Drug craving is a subjective motivation where users feel they want to go back to using narcotics. Drug craving is closely related to relapse. Rehabilitation carried out will be in vain when the abuser has stopped using narcotics but then reuse (relapse), so it is important to know what factors can influence drug craving. This study aims to examine the effect of the severity of addiction and abstinence self efficacy on drug craving in drug abusers. In this study, there were 100 stimulant narcotics abusers who were running a rehabilitation program somewhere. Data were analyzed using multiple regression analysis. The results showed that there was a significant effect of addiction severity and abstinence of self efficacy on drug craving with a significant value of 0.000 (p <0.05).
