Effects of drug abuse

Share Your Story Drug abuse and addiction, now both grouped as drug use disorder, is a condition that is characterized by a self-destructive pattern of using a substance that leads to significant problems and distress, which may include tolerance to or withdrawal from the substance.

Effects of drug abuse

In light of the rapidly evolving interest in the potential use of marijuana and its derivative compounds for medical purposes, it is important to take stock of what we know and do not know about the therapeutic potential of CBD.

Background To date, 23 states and the District of Columbia have passed laws allowing marijuana to be used for a variety of medical conditions. Interest in the potential therapeutic effects of CBD has been growing rapidly, partially in response to media attention surrounding the use of CBD oil in young children with intractable seizure disorders including Dravet syndrome and Lennox-Gastaut syndrome.

While there are promising preliminary data, the scientific literature is currently insufficient to either prove or disprove the efficacy and safety of CBD in patients with epilepsy. In addition to epilepsy, the therapeutic potential of CBD is currently being explored for a number of indications including anxiety disorders, substance use disorders, schizophrenia, cancer, pain, inflammatory diseases and others.

My testimony will provide an overview of what the science tells us about the therapeutic potential of CBD and of the ongoing research supported by NIH in this area. CBD has a very low affinity for these receptors fold less than THC and when it binds it produces little to no effect.

There is also growing evidence that CBD acts Effects of drug abuse other brain signaling systems, and that these actions may be important contributors to its therapeutic effects. Anti-Seizure Effects A number of studies over the last two decades or more have reported that CBD has anti-seizure activity, reducing the severity of seizures in animal models.

Three of the four studies reported positive results, including decreased frequency of seizures. However, the studies suffered from significant design flaws, including failure to fully quantify baseline seizure frequency, inadequate statistical analysis, and a lack of sufficient detail to adequately evaluate and interpret the findings.

In addition, clinical trials are currently underway by GW Pharmaceuticals, testing the efficacy of Epidiolex, a purified CBD extract, for treatment of pediatric epilepsy. It has not been approved in the United States, but clinical trials are ongoing, and two recent studies reported that nabiximols reduced the severity of spasticity in MS patients.

However, the current evidence suggests that the analgesia is mediated by THC and it is unclear whether CBD contributes to the therapeutic effects. However, the anti-inflammatory properties of CBD discussed above could be predicted to play a role in the analgesic effects of nabiximols.

Recent research has also suggested that cannabinoids and opioids have different mechanisms for reducing pain and that their effects may be additive, which suggests that combination therapies may be developed that may have reduced risks compared to current opioid therapies.

However, this work is very preliminary. There are multiple industry sponsored clinical trials underway to begin to test the efficacy of CBD in human cancer patients. Anti-Psychotic Effects Marijuana can produce acute psychotic episodes at high doses, and several studies have linked marijuana use to increased risk for chronic psychosis in individuals with specific genetic risk factors.

Research suggests that these effects are mediated by THC, and it has been suggested that CBD may mitigate these effects. Anti-Anxiety Effects CBD has shown therapeutic efficacy in a range of animal models of anxiety and stress, reducing both behavioral and physiological e.

CBD reduced anxiety in patients with social anxiety subjected to a stressful public speaking task. CBD reduced the rewarding effects of morphinexxxviii and reduced cue-induced heroin seekingxxxix in animal models.

NIDA is supporting multiple ongoing clinical trials in this area. A review of 25 studies on the safety and efficacy of CBD did not identify significant side effects across a wide range of dosages, including acute and chronic dose regimens, using various modes of administration. Because of this, there is extensive information available with regard to its metabolism, toxicology, and safety.

However, additional safety testing among specific patient populations may be warranted should an application be made to the Food and Drug Administration. Research Opportunities and Challenges This is a critical area for new research. While there is preliminary evidence that CBD may have therapeutic value for a number of conditions, we need to be careful to not get ahead of the evidence.

Ninety-five percent of drugs that move from promising preclinical findings to clinical research do not make it to market.

The recently announced elimination of the PHS review of non-federally funded research protocols involving marijuana is an important first step to enhance conducting research on marijuana and its components such as CBD. Still, it is important to try to understand the reasons for the lack of well-controlled clinical trials of CBD including: Furthermore, the opportunity to gather important information on clinical outcomes through practical non-randomized trials for patients using CBD products available in state marijuana dispensaries is complicated by the variable quality and purity of CBD from these sources.

Ongoing CBD Research The NIH recognizes the need for additional research on the therapeutic effects of CBD and other cannabinoids, and supports ongoing efforts to reduce barriers to research in this area.

Effects of drug abuse

NIH is currently supporting a number of studies on the therapeutic effects as well as the health risks of cannabinoids. These include studies of the therapeutic value of CBD for: For example, studies related to epilepsy will likely be funded by the National Institute of Neurological Disorders and Stroke or by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, while studies related to schizophrenia will likely be funded by the National Institute on Mental Health.

Conclusion There is significant preliminary research supporting the potential therapeutic value of CBD, and while it is not yet sufficient to support drug approval, it highlights the need for rigorous clinical research in this area. There are barriers that should be addressed to facilitate more research in this area.

We appreciate the opportunity to testify on the potential use of CBD for therapeutic purposes. Thank you again for inviting me here today, and I look forward to any questions you may have.
