"The NAOMI study provided injectable HDM to a small group of participants. An unexpected finding was that many participants couldn’t tell the difference between the effects of diacetylmorphine and HDM.

"However, the small number of participants receiving HDM did not permit researchers to draw any definite and scientifically valid conclusions as to the efficacy of HDM as a treatment option.

"Therefore, the SALOME investigators designed a study to test this hypothesis.

"SALOME aimed to determine alternative treatments for people with chronic heroin addiction not benefitting sufficiently from available treatments such as oral methadone."
