The study was supported by the Health Foundation, the REDD-PAC projekt (REsearching Dual diagnosis—Prognosis And Characteristics) grant number 19-A-0042.

The authors report no conflicts of interest.

The study shed light on the long-run developments on the labor market and that the aggregate self-support of patients with a concurrent substance use and mental health disorder is halved in 20 years. Hence, these patients may have unused potential for recovery in terms of contributing to the society.
