Cannabidiol for Reducing Cigarette Use

Description

The goal of this research is to evaluate the efficacy of cannabidiol (CBD) in reducing cigarette smoking. Although there are safe and effective treatments for smoking cessation, not everyone who attempts smoking cessation is successful, even with these treatments. Relapse rates are high, leaving a need for new approaches. Despite justification to evaluate CBD for this indication, human research on the topic is scant. Larger, more extended studies are warranted and essential. The investigators will recruit participants from CRI-Help, Inc., a substance abuse treatment program in North Hollywood, where residents who indicate the desire to stop smoking are prohibited from using other cannabis products which would affect recruitment. The aims of this study are: 1. Evaluate the effects of CBD on changes in cigarette use throughout and following the trial. 2. Exploratory Aims. Measure plasma concentrations of CBD, N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG) throughout the trial. Participants who meet eligibility criteria will take part in a 56-day treatment phase during which they receive the study medication under supervision (CBD or placebo twice daily) and complete questionnaires on side effects, withdrawal, craving and mood symptoms. Blood, breath, and urine tests will also be performed throughout the study. Participants who complete the treatment will also be assessed at 1-month and 3-month follow up visits.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Physiological dependence on alcohol or any drug, requiring medical detoxification and/or showing signs of acute withdrawal symptoms from opioids, alcohol or benzodiazepines.
  • * Treatment of Opioid Use Disorder with buprenorphine or methadone to avoid potential drug-drug interactions. CBD interacts with CYP3A. Opioid drugs metabolized by cytochrome P450 (CYP450), and cytochrome P450 isoenzyme CYP3A4 (CYP3A4) in particular, include fentanyl, methadone, oxycodone, and buprenorphine.
  • * Meeting DSM-5 criteria for schizophrenia, Bipolar I disorder, psychotic disorder, having active suicidal ideation, or suicide attempt in the past 12 months. NOTE: Participants with other psychiatric conditions, such as major depression, generalized anxiety, dysthymia, social phobia or specific phobia can enroll if they are clinically stable.
  • * AIDS or current HIV medication treatment with antiviral and/or non-antiviral therapy (due to the interaction of CBD with antiviral therapy).
  • * Clinically significant abnormalities on EKG (such as evidence of arrhythmia or MI).
  • * Clinically significant cardiovascular, hematologic, hepatic, renal, neurological, or endocrine abnormalities \[specific
