1/Must-read @nytimes.com opinion piece by #AcademyHealth's @aaronecarroll.bsky.social: #Cannabis policy moved faster than the evidence—& today’s commercial market has outpaced our #PublicHealth response. Question isn’t “legalize or not,” but whether we adjust to real harms. Read: bit.ly/3Ya3IdX

1/#Trump executive order on rescheduling #cannabis mistakenly treats all cannabis the same. For example: High-potency flower, 90%+ #THC vapes, concentrates & high-dose edibles carry very different risks & have no proven medical use - so they don’t belong on Schedule III. #PublicHealth #Marijuana

1/#Kaiser study we co-authored in #JAMAOpenNetwork shows how inconsistent & inaccurate info about #cannabis use in pregnancy remains across CA retailers, including: - 1 in 5 budtenders said it’s safe; - Only 40% said it’s unsafe; - <6% referenced the warning label Read: bit.ly/496EkvK

1/AP’s Laura Unger debunks a persistent myth: you can’t get addicted to #cannabis. #Stanford’s Dr Smita Das explains why #CannabisUseDisorder is real—& rising—as today’s products reach 20–40% #THC & higher. CDC Data: ~3 in 10 people who use #marijuana develop #CUD. Read: bit.ly/4ppIZ1b

1/New study from researchers at UC Irvine, UCLA & @publichealthinst.bsky.social’s Getting it Right from the Start shows more teens are using #cannabis more frequently & more intensely (reversing a prior decline) after retail stores opened in 2018 - raising serious health risks for California youth.

Our new Journal of Adolescent Health study (w. #UCLA & #UCIrvine)—featured by Fox 5 San Diego—found daily #cannabis use among CA 11th graders has risen since legalization, reversing prior declines. Youth use stays lower where retail sales banned. Stronger safeguards needed. Article: bit.ly/3W8Cvay

1/#SB378 (#ScottWiener) passed the #CALeg with overwhelming support. It cracks down on unregulated #hemp products flooding CA — often ultra-high #THC, synthetic, & sold online to youth with no age checks. We urge @gavinnewsom.bsky.social to sign this important bill!

1/CBS Sacramento’s Brady Halbleib interviews our own Dr. Lynn Silver on @gavinnewsom.bsky.social's signing #AB564 — a bill that breaks #Prop64’s promised funding for youth, prevention & the environment. A big tax break for #BigCannabis, nothing to fix the real drivers of the illicit market.

1/The #CALeg just passed #AB564, betraying voters’ intent in #Prop64. Instead of funding childcare, youth prevention, environmental restoration & public safety as promised, this bill hands #BigCannabis a massive tax break & raises serious questions of legality. #cannabis

1/#NatureCommunications study (via @cnn-news.bsky.social/#kcranews) finds #marijuana may damage human eggs (esp. higher #THC)—raising risks of infertility, miscarriage & genetic defects. #Cannabis use during pregnancy has tripled since 2002. Study adds to mounting evidence of risks when pregnant.

1/Lost Coast Outpost dives into #AB564, which would cut taxes for #BigCannabis & divert $100s of millions from kids, prevention, & environment—just as fed cuts do same.

1/In #CapitolWeekly, Michael Sutton — former CA Fish & Game president - reminds us of one of the MAJOR reasons why voters legalized #cannabis in CA: to generate revenue for #YouthPrevention, #Childcare, law enforcement & #EnvironmentalRestoration. #AB564 betrays that promise. #CALeg

1/We just co-authored a new study in Science Direct's #AddictiveBehaviors on #cannabis vape products (CVPs) among young adults. Findings show a strong link between exposure to CVP ads — especially on social media — & both likelihood & frequency of use. #CannabisPolicy #PublicHealth

1/NyTimes has a front page article on California’s ultra-potent #cannabis is being smuggled into the U.K. as “Cali weed.” It’s not only vastly stronger (up to 40% #THC) — it’s also “commonly sold in brightly colored packets with cartoonlike designs.” Read: www.nytimes.com/2025/09/01/w...

1/Friday’s CA Senate Approps vote in favor of #AB564 is a stark reminder of #BigCannabis’ oversized & corruptive influence. #CALeg bought the false narrative of an “industry in peril”—while the real cost is cuts to youth prevention, #publichealth, & environmental programs.

1/#LATimes #JennyGold takes deep dive: #AB564 & other #cannabis tax cuts would harm kids. Slashing excise tax strips ~$180M/yr from #Prop64 programs—#prevention, #childcare, youth & environment (on top of federal cuts), risking ~8,000 child-care slots. Read: www.latimes.com/california/s...

1/Child #cannabis poisonings in CA up 469% since legalization—driven by candy-like packaging & skyrocketing #THC levels. AS @publichealthinst.bsky.social's Dr. Lynn Silver said to #SacBee: “Cannabis is not strawberries…it has significant health harms & generates dependency.” Read: bit.ly/4mG82wk

1/New York Times's Megan Twohey exposes the alarming rise in pediatric #cannabis poisonings—from <1,000 in 09’ to 22,000+ last year. Many involve edibles mimicking candy, some sending toddlers to #ICU. Each stat is a terrified family & a preventable #PublicHealth crisis. Read: bit.ly/4mHGjuJ

1/CA State Auditor: The CA Department of Cannabis Control is failing (469% increase in ER visits for #cannabis poisonings) to keep #cannabis products (esp. that look & taste like candy) out of kids’ hands. We need a system that puts #PublicHealth & #YouthSafety above profit. KCRA: bit.ly/4oxo6BM

New York Times article reveals 85 people were sickened after #THC-infused oil was mistakenly used at a Wisconsin restaurant sharing a kitchen with a #cannabis #edibles business. CA just legalized (we opposed) this kind of co-location. We should be concerned. www.nytimes.com/2025/07/28/w...

New findings highlight risks of prenatal #cannabis use. Neonates exposed to cannabis in utero had significantly smaller total brain volume vs. unexposed peers, even after controlling for maternal stress. www.tandfonline.com/doi/full/10....

1/We urge the California Dept. of Public Health to finalize & make permanent the regs prohibiting intoxicating #hemp. These unregulated, high-#THC products—like Delta-8, Delta-10, THC-P—are being seized in schools, sold near campuses, & exposing kids to potent cannabinoids with no safety testing.
