The National Drug Treatment Reporting System (NDTRS) published its latest figures on treated problem drug use (excluding alcohol) in May 2018.¹ These figures exclude those who reported alcohol as their primary problem substance as this will be reported in a separate bulletin. In the seven-year period, 2010—2016, 63,187 cases were treated for problem drug use (excluding alcohol). The number of cases increased from 8,806 in 2010 to 9,227 in 2016.
