TABLE 1.

Relative weights of harm dimensions, as determined by German addiction experts, patients, and EU experts.

Dimension	EU-rating* (Experts, n = 40)	Experts** (n = 36)	Patients (user)** (n = 44)
		Mean (SD) in %	Mean (SD) in%
Physical harm to user	25.9	25.0 (7.0)	21.3 (9.6)
Psychological harm to user	16.0	23.5 (6.6)	28.3 (13.2)
Social harm to user	11.2	20.1 (7.5)	23.9 (12.6)
Physical & psychological harm to others	11.6	13.0 (4.4)	14.1 (7.4)
Social harm to others	35.5	18.3 (7.7)	12.3 (7.5)

Weights add up to 100%. *Consensus-based (8), **ad hoc, clearly different estimations are marked by gray background. The calculation of the overall harm of the substances by using these relative weights are shown in the Supplementary material 2.2.
