Asthma in opiate addicts

A case-note study of 2276 opiate addicts revealed that 112(5%) had a history of asthma and that in 31(1.4%) cases there appeared to be a definite temporal relationship between heroin abuse and the onset of asthma. This rarely-reported complication of heroin dependence has a higher incidence among female addicts (3.3%) than among male addicts (0.7%).
