes and may benefit most from directed discussions about electronic cigarette use and Federal Drug Administration-approved cessation methods during smoking cessation counseling.

Recently, more than 63% of the 52,404 drug overdose deaths in the United States involved heroin and opioid pain medications. More than 30% of opioid-related deaths also involved benzodiazepines. Previous studies examining the extent of concurrent opioid and benzodiazepine use have relied on prescription data. To gain fuller insight into the extent of the concurrent use problem, we analyzed opioid and benzodiazepine prescription patterns in the context of drug testing results. ⋯ The extent of concurrent use of benzodiazepines and opioids, particularly non-prescribed use, suggests the need for more effective clinician assessment and intervention. The results support the Centers for Disease Control and Prevention opioid prescribing guidelines that drug testing occur before and periodically throughout opioid use and suggest that this testing should be extended to patients prescribed benzodiazepines as well.

Randomized Controlled Trial
Ondansetron Does Not Reduce Withdrawal in Patients With Physical Dependence on Chronic Opioid Therapy.
Individuals taking opioids for an extended period of time may become physically dependent, and will therefore experience opioid withdrawal should they stop taking the medication. Previous work in animal and human models has shown that the serotonin (5-HT3) receptor may be implicated in opioid withdrawal. In this study, we investigated if ondansetron, a 5-HT3-receptor antagonist, could reduce the symptoms of opioid withdrawal after chronic opioid exposure in humans. ⋯ We hypothesized that ondansetron would reduce opioid withdrawal symptoms in human subjects, but found no difference in withdrawal severity between ondansetron and placebo sessions. These findings suggest that more investigation may be necessary to determine if 5-HT3-receptor antagonists are suitable treatment options for opioid withdrawal.
