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.

Absolutely iconic poster from #cannabis legalization movement, from about 40 years ago -- great quote from Spinoza. At the bottom, inscribed, "to Lester Grinspoon"

Look what I just inherited (3 years after my dad died; have to fix frame). Original @NORML poster.
Spinoza: "he who seeks to regulate everything by law is more likely to arouse vices than to reform them."
(I grew up with this poster.)

So inspiring to be out with tens of thousands of others protesting against our idiot president & the way that he's looting our government, destroying our democracy, our climate, our justice system, our education, our social safety net --he's a disaster from start to finish.

Still getting over my jet lag from wonderful visit to Australia -- really enjoyed speaking at United in Compassion medical #cannabis conference, seeing (and meeting) the band @Grinspoon (they are spectacular!!) and getting to hold a friendly Koala.

Absolutely wonderful getting to meet & see the band @Grinspoon (while we were in Australia speaking at a medical #cannabis conference). Named after my dad, they are a fantastic band, spectacular live in concert, & the nicest people you'll find. Great to meet you @philjamieson!!

If anything is left intact after this Administration, I will be amazed; firing CDC workers (and pulling out from the WHO) with Bird Flu epidemic is about to hit is suicidal.
(Not to mention we are destroying the climate with abandon...just to make a very few people rich)

My #addiction textbook contains things that aren't true, especially #cannabis but also:
'repeated ketamine use produces cognitive deficits & depressed mood in the majority of active #ketamine users; the degree of reversibility remains unclear."

Studying for my #addiction boards and I continue to be astounded by how off-base the field of addiction medicine is about #cannabis. They are hysterical about it. This is an ASAM @ASAMorg textbook. They make it seem as dangerous than PCP! The entire textbook is like this.
