As an alternative, the “both/or” precept is utilized with out differentiation. Nonetheless, this strategy isn’t coated by the necessities of the regulation and IQWiG’s fee, and the scientific literature additionally distinguishes between extreme and fewer extreme types of tobacco dependence. The G-BA, because the decision-making physique of the joint self-government of the German well being care system, in the end discusses and decides which medication for people who smoke with extreme tobacco dependence might be reimbursed by the SHI system. To this finish, the G-BA should additionally outline standards for when somebody is taken into account to be severely hooked on tobacco.

Following the commenting process, the report was revised and despatched to the G-BA as a ultimate report in December 2023.
