Cannabis Use Disorder Treatment

Introduction to Treatment Options

• The American College of Physicians recommends evidence-based alternatives to marijuana use, including FDA-approved synthetic cannabinoids like nabilone for those with withdrawal symptoms, behavioral therapies such as cognitive-behavioral therapy, and medication-assisted treatments tailored to the specific reasons for cannabis use 1

Pharmacological Options

• Synthetic cannabinoids, such as nabilone and nabiximols, are recommended for patients with withdrawal symptoms who previously consumed high-THC cannabis, as they can reduce withdrawal symptoms and cannabis craving, according to the British Journal of Anaesthesia 2
• Gabapentin carries a risk of dependence and withdrawal symptoms with prolonged use, and a gradual taper is necessary when discontinuing the medication to prevent withdrawal symptoms, as suggested by The Lancet Psychiatry and other sources 3, 4
• Dose adjustments are needed for patients with kidney dysfunction, and elderly patients may require slower tapering schedules and should be monitored closely 4

Supportive Interventions

• Referral to psychiatry or addiction medicine specialists is recommended for patients with severe withdrawal, and medical supervision is necessary for patients with high consumption levels to avoid abrupt discontinuation of use, according to the British Journal of Anaesthesia 2
• Monitoring for co-occurring mental health conditions that may be exacerbated during withdrawal is essential, as suggested by the British Journal of Anaesthesia, the Journal of Clinical Oncology, and other sources 2, 5

Behavioral Therapies

• Behavioral therapies, such as cognitive-behavioral therapy, contingency management, and motivational enhancement therapy, have shown effectiveness in treating problematic cannabis use, as reported by the Annals of Internal Medicine 6
• Psychoeducation about withdrawal symptoms and their time course, and supportive counseling as first-line approach are essential components of cannabis withdrawal management, according to the British Journal of Anaesthesia and other sources 2, 5

Harm Reduction Strategies

• Opioid substitution should be avoided, as opioids carry higher risks of dependence and overdose, according to Gastroenterology 7
• The likelihood of experiencing withdrawal symptoms depends on cannabis consumption patterns, with high risk associated with consuming >1.5g/day of inhaled cannabis, >300mg/day CBD-dominant oil, or >20mg/day THC-dominant oil, moderate risk with using cannabis products with unknown CBD/THC content more than 2-3 times per day, and low risk with consuming ≤300mg/day of smoked CBD-dominant cannabis, as outlined in the following table:

• Cannabis withdrawal syndrome occurs 24-72 hours after cessation of prolonged or heavy cannabis use, with symptoms typically peaking in the first week and lasting 1-2 weeks, and is characterized by symptoms such as irritability, anxiety, insomnia, decreased appetite, restlessness, altered mood, and physical symptoms like abdominal pain, tremors, sweating, fever, chills, and headache 2
