About this study

Official title: Mobile Contingency Management for Concurrent Abstinence From Cannabis and Cigarette Smoking: A Pilot Study

The purpose of this pilot project is to pilot-test a combined cannabis and smoking cessation treatment. The intervention combines mobile technology with behavioral strategies, counseling, and medications.

Read the detailed description

Cannabis is the most widely used illicit drug in the United States with 19.8 million current users. Population based data indicate that almost all cannabis users (90%) have a lifetime history of tobacco smoking and the majority (74%) currently smoke tobacco. While cannabis use alone is associated with significant adverse health effects, tobacco smoking is the number one preventable cause of illness and death in the U.S. This is true even among those using illicit drugs where the tobacco -related mortality rate is twice that of the general population. Among cannabis users, smoking tobacco is associated with increased frequency of marijuana use, increased morbidity, and poorer cannabis cessation outcomes. There is strong evidence for the short -term efficacy for cannabis use disorder (CUD) and smoking of contingency management (CM). It is an intensive behavioral therapy that provides incentives (vouchers, money) to individuals misusing substances contingent upon objective evidence from drug use. Implementation of CM has been limited because of the need to verify abstinence multiple times daily using clinic based monitoring and effects are short lived. The investigators recently developed a smart -phone application which allows a patient to video themselves several times daily while using a small CO monitor and to transmit the data to a secure server which has made the use of CM for outpatient smoking cessation portable and feasible. The mobile CM (mCM) approach paired with cognitive-behavioral counseling and pharmacological smoking cessation aids has been effective in reducing smoking in the short and long-term. The purpose of this pilot project is to pilot-test a combined cannabis and smoking mCM intervention. The pilot will allow the investigators to examine feasibility of the treatment and of planned recruitment strategies. These project aims will provide the first step toward implementation of an innovative approach that builds upon the power of mHealth technology to reduce the prevalence of both CUD and cigarette smoking.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Self-report Prolonged Abstinence From Smoking

    Participants self-report smoking behavior since smoking quit date. Prolonged abstinence is defined as sustained abstinence since two weeks post-initial smoking quit date.

    Measured: 6 month follow up

  2. Number of Participants Who Report Smoking Abstinence and Abstinence is Bioverified by Salivary Cotinine

    Self-reported abstinence (primary outcome) will be verified by cotinine assay. Saliva samples will be collected from participants who self-report prolonged abstinence.

    Measured: 6 month follow up

  3. Number of Participants Who Self-report Prolonged Abstinence From Marijuana Use

    Participants self-report marijuana use since marijuana quit date. Prolonged abstinence is defined as sustained abstinence since two weeks post-initial quit date.

    Measured: 6 month follow up

  4. Number of Participants Who Report Marijuana Abstinence and Abstinence is Bioverified by Oral Fluid

    Self-reported abstinence (primary outcome) will be verified by oral fluid (OF) cannabis assessment. Oral fluid samples will be collected from participants who self-report prolonged abstinence.

    Measured: 6 month follow up

Secondary outcomes (15)
  1. Number of Participants Who Self-report 7 Day Point Prevalence Abstinence From Smoking

    7-day point prevalence abstinence is defined as no smoking in the prior 7 days.

    Measured: 6 month follow up

  2. Number of Participants Who Self-report 7 Day Point Prevalence Abstinence From Marijuana

    7-day point prevalence abstinence is defined as no marijuana use in the prior 7 days.

    Measured: 6 month follow up

  3. Number of Participants Who Report 30 Day Point Prevalence Abstinence From Marijuana

    30-day point prevalence abstinence is defined as no marijuana use in the prior 30 days.

    Measured: 6 month follow up

  4. Number of Participants Who Report 30 Day Point Prevalence Abstinence From Smoking

    30-day point prevalence abstinence is defined as no smoking in the prior 30 days.

    Measured: 6 month follow up

  5. Number of Participants Who Report 7 Day Point Prevalence Abstinence From Smoking

    7-day point prevalence abstinence is defined as no smoking in the prior 7 days.

    Measured: 3 month follow up

  6. Number of Participants Who Report 7 Day Point Prevalence Abstinence From Marijuana

    7-day point prevalence abstinence is defined as no marijuana use in the prior 7 days.

    Measured: 3 month follow up

  7. Number of Participants Who Report Smoking Abstinence and Abstinence is Bioverified by Salivary Cotinine

    Self-reported abstinence (primary outcome) will be verified by cotinine assay. Saliva samples will be collected from participants who self-report prolonged abstinence.

    Measured: 3 month follow up

  8. Number of Participants Who Report Marijuana Abstinence and Abstinence is Bioverified by Salivary Cotinine

    Self-reported abstinence (primary outcome) will be verified by oral fluid (OF) cannabis assessment. Oral fluid samples will be collected from participants who self-report prolonged abstinence.

    Measured: 3 month follow up

  9. Change From Baseline in Number of Days Per Week of Cannabis Use

    Participants will self-report amount of marijuana used in past week; this will be compared to self-reported amount smoked per week prior to quit date.

    Measured: baseline, 6 month follow up

  10. Proportional Change in Days of Cannabis Use From Pre-quit to 6 Month Follow-up (Entire Group)

    Participants will self-report number of days marijuana used in the past 30 days and this will be compared for the entire group to self-reported number of days of use in 30 days prior to quit. The proportion will be calculated by totaling baseline days used and pretreatment days used, and then dividing baseline days used by pretreatment days used.

    Measured: 30 days prior to quit date, 6 month follow up

  11. Change in Number of Cigarettes Smoked Per Week Compared to Pre-quit

    Self-reported number of cigarettes smoked each day in past 7 days; this will be compared to self-reported amount smoked in week prior to quit date

    Measured: 7 days prior to quit date, 6 month follow up

  12. Proportional Change in Days Smoked From Pre-quit to 6-month Follow up (for Entire Group)

    Participants will self-report number of days smoked in the past 30 days and this will be compared (for the entire group) to self-reported number of days smoked in 30 days prior to quit. The proportion will be calculated by totaling baseline days used and pretreatment days used, and then dividing baseline days used by pretreatment days used.

    Measured: 30 days prior to quit date, 6 month follow up

  13. Percentage of Missing Mobile Contingency Management Video Recordings

    Participants upload video recordings of abstinence verification as part of contingency management treatment. Percentage of missed videos (compared to expected videos) will be assessed as a measure of feasibility of the contingency management intervention

    Measured: 3 month follow up

  14. Number of Missed Behavioral Counseling Sessions

    Participants attend telephone counseling sessions. Number of missed sessions for the total group will be assessed as a measure of acceptability of the behavioral counseling

    Measured: 3 month follow up

  15. Number of Voluntary Withdrawals From the Project

    The number of participants who withdraw from the study will be evaluated as a measure of treatment feasibility and acceptability

    Measured: Evaluated at 6 month follow-up
