The samples included children, adolescents, and adults, with varying proportions of CBD and THC in the cannabis products NCBI.

While some studies have reported improvements in behavioral aspects such as decreased bouts of self-mutilation, anger, hyperactivity, and sleep problems, it is important to note that the reported effects can vary. The efficacy, safety, and tolerability of cannabis products for individuals with ASD are still being researched.

It is also worth mentioning that the studies have reported mild to moderate side effects associated with cannabis products in individuals with ASD. These side effects include sleep disorders, restlessness, change in appetite, irritability, diarrhea, increased appetite, conjunctival hyperemia, behavioral problems, decreased cognition, fatigue, and aggression/agitation. However, the side effects were generally mild to moderate and transitory NCBI.

As research in this area progresses, it is crucial to conduct further clinical trials and studies to gain a comprehensive understanding of the efficacy, safety, and long-term implications of cannabis use in individuals with ASD. This will not only provide valuable insights but also help in establishing guidelines and recommendations for the use of cannabis as a potential therapeutic option for managing ASD symptoms.

Cannabis Use and ASD Risk

When considering the use of cannabis in individuals with Autism Spectrum Disorder (ASD), it is important to be aware of the potential vulnerabilities and long-term implications associated with its use.

Vulnerabilities in ASD Individuals

Research suggests that individuals on the autism spectrum may be particularly vulnerable to the pro-psychotic effects of cannabinoid exposure, increasing their risk of psychosis. Cannabis exposure among individuals with ASD can lead to disruptive epigenetic effects that may be inherited intergenerationally. This can have implications for brain areas critical to schizophrenia pathophysiology [3].

Autism and schizophrenia share common neurobiological underpinnings, with common psychotic symptoms similar to manifestations in ASDs. This suggests a potential developmental trajectory from autism to psychosis due to disruption in the endocannabinoid system. Autism candidate genes may be more vulnerable to subsequent disruption and possibly lead to psychosis onset later in life [3].

Long-Term Implications

The use of cannabis, particularly high levels of Δ-9-tetrahydrocannabinol (THC), can have long-term implications for individuals with ASD. Cannabis use can increase susceptibility to impaired learning, memory recall, and both negative and positive psychotic symptoms. Early, frequent, and/or continuous exposure to high-potency cannabis is associated with a higher likelihood of developing subtle psychotic symptoms or first episode psychosis (FEP) [3].

It is important to note that there is a lack of evidence examining the safety and efficacy of cannabis-based medications for ASD. While medical cannabis may be welcomed by families of individuals with ASD, mental healthcare professionals should proceed with caution due to the potential progression between ASD and schizophrenia with high THC exposure. Public education is also needed to warn against recreational cannabis use in adolescents and youth with ASD.

As research on the effects of cannabis use in individuals with ASD continues to evolve, it is crucial to advocate for further studies to better understand the potential risks and benefits. Mental healthcare professionals should stay informed about the latest research findings and exercise caution when considering cannabis use in individuals with ASD. Public education should emphasize the importance of evidence-based approaches and discourage recreational cannabis use in vulnerable populations.

Prenatal Cannabis Exposure

Prenatal cannabis exposure has been a topic of concern, particularly due to its potential impact on offspring and its association with Autism Spectrum Disorder (ASD) incidence. Understanding the effects of prenatal cannabis exposure is crucial in order to make informed decisions regarding cannabis use during pregnancy.

Effects on Offspring

Cannabis exposure during pregnancy has become more prevalent, with 3-7% of pregnant women in the USA reporting marijuana use [4]. However, health organizations advise against cannabis use during pregnancy due to concerns about adverse effects on neurodevelopment in offspring.

Research has shown a potential association between prenatal maternal cannabis use and the incidence of ASD in children. A study conducted in Ontario, Canada found that prenatal cannabis use was associated with an increased risk of ASD in children. The study included a large sample size of over 500,000 children and found an incidence of 4.0 per 1,000 person-years in the exposed group compared to 2.4 in the unexposed group.

It is important to note that the study did not differentiate between recreational and medicinal cannabis use. Understanding the type of cannabis use is crucial, as medical cannabis use may be associated with underlying conditions that could increase the risk of ASD.

Association with ASD Incidence

The study conducted in Ontario, Canada provided evidence of an association between prenatal cannabis exposure and the incidence of ASD in children. The incidence of ASD was found to be higher in the exposed group compared to the unexposed group, with a hazard ratio of 1.51 in the matched cohort after full adjustment [4].

It is worth mentioning that cannabis use during pregnancy is linked to other negative outcomes, such as a higher risk of fetal low birth weight, which in turn is identified as a risk factor for ASD. However, the study did not assess low birth weight as an intermediate step in the association between prenatal cannabis exposure and the risk of ASD.

It is important to consider the limitations of the study on prenatal cannabis exposure and ASD. The study faced challenges in measuring cannabis exposure, including limited data on the time, duration, frequency, dose, types of cannabis products, and administration routes. Additionally, the exposure was reported only during the first trimester of pregnancy, and data on continued cannabis exposure after birth was not available.

Further research is needed to better understand the relationship between prenatal cannabis exposure and ASD incidence. It is essential to advocate for more studies to gather comprehensive data on the effects of cannabis use during pregnancy. Additionally, healthcare professionals should provide guidelines on the potential risks associated with prenatal cannabis exposure to ensure the safety and well-being of both the mother and the child.

Recommendations and Future Research

As the topic of using marijuana for individuals with Autism Spectrum Disorder (ASD) continues to be explored, there is a need for further research and advocacy to better understand its potential benefits and risks. Two key areas of focus are advocating for further studies and addressing safety concerns and guidelines.

Advocacy for Further Studies

Various organizations and researchers advocate for additional studies to expand our knowledge of the effects of cannabis and its cannabinoids on individuals with ASD. The Autism Science Foundation, in collaboration with the American Academy of Pediatrics, supports further research on the safety and efficacy of medical marijuana in ASD and other childhood conditions. They recommend reclassifying medical marijuana from a Schedule I to a Schedule II compound to facilitate expanded research possibilities.

Additionally, randomized, double-blind, placebo-controlled clinical trials are necessary to provide more concrete evidence on the effects of cannabis and its cannabinoids on individuals with ASD. These trials can help determine the optimal dosages, potential side effects, and overall effectiveness of cannabis as a therapeutic alternative for alleviating ASD symptoms. The need for consistent evidence on efficacy, safety, and tolerability highlights the importance of further research in this field [2].

Safety Concerns and Guidelines

While the potential benefits of cannabis for individuals with ASD are being explored, it is essential to address safety concerns and establish guidelines. There is currently a lack of evidence examining the safety and efficacy of cannabis-based medications specifically for ASD. Mental healthcare professionals should exercise caution regarding the potential progression between ASD and schizophrenia due to high THC exposure. Public education is also necessary to warn against recreational cannabis use in adolescents and youth with ASD.

Developing comprehensive guidelines for the use of cannabis in ASD is crucial to ensure the well-being and safety of individuals with ASD. These guidelines should consider factors such as appropriate dosages, potential interactions with other medications, and monitoring for potential adverse effects. Continued research and collaboration between medical professionals, researchers, and advocacy groups can help establish evidence-based guidelines that prioritize the health and safety of individuals with ASD.

As the field of cannabis and ASD continues to evolve, ongoing research and advocacy efforts are essential to provide the necessary evidence and guidance for informed decision-making regarding the use of cannabis in individuals with Autism Spectrum Disorder.
