Medical Cannabis Access & Caregiving: A new U.S. analysis in Annals of Internal Medicine estimates 35,000+ clinicians can authorize medical cannabis and nearly 110,000 registered caregivers help patients obtain, grow, or manage products, with caregiver rates highest where home cultivation is allowed. Enrollment Trends: The same journal series reports medical cannabis registrations rose from ~747,000 (2016) to ~3.9 million (2024), but growth leveled as recreational access expanded, with mental health conditions driving more registrations. Safety Signals (Seizures): Multiple reports highlight research linking frequent cannabis use to higher seizure risk, including a study using a large U.S. hospital database that found near-daily users had about double the seizure likelihood versus non-users. Older Adults & CUD: Another Annals study finds 11.4% of older adult cannabis users meet criteria for cannabis use disorder, with risk rising alongside more frequent use. Policy & Regulation: California signed a law banning single-use, battery-powered vapes (nicotine/certain disposables), while Trinidad and Tobago proposes raising the legal age for cannabis consumption up to 25. Medical-Adjacent Tech: NIST says post-9/11 bomb-detection “headspace” methods are informing development of a marijuana breathalyzer for impaired driving. Legal/Enforcement: A Florida judge dismissed a THC patent suit against Trulieve, while a separate case in Virginia points to a long-running murder-for-hire matter involving a marijuana dealer.
