✈️ TSA Quietly Updates Marijuana Policy, But Federal Rules Still Apply
According to SFGate, the TSA quietly updated its guidance to clarify that medical marijuana may be allowed in both carry-on and checked baggage, while emphasizing that agents are focused on security threats, not searching for drugs. However, the change does not legalize cannabis for air travel, and if marijuana is discovered, TSA can refer passengers to local or federal law enforcement, with outcomes depending on the laws at the departure or destination airport. The update mostly reinforces longstanding policy rather than creating a major shift, leaving travelers in a legal gray area where state legalization conflicts with federal prohibition, especially when flying between states with different cannabis laws.

🌿 Federal Study Links Marijuana Legalization to Significant Drop in Opioid Overdoses
A federally funded study found that states with legal medical or recreational marijuana experience significant reductions in opioid overdoses, particularly among working-age adults with employer-sponsored health insurance. Analyzing data from over 107 million people between 2011 and 2021, researchers observed that access to medical cannabis dispensaries was associated with about a 15.5% decrease in non-fatal opioid overdoses, while recreational legalization was linked to nearly a 12% reduction. The findings suggest a potential “substitution effect,” where some individuals may use cannabis instead of opioids for pain management, helping lower overdose risk. While researchers stress that cannabis is not a standalone solution to the opioid crisis, the study adds to growing evidence that expanding cannabis access could serve as a complementary harm-reduction strategy alongside traditional addiction treatment and public health efforts.

📈 When Countries Collapse, Cannabis Markets Become Survival Economies
Scientists discovered that removing a key enzyme (DAGLα) in the cerebellum disrupted the brain’s endocannabinoid system in mice, making them more anxious and less social. The enzyme normally produces 2-AG, a chemical messenger that helps neurons fine-tune their communication. Without it, the mice’s brain cells were less adaptable, affecting both movement and emotions. Researchers say the findings could lead to targeted therapies to boost endocannabinoid signaling and improve quality of life for people with autism, anxiety, and other social or emotional challenges.

🫁 Heavy Cannabis Use Linked to Higher Lung Cancer Risk, but Safe Limits Remain Unclear
A large-scale analysis of more than 118 million U.S. medical records suggests that heavy cannabis use, particularly cases classified as cannabis use disorder, is associated with a significantly higher risk of lung cancer, with affected individuals showing more than three times the likelihood of diagnosis compared to non-users. The elevated risk persisted even after accounting for tobacco use and was observed across multiple cancer types, strengthening concerns about long-term respiratory effects. However, researchers emphasize that the broader relationship between cannabis and cancer remains complex, with ongoing debate around dosage, frequency and consumption methods, and limited evidence on whether occasional or non-smoked use carries similar risks.
