Check out my latest blog. How do you know when your drug use is addictive or if it is reasonable? How does it affect your family? What are the guardrails? How do you distinguish "safe" drug use from #addiction?

High Schools Are Losing the Struggle to Block PotβEven During Class
Legalization makes marijuana culturally acceptable and easy to get; βit was a party in the bathroom.β
Agree that teens need to avoid #cannabis use ("Just Say Wait"), but sensationalist @WSJ article ignores fact that teen usage of #marijuana is NOT rising with legalization (and weed has, unfortunately, always been easy to get for teenagers...)

Cannabis, Aging and Cognition: An Urgent Need for Research - Deepak Cyril DβSouza, Prakash Gupta, Ashley M. Schnakenberg Martin, Michael C. Stevens, Godfrey D. Pearlson, 2026
This article on need to study effects of #cannabis on older adults (I agree..) neglects that patients are using medical #marijuana INSTEAD of more dangerous pharmaceuticals like NSAIDS, opioids, benzos and hypnotics (e.g., Ambien) which is harm reduction.

Big Cannabis just funneled millions to Trump
Undermining the social justice movement that legalized cannabis
New blog:
In what universe does it make sense for Big Cannabis to bankroll Trump? When corporate cannabis aligns with anti-democratic power, it betrays the patients and activists who fought for legalization. We need legalization without corruption.

Man shot and killed by federal officers in Minnesota was an ICU nurse, his parents say
The man who was shot and killed by a federal officer during an immigration operation has been identified as 37-year-old Alex Pretti, an intensive care unit nurse.
Off topic for me -- but we all need to push back against ICE, Trump's version of the Gestapo, which is harming (and now murdering) innocent civilians/peaceful protesters; most of the immigrants peaceful too - Trump is destroying fabic of our democracy.

High January Is the New Dry January
As long as people are careful not to consume too much THC, and don't plan on driving, #cannabis drinks are significantly safer than alcohol (which was associated with 178,000 deaths last year); this is harm reduction.

A Brother's Battle with Leukemia and What Cannabis Did

Before I was a doctor, I was a kid watching my older brother Danny endure chemo for leukemia. Cannabis was the only thing that stopped the nausea & vomiting before he died at 16. It was the '70s, and using it meant breaking the law. Watch the full video at youtu.be/-MWHVhlIHwk

Inside Minnesota Hospitals, ICE Agents Unnerve Staff
This is so far beyond acceptable, and needs to stop;
ICE is a fascist army that needs to be dismantled.
'agents have broken hospital protocol, refused to provide documentation and, in some cases, gotten into shouting matches with doctors and nurses.'
