Dramatic response to Laetrile and cannabidiol (CBD) oil in a patient with metastatic low grade serous ovarian carcinoma
A recent case study has examined a patient’s response to the consumption of cannabidiol (CBD) as a treatment for a rare type of ovarian cancer. Rather than participate in chemotherapy, which has been shown to only be effective in 5% of patients with low grade serous ovarian carcinoma, an 81-year-old decided to take a combination of amygdalin and CBD. Although CBD has only been shown to have effective anti-cancer properties in murine models the featured patient reported a significant decrease in tumor size, revealing that CBD may, in fact, be an effective treatment for patients looking into alternative care methods.
Although proven ineffective, the use of amygdalin highlights alternative therapies derived from naturally occurring chemicals found in common plants. Flavonoids and terpenes are chemical components of cannabis plants, also found in a variety of fruits and vegetables, that are just now being investigated for their therapeutic benefits. The results of those inquiries may prove useful for similar patients suffering from illnesses that are resistant to the usual treatments.
“Cannabis hyperemesis syndrome: still under-recognized after all these years“
After two years of chronic vomiting and pain and dozens of trips to emergency rooms a 23-year-old woman was found to have cannabis hyperemesis syndrome (CHS). Physicians are still unable to recognize the early symptoms of CHS as cannabis use is still in a legal gray area in much of the country. A lack of research, recognition, and trust often prevents a quick diagnosis when an illness is related to cannabis, leading to multiple referrals and invasive tests.
CHS was first described 15 years ago yet it is not frequently recognized in patients. The case study featured in this blog post highlights patients and physicians’ outcry for tolerance and support so that cannabis-related illnesses can be efficiently and effectively engaged.
In October 2018, recreational cannabis became legal in Canada. And in 2019, researchers asked nearly 20 thousand Canadians over the age of 15 about their cannabis habits. The survey found that 1 in 5 Canadians plan on trying or increasing cannabis use following legalization for non-medical purposes, particularly those who are younger, who have used cannabis in the past 3 months, and who have a higher income. To ensure responsible cannabis use and informed decision-making, clinicians and policy-makers should pay close attention to these higher risk populations.
In a study of 2,970 cancer patients, researchers determined that cannabis as a palliative treatment seems to be well tolerated, effective and a safe option to help patients cope with cancer-related symptoms.
Statistics show that in the past 15 years, the number of pregnant women using marijuana, especially in their first trimester, has risen greatly. These numbers may be slightly skewed, but they show the importance of more research being done on the effect of cannabis on pregnant women. https://cnn.it/2WWQV1e
Out of 2,835 high school students from North Carolina, 272 students (or 9.6%) reported ever vaping cannabis. Interestingly, the odds of ever vaping cannabis were significantly higher among males (11.0%) compared with females (8.2%), and significantly higher among non-Hispanic white students (11.3%) compared with non-Hispanic black students (5.0%).
It’s clear that white males are the most likely to have ever vaping cannabis. Why might minority students engage less with recreational drug use?

This 2018 review summarizes the available data regarding the safety and effectiveness of medical cannabis in young ASD patients. Here’s our video adaptation:
Autism spectrum disorder (ASD) defines a group of neurodevelopmental disorders that are frequently associated with general cognitive deficits
DSM-5 criteria of ASD include:
A. Persistent deficits in social communication and social interaction
B. Restricted, repetitive patterns of behavior, interests, or activities
C. Symptoms must be present in the early developmental period
D. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
E. These disturbances are not better explained by intellectual disability or global developmental delay
ASD is frequently accompanied by co-morbidities:
attention-deficit/hyperactivity disorder (ADHD)
mood and cognitive disorders
Despite it being one of the most severe chronic childhood disorders with relatively high prevalence, morbidity and impact on the society, no effective treatment for the core symptoms of ASD is available yet.
There is increasing interest in cannabinoids, especially cannabidiol (CBD), as monotherapy or add-on treatment for the core symptoms and co-morbidities of ASD.
CBD Use for Epilepsy
20-30% of people with ASD also suffer from epilepsy
Surveys conducted among parents of children suffering from epilepsy suggest improvement following treatment with CBD-enriched cannabis extracts. These results however, do not necessarily apply when it comes to treating adults with epilepsy (Alexander et al., 2009).
Still, in a retrospective study that examined the effect of CBD enriched medical cannabis oil on children with intractable epilepsy, the treatment caused a reduction in seizure frequency in 89% of patients (Tzadok et al., 2016).
CBD Use in Psychiatry
CBD in Psychosis
In some cases, psychosis can be a comorbidity of ASD, with the simultaneous onset of schizophrenia at adolescence or early adulthood (Sagar et al., 2013).
A 2006 study that investigated the influence of CBD as monotherapy in treatment-resistant schizophrenia found that it was ineffective (Zuardi et al., 2006).
But a 2018 study showed that, in patients with schizophrenia, adding CBD to ongoing antipsychotic treatment resulted in greater antipsychotic activity and beneficial effects, as compared to placebo add-on (Mcguire et al., 2018).
CBD and Anxiety
Many ASD patients suffer from anxiety disorders that harm their quality of life (Gu, 2017; Haan et al., 2008; Perrin, 2011).
CBD may possess anxiolytic effects both in animals and humans (Bergamaschi et al., 2011).
When tested in humans, CBD showed an anxiolytic effect in patients that suffer from social anxiety disorder (SAD), contrary to THC that may induce anxiety (Devinsky et al., 2014).
CBD, mood and cognitive disorders
It was previously shown that a variety of psychiatric co-morbidities may occur in ASD patients, the most common one being mood disorders (Ghaziddin and Zafar, 2008).
Risks of THC
THC use may be associated with onset or aggravation of depression, bipolar disorder, mania and psychosis (Rong et al., 2017).
THC administration may also result in memory impairment (Ranganathan and Souza, 2006; Rong et al., 2017).
Benefits of CBD
On the other hand, CBD possesses agonistic activity at the 5-HT1A serotonin receptor and shares similar mechanisms with lithium. These pharmacological properties may indicate its potential role in the treatment of mood disorders (Rong et al., 2017).
Therapeutic CBD properties were investigated for cognitive deficits as well. In a preclinical study that tested the effect of CBD on cognition in an Alzheimer’s Disease mouse model (APPxPS1), chronic CBD treatment reversed the cognitive deficits without affecting anxiety-related behaviors (Cheng et al., 2014).
CBD and sleep disorders
Sleep disorders are highly prevalent among children with ASD.
In the general population insomnia is the most common sleep complaint, and treatment with medical cannabis may be effective, especially when the insomnia is associated with pain (Gates et al., 2014).
It has been claimed that long term use of cannabis may induce sleep disturbances (Gates et al., 2014). however, a case series indicated that CBD treatment may actually improve the quality of sleep in Parkinson’s disease (Chagas et al., 2014).
CBD and ADHD
ADHD is one of the most common psychiatric co-morbidities in young ASD patients (Ghaziddin and Zafar, 2008), with comorbidity rates in the range of 40-70% (Antshel et al., 2016).
In a pilot randomized placebo-controlled experimental study of a cannabinoid medication (an oral spray containing 1:1 ratio of THC:CBD) in adults who suffer from ADHD, there was no significant improvement in the cognitive performance, but there was a significant improvement in the hyperactivity, impulsivity and inhibition measures after the treatment with the medical cannabis (Cooper et al., 2017).
The role of cannabis use for social behavior
Some studies show that THC administration may lead as well to a reduction in social interaction in rats, while co-administration of CBD seems to attenuate this effect (Malone et al., 2009).
On the other hand, in a study that tested the influence of marijuana smoking on healthy human volunteers, subjects reported retrospectively that while smoking marijuana they were happier, friendlier and calmer, responded more warmly to others, seemed to have a better understanding of their peers’ state of mind and were less likely to respond angrily or defensively. However, they had a harder time focusing and paying attention to what others said (Galanter et al., 1974).
CBD Use for Children
The administration of cannabinoids for children and adolescents suffering from ASD is a controversial legal and ethical issue (Khalil, 2012).
Those who oppose the use of medical cannabis in pediatrics claim that this treatment might harm young children and adolescents’ brain development.
In the field of pediatric mental illnesses, CBD is sometimes used as a treatment for anxiety disorders. In a case report describing a 10-year-old girl who suffered from PTSD after being sexually abused, it was reported that CBD treatment reduced her anxiety and improved her sleep (Shannon, 2016).
The use of cannabinoids in general and CBD in particular in the treatment of numerous medical and mental conditions, including ASD, is growing rapidly.
There certainly is a big gap in the field and such studies are needed before drawing any conclusions on the potential therapeutic applications of cannabinoids in ASD.
Further pre-clinical and clinical studies are needed in order to examine the pros and cons of CBD and other cannabinoids in ASD, before they are established as a treatment for ASD symptoms and co-morbidities.
Training and Practices of Cannabis Dispensary Staff
How much medical training does your local budtender possess? An online survey sent to medical marijuana dispensary staff reported only 55% of staffers had any formal training for their position, with 20% reporting some background in medical/scientific training. The analysis reported that many among the dispensary staff are recommending cannabis choices that are consistent with current evidence, but some are recommending strains that are either ineffective or exacerbate a patient’s condition. The findings of this study stress the importance of consistent and well-regulated training of dispensary staff.
Preferences for Medical Marijuana over Prescription Medications Among Persons Living with Chronic Conditions: Alternative, Complementary, and Tapering Uses
In a survey of 30 patients using medical cannabis for a range of illnesses, including Rheumatoid Arthritis, cancer, Hepatitis C, PTSD, and more, patients reported an array of benefits from their cannabis use. Patients successfully used cannabis as an alternative to prescription medication, as a complementary agent with traditional prescription medicines, and to gradually help halt the use of some prescription medications. Benefits described by participants included the effects of cannabis lasting longer than that of opioids, lower risk of addiction, fewer side-effects. Patients also saw their sleep, anxiety, appetite, and adverse reactions improve with the use of medical cannabis. Larger, more controlled studies may suggest cannabis more affirmatively as an alternative or complementary therapy with prescription medications.
