Brief Summary

In this study, the investigators seek to evaluate the effects of cannabidiol (CBD) on cocaine craving and relapse. Cocaine addiction is characterized by compulsive substance use and repetitive urges to consume the drug even after a sustained period of abstinence. While substance use remains the most obvious direct outcome of addiction, there is a growing interest in other core symptoms of this disorder. Craving has become a subject of great interest as it is a reliable intermediate phenotype of cocaine relapse and a distressing symptom of addiction associated with suffering. Indeed, even after a period of abstinence, cocaine-dependent individuals remain vulnerable to stress and other craving-inducing stimuli, which, in turn, lead to intense physiological responses and various negative feelings such as anger and sadness. Real-time daily monitoring of craving and drug use has shown that craving predicts cocaine relapse among cocaine-dependent individuals. In sum, working toward improving the treatment of craving could not only help prevent relapse, but also reduce patient distress on emotional, cognitive, and physiological levels. In the past decades, significant scientific efforts have been deployed toward the development of innovative strategies to beat cocaine addiction, but with partial success thus far. Psychosocial approaches have been widely used to help cocaine-dependent patients achieve better outcomes after drug cessation, but literature indicates that these strategies alone are at times insufficient to induce significant behavioural changes or a reduction in rates of drug consumption. Unlike other types of addiction, such as opioid and alcohol, no pharmacological treatment has yet been found to be truly effective in relieving cocaine-cessation symptoms like craving and anxiety or to prevent relapse. CBD is a natural cannabinoid with a favourable tolerability profile and discrete neurobiological actions that are linked to neural circuits closely involved in addiction disorders. Addiction to cocaine is characterized by alternating phases of intoxication and short abstinence, followed by recurrent drug-craving episodes which result in distress and relapse. Our hypothesis is that CBD a cannabinoid known for its broad spectrum properties is an interesting pharmacological contender to decrease cocaine craving and treat cocaine addiction. Previous studies conducted in animals and humans confirm that CBD is a very safe and tolerable medication.

Outcome Measures

Primary Outcomes (2)

  • Drug-cue induced craving

    A 10-point visual analog scale (VAS) used to measure craving responses in the context of cocaine cue-induced craving during the laboratory session on Day 8 of detoxification

    Day 8

  • Number of days to relapse

    The number of days to relapse will be determined as the number of days between detoxification discharge (Day 10) and the day of first cocaine use as determined by the first positive urine test for cocaine (the day prior to urine testing will be entered as the day of relapse) or the first day of cocaine use self-reported by participants (the earliest of both measures)

    Day 10 to 92

Secondary Outcomes (2)

  • Stress-induced craving

    Day 8

  • Cocaine use during the post-detoxification phase

    Day 10 to 92

Other Outcomes (22)

  • Detailed cocaine craving

    Day 1, Day 3, Day 5, Day 7, Day 9, Week 1, Week 3, Week 5, Week 7, Week 9, Week11

  • Subjective cocaine craving

    Day 1, Day 3, Day 5, Day 7, Day 9, Week 1, Week 3, Week 5, Week 7, Week 9, Week11

  • Cocaine withdrawal symptoms

    Day 1, Day 3, Day 5, Day 7, Day 9, Week 4, Week 8, Week 12

  • +19 more other outcomes

Study Arms (2)

Cannabidiol

ACTIVE COMPARATOR

Participants will receive CBD 800 mg for 92 consecutive days starting on Day 2 of a 10-day inpatient detoxification period followed by 12 weeks of outpatient follow-up

Drug: Cannabidiol

Placebo

PLACEBO COMPARATOR

Participants will receive placebo for 92 consecutive days starting on Day 2 of a 10-day inpatient detoxification period followed by 12 weeks of outpatient follow-up

Drug: Cannabidiol

Interventions

The investigators will carry out a double-blind, randomized, controlled trial comparing the effects of 92 days of 400 (only for the first 2 Days starting on the Day 2 of the study) or 800 mg CBD (subjects who report side effects with the 800mg dose will be administered the CBD 400 mg dose for the remainder of the trial) vs. placebo administration on cocaine craving and relapse in 110 cocaine-dependent subjects.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • DSM-5 criteria for current cocaine use disorder (moderate or severe).

  • Subject consents to inpatient detoxification at the CHUM.
  • Ability to give valid, informed consent.
  • Ability to speak and read French or English.

You may not qualify if:

  • Severe and/or unstable hepatic, neurologic (including diagnosis of seizures), cardiac (including arrhythmias) or renal disease), or any other severe or unstable medical condition that precludes safe participation in the study according to the study physician.
