Cannabis smoke and oral Δ9THC enhance working memory in aged but not young adult subjects.

With increased legalization of recreational and medical cannabis, use of this drug is growing rapidly among older adults. As cannabis use can impair cognition in young adults, it is critically important to understand how consumption interacts with the cognitive profile of aged individuals, who are already at increased risk of decline. The current study was designed to determine how cannabis influences multiple forms of cognition in young adult and aged rats of both sexes when delivered via two translationally-relevant routes of administration.

The Associations of Kratom (Mitragynine), Opioids, Other Substances, and Sociodemographic Variables to Drug Intoxication-related Mortality.

Introduction: The US age-adjusted drug overdose rate increased by 298%, with fentanyl being the main contributor to drug overdose deaths. The contribution of kratom to drug overdoses or intoxication is seldom reported despite its increasing use and detection among overdose decedents.

Methods: Our cross-sectional study utilized deidentified data from the Florida Department of Law Enforcement, 2020-2021 (N = 30,845).

Kratom (Mitragyna speciosa) use for self-management of pain: Insights from cross-sectional and ecological momentary assessment data.

Kratom (Mitragyna speciosa) is increasingly used in the US for self-management of pain, despite limited research on its efficacy and safety. To better understand how and why people use kratom for pain self-management, we analyzed baseline survey data (N = 395) and 15-day ecological momentary assessment (EMA) data (N = 357) from kratom consumers across the US. Although we recruited participants based on their kratom use, not on whether they used it for pain management, nearly half (49.
