Objective: Lipids may play some roles in the central nervous system functions that are associated with drug addiction. To date, cholesterol is known to influence relapse of cocaine use. However, the relationship between cholesterol and heroin craving is unclear. This study examined the concurrent association between cholesterol and craving. Method: The serum lipid levels of 70 heroin users who were undergoing or had undergone a methadone maintenance therapy were measured. Their craving and demographic data were assessed. Results: Total cholesterol and low-density lipoprotein cholesterol are negatively associated with craving before (r = -0.33, P < 0.01, and r = -0.36, P < 0.01, respectively) and after controlling for the effects of potential confounders (β = -0.38, P < 0.01, and β = -0.42, P < 0.01, respectively). Conclusions: Cholesterol could be associated with the cognitive aspect of craving and may be a potential marker to predict risk of drug relapse.
