Sponsor: PlusCBD & a commitment to education & research
One sign of a great CBD company is when they go to the next level for educating their customers. PlusCBD has articles for all levels of knowledge, videos about how CBD works & a YouTube channel of great educational content.
(Plus, they even sponsored two seasons of my podcast ‘The Lex Files’)
In addition, they’ve done more peer-reviewed research than any other company other there. They put their money down to advance the field.
Check out this (partial) bibliography:
A GRAS (Generally Recognized as Safe) study on hemp extracts to prove their safety
A clinical trial on healthy people to show that hemp extracts helped their cholesterol, sleep quality, stress response & perceived life pleasure
A post-marketing safety study where experts went over 2 years of PlusCBD’s adverse event reports to find the high safety levels
A case series of using CBD to treat PTSD
And funding me to create the extensive cannabinoid science archive at CVResearch.info
PlusCBD takes their commitment to education & research to the next level. And they do the same with their products.

The first randomized control trial on CBD for dental pain found significant & quick pain reduction
Cannabidiol as an Alternative Analgesic for Acute Dental Pain
https://pubmed.ncbi.nlm.nih.gov/37910667/
The doses were 10 mg/kg (700 mg for a 70 kg/150 lb adult) up to 20 mg/kg (1400 mg).
“Compared to placebo, sedation, diarrhea, and abdominal pain were significantly associated with the CBD groups (P < 0.05). There were no other significant psychoactive or mood change effects.”

An evergreen note on reading restricted papers:
First stop for seeing if there’s a free version of a paper, use the Google Scholar Chrome extension (Mac version), Google Scholar itself or try ResearchGate.
Three other helpful browser extensions are: Unpaywall, Open Access Button & PaperPanda
For the infamous backdoor, use Sci-Hub – the pirated papers repository (Chrome extension here). This works better for older paper than the stuff that just came out.
Finally, email the author. They’re almost always happy to oblige because, thanks to the predatory academic publishing system, they don’t make a dollar off of their papers.
