In 33 states, along with the District of Columbia and Puerto Rico, however, people can legally buy and use medical cannabis for certain approved conditions, such as seizures and sleep problems, although the list of qualifying conditions varies by state. These same states, plus 13 others, also allow CBD oil. Fourteen states plus Puerto Rico have approved medical marijuana for autism, and some additional states may allow it for autistic people at a doctor’s discretion.
In many states where medical marijuana is legal, licensed dispensaries sell products that have been tested by accredited laboratories to verify the presence of active ingredients and the absence of contaminants. Some states permit individuals or their licensed caregivers to grow their own cannabis plants for personal use. Most states in the U.S. require people who use medical marijuana to register and get a special identification card.
Are there any cannabis-derived drugs approved to treat autism or related conditions?
To date, the U.S. Food and Drug Administration has approved only one cannabis-derived drug: Epidiolex. It is a liquid cannabis extract containing purified CBD that can decrease seizures in people with Dravet syndrome or Lennox-Gastaut syndrome — severe forms of epilepsy that are sometimes accompanied by autism — and in those with tuberous sclerosis complex. It is available only by prescription, and only for these three conditions.
The results of the study were encouraging. Most of the children involved saw improvement in anxiety, anger, and hyperactivity.
Children with autism grow and learn every day, simply because they are maturing. As a result, there is no simple way to determine whether a change in behavior or an increase in skills is due to a particular treatment or to ordinary maturation. This reality makes it very easy to see a change in behaviors and inaccurately attribute them to the newest treatment you've tried. By far, the best way to know whether a particular treatment is truly effective is to be rigorous about evaluating your child before and after its use.
A few full-scale studies have explored the impact of CBD on children with autism—none, however, have explored its impact on adults on the spectrum. One of the largest such studies took place in Israel. The report includes the following finding:
In addition (and perhaps as a result), they also saw significant improvements in social communication, sleep, and self-injury (a small percentage, however, worsened with treatment). A tremendous bonus is the fact that there were few side effects, and those that did appear (sleepiness and change in appetite) were mild.
Claims for CBD range from the realistic to the absurd. Some websites and companies claim, for example, that CBD can cure cancer (it can’t). On the other hand, CBD does seem to alleviate some untractable symptoms of disorders such as epilepsy, sleeplessness, and anxiety—all common issues for people with autism. According to Harvard Health Publishing, “the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications.”
Given all of the positive findings for CBD and the low risk associated with it, it may make sense to try using it with your child with autism (or trying it yourself if you are an adult with autism). Before buying a bottle of CBD oil, however, it's important to follow these steps:
For example, it may cause better sleep and lower anxiety (which can reduce aggressive behaviors), fewer seizures (which can lessen stress and make it easier to interact socially), and lower anxiety to make it easier to learn and use social communication skills.
