I'm outta here. But I'm still working hard. Contact info in bio.

Every year, more states legalize #cannabis or permit medical use. Yet the federal government still views it as an illegal drug. Absent federal oversight, states have enacted a patchwork of policies for testing, quality, & safety, roles usually fulfilled by @EPA, @US_FDA, & @USDA.

My latest on regulation and risks of #cannabis contaminants: "A lack of rigorous, universal standards for regulating common contaminants has significant implications for public health, write the authors of a new study in @EHPonline." #environmentalhealth

The World Anti-Doping Agency can't seem to shake reefer madness. 💨 Last month, they ruled that THC will remain banned during competition and at levels in urine tests that indicate frequent use outside competition. Read more:

Hey, it's my latest column for @projectcbd. This one covers recent research into the #neuroprotective properties of #cannabis -- including not only cannabinoids but also terpenes, flavonoids, and other compounds.

Marijuana can cause bronchitis, but a moderate body of literature suggests distal airway/parenchymal lung disease doesn't occur; [it] doesn't cause chronic obstructive pulmonary disease & likely doesn't cause lung cancer, distinctly different from tobacco.

One more new paper: https://t.co/yWOxw4826j "In this older high-risk cohort, smoking cannabis was associated with higher social and behavioral risk, but with fewer chronic health conditions."

"Psychedelics & their associated practices are given unconventional mystical meanings by some high-profile tech entrepreneurs, & these meanings are integrated into belief systems & philosophies which are anti-democratic, individualist, & essentialist."

More evidence for the benefits of 1:1 THC:CBD cannabis. You can still get high and will have better recreational and therapeutic outcomes. I promise.

"LSD produced long-lasting and notable reductions in anxiety and comorbid depression symptoms up to 16 weeks." https://t.co/md3IVsH2OV

A big hell yes to this column. (Other than the amanita muscaria image.) If you're interested in psychedelics, give it a read and some thought. https://t.co/XqjKmUpjSG

Secret files suggest chemical giant feared weedkiller’s link to Parkinson’s disease

"Harmful chemicals emitted from wells increase levels of air pollution in nearby communities. Exposure to air pollution has also been linked to low birth weight. Water contamination caused by spills on & near well pads could also be a contributing factor."

Is THC performance-enhancing? The science says no. What's more, current @wada_ama policy can produce false positives (meaning no intoxication, but still over the limit) if previous #cannabis use is too frequent or doesn't stop soon enough. Read more in my latest for @ProjectCBD.

Thanks for the story @Mary_Biles, inspired me to make a healthful+delicious cup of hot chocolate this afternoon using organic cacao powder, pinch of organic sugar, & splash of organic milk. Lifelong chocolate lover but #TIL that #cacao contains #anandamide & two analogues.

“The trouble is, LSD attracts unstable therapists as much as it does the neurotic patient. It gives them an intoxicating sense of power to bestow such a fabulous experience on others.” Sidney Cohen 1963. Rarely discussed, but possibly #psychedelic medicine’s greatest threat.

Sunday night reading for Bay Area water geeks: my latest for @SFEstuary https://t.co/r4Z6WQBpZJ

"For athletes in @wada_ama -aligned sports organizations around the world, #cannabis use off the field could still derail a career, just like it did for Sha’Carri Richardson, the track star banned from US Olympic competition because she tested positive for weed."

Athletes can always partake of their “inner cannabis,” but when it comes to herb, weed, or extracts from the cannabis plant, Olympians and participants in hundreds of other sports organizations around the world still have to be careful.
