Evaluating Responses to Drug-Related Cues Versus Neutral Cues to Understand the Effects of Marijuana Craving - 1

June 1, 2012 updated by: Leslie Lundahl, Wayne State University

Cue Reactivity Model for Assessing Pharmacologic Intervention in Treatment of Cannabis Use Disorders (Study 1)

The majority of past research on marijuana treatment has specifically targeted the alleviation of withdrawal symptoms. Minimal focus has been placed on how altering craving effects may play a role in treating marijuana addiction. The purpose of this study is to compare the effects of marijuana-related cues versus non marijuana-related cues in individuals both addicted and not addicted to marijuana. In turn, this may help establish a better understanding of the effects of marijuana cravings and may lead to improved treatments for marijuana dependence.

Detailed Description

Marijuana is the most commonly used illegal drug in the United States; more than 2 million Americans either abuse or are dependent on the drug. The development of a medication to reduce marijuana use and prevent drug relapse by lessening withdrawal symptoms has been a primary focus of research. However, there has been little emphasis on evaluating the efficacy of a treatment that specifically reduces marijuana cravings. This study will evaluate the subjective and physiological responses to marijuana-related cues versus non marijuana-related cues in order to better understand the effects of marijuana cravings.

Participants will be divided into two groups. Group 1 will consist of 20 individuals diagnosed with marijuana dependence; Group 2 will consist of individuals matched by age range, gender and race to Group 1, and who are healthy volunteers and do not use marijuana or who report limited marijuana exposure. Participants in Group 1 will spend one night at the Psychiatric and Addiction Research Center at Detroit Receiving Hospital to control for alcohol and drug use for 12 hours preceding the next day's 2-hour study session. Participants in Group 2 are not required to spend the night, but are tested for drugs and alcohol prior to the session. During the study session, both groups will be shown a nature video and will be asked to handle and smell various items; these will act as the neutral, non marijuana-related cues. Next, the participants will watch a video of individuals smoking marijuana and will be asked to handle and smell marijuana-related items; these will act as the marijuana-related cues. Heart rate and skin temperature will be monitored continuously throughout the cue sessions with the use of electrodes and a skin thermometer. Prior to and after the cue sessions, blood pressure will be measured and questionnaires will be administered to assess drug cravings as well as related mood states. Prior to leaving the laboratory, the participants' vital signs will be evaluated to ensure that any cue-related physiological changes have returned to normal. Participants will have the option of talking to a clinician experienced in dealing with drug cravings following the end of the study session.
