Happy Thanksgiving everyone! I bet no one else has a 95 year old mom who smokes three joints at once and simultaneously visits Saturn....

'existing evidence does not demonstrate greater long-term cognitive or neurophysiological harm attributable to #cannabis use in individuals aged 18–25 years compared to those older than 25' (it is the early/mid teens we need to focus prevention on) www.tandfonline.com/eprint/KKVE8...

What these studies don't factor in is that people often use #cannabis INSTEAD of more dangerous pharmaceuticals (opioids, benzos, Ambien, etc), and that the health-related quality of life goes up with medical #marijuana (though agree we need more research) www.liebertpub.com/doi/full/10....

1) Easy to not find evidence of benefit if you don't look 2) Few (if any) of these authors have ever treated single patient with medical #cannabis 3) One-sided, biased papers are why patients don't discuss #marijuana use with their doctors -- a huge loss! jamanetwork.com/journals/jam...

'CBMP [cannabis based medicinal product] treatment over 24 months was associated with improvements in health-related quality of life and was well-tolerated in patients with MS.' #cannabis karger.com/mca/article/...

My latest blog, controversial issue: "Congress has just recriminalized Hemp-derived Products: Was this a good idea?' I present arguments on both sides of the issue (and, as such, will therefore annoy all parties involved...) #cannabis #Hemp #THC drpetergrinspoon.substack.com/p/congress-h...

Interesting article on #cannabis and #Alzheimers journals.sagepub.com/doi/10.1177/...

Primary care at Mass. General Brigham is in free-fall; I know dozens of doctors who want to leave; if MGB would ONLY recognize our union (which 88% of PCPs voted for) AND stop stealing our wages (& giving us untenable amounts of work), it would be better. www.bostonglobe.com/2025/11/24/b...

Glad to be included in great article @statnews about contentious issue of recriminalizing hemp-derived products; just as in recent blog, I show the arguments for both sides. www.statnews.com/2025/11/24/h...

Please check out latest blog about how field of #addiction medicine does not understand context in which most people use #cannabis (i.e., "all use is abuse"); they are miseducating doctors about medical #marijuana by hyperfocusing on harms over benefits drpetergrinspoon.substack.com/p/reefer-mis...

All things being equal...the turkey DOES taste better on #cannabis (and some relatives might be easier to deal with...) www.wsj.com/lifestyle/th...

"#Cannabis reduced the urge for alcohol in the moment, lowered how much alcohol people consumed over a two-hour period and even delayed when they started drinking once the alcohol was available." (I see this, clinically & have substack blog about it.") psychiatryonline.org/doi/10.1176/...

Interesting! 'We initially demonstrate that low-dose THC-CBD potentially can be an effective and safe therapeutic option for AD-related dementia.' #CannabisCommunity pubmed.ncbi.nlm.nih.gov/41160460/

A lot of people found this blog helpful, about the Endocannabinoid System, which explains how #cannabis works, how it helps regulate all of our other bodily systems, anad why people withdraw from #marijuana after heavy use. drpetergrinspoon.substack.com/p/the-miracu...

Check out my video on #cannabis for older adults; this is what my next book (on 5/5/26) is about! www.youtube.com/watch?v=jGJy...

I visited a concierge medical practice. It's not a mystery why the rich are living longer than the poor, while hospitals are cashng in. Check out my YouTube video on this topic to go with my blog. Substack/blog: drpetergrinspoon.substack.com/p/a-tale-of-... YouTube: www.youtube.com/watch?v=-7tA...

I visited a concierge practice and was blown away by the difference in the level of healthcare provided (from my inner-city clinic) -- all within the same hospital system. The rich are living longer & the hospitals are cashing in. Check out my blog: drpetergrinspoon.substack.com/p/a-tale-of-...

I'm quoted in Oprah Daily about how #cannabis can impact sexuality (usually for the better...). www.oprahdaily.com/life/relatio...

As a primary care physician at MGH, I’m seeing more and more older adults turn to #cannabis and #CBD — not just for curiosity, but because these treatments are helping with sleep issues, anxiety, and chronic pain Please check out my video on this topic www.youtube.com/watch?v=jGJy...

'This study’s findings indicate cannabis may be a substitute for opioids in the management of cancer-related pain.' (Many of us have been using #cannabis to help #cancer pain for decades...glad medical community is catching up...) jamanetwork.com/journals/jam...

t's good that @JAMA_current is finally advocating for teaching doctors about medical #cannabis (and, only 54 years after my dad, Dr. Lester Grinspoon, was urging this for all doctors in his book 'Marihuana Reconsidered."). jamanetwork.com/journals/jam...

Interesting study about #cannabis and #chronicpain. 'Cannabis Product Beats Placebo for Common Chronic Pain — Phase III trial shows efficacy." www.medpagetoday.com/rheumatology...

Another hige blow to our ability to provide high quality primary care at my hospital (if you even can find a PCP). We can't get patients in to specialists in a safe/timely manner; now they are making it virtually impossible to ask them for clinical advice. www.bostonglobe.com/2025/09/23/b...

Why can no one find a PCP? Instead of minimally supporting current primary care docs, many of whom are close to giving up completely, my hospital system, MGB, is planning providing primary care by nurses (without any doctors...) at CVS Minute Clinics. commonwealthbeacon.org/opinion/foll...

Check out my new video on the urgent need to decriminalize opioids, following on the success of #cannabis legalization. People are mostly overdosing/dying from ILLEGAL opioids. Time to wind down the War on Drugs (which we are losing). drpetergrinspoon.substack.com/p/an-argumen...

Delta-8-tetrahydrocannabinol use more common where marijuana remains prohibited and less common where delta-8-tetrahydrocannabinol sales are regulated or prohibited (legalize #cannabis & you get rid of these dangerous and unrelated hemp-derrived products) www.ajpmonline.org/article/S074...

This is awful. Harm reduction saves lives and prevents disease, and we are moving away from it. People with #addiction are the ones who are going to suffer (as usual...). www.nytimes.com/2025/08/25/h...

Glad to be included in this @Medscape article about what awful patients doctors are in their own personal lives. (though we don't hate patients....histrionic headline...) www.medscape.com/viewarticle/...

Thanks to the @SmithsonianMag for including me in this thoughtful piece about #cannabis and #psychosis. www.smithsonianmag.com/science-natu...

I'm on @FoxNews explaining why #cannabis rescheduling is a win for all of us on all levels -- it will help us understand potential harms, benefits, & how to treat patients more effectively (which means fewer opioids and NSAIDs both of which can be lethal) www.fox32chicago.com/news/trump-c...

Important: we have to stop preferentially screening black women for #cannabis use during pregnancy (with drug tests), and we have to stop separating them from their newborns if positive -- this is medicine gone amok and causing more harm than good. jamanetwork.com/journals/jam...
