THC for Cannabis Use Disorder
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how men and women with cannabis use disorder (CUD) respond to THC, the active ingredient in cannabis. Researchers examine THC's effects on brain activity and reward processing using brain scans. Participants will take either a THC capsule (Dronabinol) or a placebo in different sessions to compare effects. Ideal candidates are adults who use cannabis frequently, such as four or more days a week, and have CUD. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.
Do I have to stop taking my current medications for the trial?
Yes, you must stop taking any current psychotropic medications (drugs that affect your mind, emotions, or behavior) to participate in this trial.
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Research has shown that dronabinol, a synthetic version of THC, has been used safely in numerous studies. It aids individuals trying to quit cannabis by reducing withdrawal symptoms, easing the challenging side effects.
Some studies have found that dronabinol is generally well-tolerated. However, high doses might cause mood changes or feelings of anxiety, particularly if not used properly. In a clinical trial, where conditions are carefully controlled, the risk of such effects is lower. Additionally, the FDA has approved dronabinol for other uses, indicating its well-established safety.
Overall, dronabinol has been extensively studied and is generally safe when used as directed. Participants in clinical trials receive close monitoring, providing an extra layer of safety.12345Why do researchers think this study treatment might be promising for cannabis use disorder?
Dronabinol is unique because it uses a synthetic form of THC, the active ingredient in cannabis, to address cannabis use disorder. Unlike other treatments that often focus on behavioral therapy or abstinence, dronabinol targets the biological pathways involved in addiction by mimicking the effects of cannabis without the harmful components of smoking. Researchers are excited because this approach could help reduce withdrawal symptoms and cravings, offering a new avenue for those struggling to quit cannabis.
What evidence suggests that Dronabinol might be an effective treatment for cannabis use disorder?
In this trial, participants will receive either dronabinol, a man-made version of THC, or a placebo. Research has shown that dronabinol can help individuals with cannabis use disorder (CUD) reduce their self-reported cannabis use. Some studies found that it alleviates withdrawal symptoms like restlessness and upset stomach, making it easier for individuals to adhere to their treatment plans. However, dronabinol alone did not significantly reduce the likelihood of returning to cannabis use compared to a placebo. While it appears helpful for easing withdrawal and maintaining treatment adherence, the overall evidence for its effectiveness in reducing cannabis use remains mixed.16789

Trial Overview
The study is examining how THC affects reward processing in men and women differently. It uses brain imaging techniques to measure changes after taking either a placebo or Dronabinol (synthetic THC), which participants will receive on two separate occasions.
