Treatment for Cannabis Use Disorders: A Case Report
Introduction
Cannabis use disorder (CUD) has emerged as a significant public health concern, particularly in the context of increasing legalization and societal acceptance of cannabis use. While many individuals consume medical cannabis without developing problematic patterns, a substantial subset experiences adverse consequences that meet the diagnostic criteria for CUD.
CUD is characterized by a problematic pattern of cannabis use leading to clinically significant impairment or distress. This includes symptoms such as increased tolerance, withdrawal symptoms upon cessation, unsuccessful attempts to cut down or control use, and continued use despite social or interpersonal problems caused or exacerbated by cannabis.
The prevalence of CUD is notable. Studies indicate that approximately 9% of individuals who use cannabis will develop dependence, with higher rates among those who begin use during adolescence or engage in daily use. This underscores the need for effective identification and treatment strategies.
Despite the growing recognition of CUD, treatment options remain limited. Psychotherapeutic interventions, such as cognitive-behavioral therapy (CBT), motivational enhancement therapy (MET), and contingency management (CM), have demonstrated efficacy in reducing cannabis use and promoting abstinence. However, there are currently no FDA-approved pharmacotherapies for CUD, although research into medications like gabapentin and N-acetylcysteine shows promise.
This case report aims to provide a detailed examination of CUD through the lens of an individual patient's experience. By exploring the clinical presentation, diagnostic process, and treatment course, this report seeks to offer insights into the complexities of CUD and inform evidence-based approaches to management.

Given Mr. M's initial ambivalence about quitting cannabis, MET was employed to strengthen his motivation and commitment to change. This client-centered approach facilitated discussions about the pros and cons of cannabis use, helping him resolve ambivalence and set achievable goals for abstinence.
3. Contingency Management (CM):
To reinforce positive behaviors, CM was incorporated by providing tangible rewards for meeting specific treatment goals, such as negative urine drug screens. This approach leveraged positive reinforcement to encourage sustained abstinence and engagement in treatment.
Pharmacological Interventions
While no FDA-approved medications exist specifically for CUD, several off-label pharmacotherapies have shown promise in managing withdrawal symptoms and supporting abstinence.
1. Gabapentin:
Prescribed at 400 mg three times daily, gabapentin was selected to alleviate withdrawal symptoms, including insomnia, anxiety, and irritability. Studies have indicated its efficacy in reducing cannabis use and improving sleep quality during withdrawal.
2. N-Acetylcysteine (NAC):
Administered at 1200 mg twice daily, N-Acetylcysteine (NAC) was introduced to modulate glutamate levels in the brain, potentially reducing cravings and supporting abstinence. Research suggests that NAC may be particularly beneficial for individuals with CUD, aiding in the maintenance of long-term recovery.
3. Dronabinol and Naltrexone (Initial Consideration):
Initially, a combination of dronabinol (a synthetic THC) and naltrexone (an opioid antagonist) was considered to address withdrawal symptoms and prevent relapse. However, due to insurance constraints and cost considerations, this regimen was not pursued.
Monitoring and Support
Regular monitoring was integral to Mr. M's treatment plan. Weekly therapy sessions provided ongoing support, while periodic urine drug screens offered objective measures of abstinence. These tools facilitated early identification of potential relapses and allowed for timely adjustments to the treatment strategy.
Outcome and Adjustments
Over the course of treatment, Mr. M demonstrated significant progress. He reported improved sleep, reduced anxiety, and enhanced relationships with his family. His commitment to therapy and adherence to the pharmacological regimen contributed to sustained periods of abstinence.
Two instances of relapse were addressed promptly through therapy, focusing on identifying triggers and developing robust coping mechanisms. These episodes underscored the chronic nature of CUD and the importance of resilience and adaptability in treatment planning.
Mr. M's treatment journey highlights the effectiveness of an integrated approach combining psychotherapy and pharmacotherapy in managing severe CUD.
