"The North American Opiate Medication Initiative (NAOMI) is a carefully controlled (clinical trial) that will test whether medically prescribed heroin can successfully attract and retain street-heroin users who have not benefited from previous repeated attempts at methadone maintenance and abstinence programs.

"The NAOMI study will enroll 470 participants at three sites in Vancouver, Montreal and Toronto. The Toronto and Montreal sites are expected to begin recruitment this spring.

"Each site will enroll about 157 participants. About half of these volunteers will be assigned to receive pharmaceutical-grade heroin (the experimental group) and half will receive methadone (the control group). The prescribed heroin will be self-administered under careful medical supervision within a specially designed clinic. Those in the heroin group will be treated for 12 months then transitioned, over three months, into either methadone-maintenance therapy or another treatment program. The researchers expect a 6-9 month recruitment period, so that the total time to complete the study will be 21 to 24 months."
