Opium consumption was found to be relatively high in the RCS participants, especially in men (men\u2009=\u20092150 and women\u2009=\u2009228). Opium use was associated with a higher odds of IHD and MI, with the adjusted odds ratios (95% CI) of 1.51 (1.22\u20131.86) and 1.79 (1.31\u20132.45), respectively.
