Problem drug use is associated with excess risk of infectious and other somatic diseases resulting mainly from injecting drug use. At the end of 2013, a complete medical history and physical examination was done in 40 problem drug users (30 males and 10 females), mean age 35.5 years (37.0 and 30.9, respectively), recruited in 4 low-threshold facilities in Prague.
Of them, 37 were ex- or active injecting drug users, predominantly of methamphetamine (pervitin) and less often of buprenorphine.
