Participants in the intervention group have access to short-term and long-term interventions, whereas those in the control group only have access to the weekly ecological momentary assessment reports. Participants in the intervention group are able to access the intervention materials 5 days after enrollment and receive weekly ecological momentary assessment reports. Those in the control group will be granted access to all intervention materials after five weeks following study enrollment. A questionnaire battery assessments is administered (1) at baseline in the first week following onboarding in; (2) after 5 weeks; (3) after six months. In addition, longitudinal data on several variables related to craving and lapse risk are collected daily using ecological momentary assessment
