Sponsor: Advice on restless leg syndrome from Parkinson’s: CBD, THC, CBN
Here’s an email from an old friend asking for advice & sharing their experience.
D’s partner has Parkinson’s disease. One of the problems is restless leg syndrome. He says, “Every doctor we have talked to has said there in no known remedy. Lately I have been giving her a dose of PlusCBD Extra Strength Formula Full Spectrum Hemp Extract with Monk Fruit, 250 mg, 10 mg per serving. It seems to help but I am just shooting in the dark with this and was wondering if you would recommend any other product that CV Science has for sleeping and restless leg? By the way, I continue to take tablets daily and, remarkably, my sciatic nerve problem has disappeared for the most part. For me it has been a miracle.”
I responded by saying that there’s two cannabinoids worth considering: THC & CBN.
For THC, these Reserve gummies provide 2.5 mg each. You can also get them with 5 mg of THC - or you can get them in capsule form if you don't like gummies.
2.5 mg of THC is enough she might get slightly high - so you can cut them in half while you're figuring out your dosage.
For CBN, there's these Reserve Sleep products that have CBD, THC, CBN & melatonin. So there's a lot going on in there. But for my wife, they were huge for helping her sleep more.
So start with just adding THC to see if that works - and then try with the full combo to see if that works better.

#Autism
In children with moderate to severe autism, CBD-rich extracts caused significant improvements
Clinical and Family Implications of Cannabidiol (CBD)-Dominant Full-Spectrum Phytocannabinoid Extract in Children and Adolescents with Moderate to Severe Non-Syndromic Autism Spectrum Disorder (ASD): An Observational Study on Neurobehavioral Management
https://www.mdpi.com/1424-8247/17/6/686
Brazil continues to be one of the leading places for research on the use of cannabinoids for children with autism. In this study of 30 children and adolescents from the ages of 5 to 18 with moderate to severe autism spectrum disorder (ASD), they were given full-spectrum extracts with a ratio of 33:1 CBD:THC for an average of six months. The doses started at 1 mg/kg (~18 mg for a 5-year-old) and on individualized plans reached an average of ~3 mg/kg. To determine results, the participants were given neuropsychiatric evaluations by their clinicians and their caregivers were interviewed. As the researchers concluded, “we found significant improvements in various symptomatic and non-symptomatic aspects of ASD, with minimal untoward effects”. The improvements observed included…
· increased communication skills
· improved attention and learning
· more eye contact
· diminished aggression and irritability
· an overall increase in both the patient’s and family’s quality of life
None of the caregivers reported worsening of symptoms and at least 80% of them reported improvements in quality-of-life measurements. The effects were particularly strong for lessening meltdowns, temper tantrums, and aggressiveness. In addition, almost 75% of the participants reduced or halted the use of one or more other medications.
On a personal note, one of the reasons I’m passionate about cannabinoids for autism is because of my young cousin who was on a trajectory to never leave parental care because of his ASD. But after trying many things to help, his mother somewhat reluctantly tried CBD-rich full-spectrum extracts. A few months of low doses (~10 to 20 mg per day) gradually changed everything for him. Years later, his life is much more independent than his mother would have imagined. And he hasn’t stopped taking the CBD since. (I have a guess that part of the benefits here come from the ability of cannabinoids to grow new brain cells and create new synaptic connections - but that’s just a guess. That research is currently too difficult to do in humans – and anyway, it’s the interviews with the caregivers that matter in the end). Everyone responds differently, but if you know someone with a moderate to severe level of autism, full-spectrum hemp extracts are worth exploring.

#Somatform
German public health data of cannabinoids for psychiatric disorders found a positive effect in the majority of cases
Cannabinoid Drugs in the Treatment of Psychiatric Disorders - Data from the German Federal Institute for Drugs and Medical Devices
https://pubmed.ncbi.nlm.nih.gov/38749455/
The Germans have had medical cannabis/cannabinoids since 2017. Any doctors who prescribed it was required to take part in a survey by the Federal Institute for Drugs and Medical Devices. Of those 16,000 case reports, over 5,000 involved the use of cannabinoids for psychiatric disorders. The majority of those were for somatoform disorders which include
· conversion disorder (neurological symptoms not explained by medical conditions)
· somatic symptom disorder (chronic physical symptoms that cause excessive thoughts and behaviors related to the symptoms)
· illness anxiety disorder (formerly known as hypochondria)
· body dysmorphic disorder
· pain disorder (chronic pain not explained by a medical condition).
The majority of treatments (80%) involved dronabinol, a synthetic pharmaceutical form of THC. But it should be noted that patients elsewhere tend to not like dronabinol. It can be a strong dose of psychoactivity with no moderating influence from anything else in the plant (a ‘horse kick’ someone once told me). Despite this, for this rather unusual array of mental health conditions seized on by German psychiatrists, overall the “doctors reported a positive effect on symptoms in at least 75% of the cases”.
More studies can be seen on the Mental Health page of CVResearch.info.
#NeuralEffects
In adults with one year of medical cannabis use, brain imaging showed no significant neural effects
Impact of year-long cannabis use for medical symptoms on brain activation during cognitive processes
https://pubmed.ncbi.nlm.nih.gov/38746368/
One worry with long-term medical cannabis use is neurocognitive effects. In this observational cohort study over three years, medical cannabis patients agreed to fMRI brain scans during tests in the domains of working memory, reward, and inhibitory control. They were tested before they began medical cannabis and compared to a control group. After a year of use, the functional imaging showed “no statistically significant difference in brain activation” between those with medical cannabis cards and those without.

An analysis of hemp farmers in Kentucky & what makes the crop economically attractive
What Makes Hemp Economically Attractive? A Case of Kentucky Hemp Farmers
https://ideas.repec.org/a/ags/reowae/343136.html
“The regression analysis results show that Kentucky hemp acreage positively responds to an increase in cannabidiol (CBD) biomass price. When CBD prices increase by 10%, hemp acreage would increase by approximately 1%.”
Therefore, with CBD prices crashing these last years, the acreage of hemp planted in the US has plummeted as well. Despite rather cynical political promises, hemp was never going to save the farmers, especially when all it would take is three big farms in the Midwest to supply the entire nation's CBD needs.

#21 - Destroy the seed of evil, or it will grow up to your ruin
“The proverb is used at the end of the fable The Swallow and the Other Birds. It tells the story of a swallow bird and other birds. They were picking seeds sown by the countrymen. The swallow bird cautioned other birds to pick up the hemp seeds; otherwise, they would repent. The other birds did not listen to the swallow, and the hemp seed grew, and the countrymen made cords and nets from the hemp. The countrymen used the same trap to catch the birds.”

PS: For today’s crusading pianist, Hazel Scott’s ‘Relaxed Piano Moods’. Born in Trinidad but raised in NYC, Scott was a musical prodigy who started studying classical music at Juilliard at the age of 8. Experimenting with mixing jazz & classical into “swinging the classics”, she became a beloved nightclub act by the late ‘30s & had her own radio show. Along with Lena Horne, she was one of the first Black women to get big roles in Hollywood, which she began by turning down 4 roles of “singing maid” stereotypes. In 1950, she became the first Black person to have their own television show. It became so popular that episodes soon ran three times a week. To get a sense of her stature, supporting musicians on the show included Charles Mingus & Max Roach. But she lost that show after appearing before & protesting against McCarthy’s Red Scare tribunal, the House Un-American Activities Committee (HUAC). And on the road, she continued her commitment to civil rights, refusing to appear in segregated venues & successfully suing a restaurant that refused to serve her & a companion. Her public opposition to McCarthyism & racial segregation led her to relocate to France for ten years before returning to support the US Civil Rights Movement. She used her power to open the door wider for performers who came after her & led a life committed to her art & to creating a more just world.
