Poor sleep quality as a risk factor for lapse following a cannabis quit attempt.

Treatments for cannabis dependence are associated with high rates of lapse/relapse, underscoring the importance of identifying malleable risk factors that are associated with quit failure. Whereas research has demonstrated that poor sleep quality following cannabis discontinuation is related to subsequent use, there has yet to be an examination of whether poor sleep quality prior to a quit attempt results in a similar pattern of lapse. The present study addressed this gap by examining the role of pre-quit sleep quality on early lapse to cannabis use following a self-guided quit attempt, among 55 cannabis dependent military veterans. Results indicated that participants who experienced poor pre-quit sleep quality had greater risk for lapse within the first 2 days (out of 7) following their quit attempt. Findings are discussed in terms of improving treatments for individuals who report poor sleep quality prior to a cannabis quit attempt. Published by Elsevier Inc.
