Desomorphine has a rapid onset and a brief duration of action. Limited animal WebHeroin (diacetyl-morphine or diamorphine), in turn, is rapidly deacetylated to 6-monoacetylmorphine (6MAM), then further metabolized into morphine. Both 6MAM and morphine are bioactive metabolites. In fact recent evidence suggest that 6MAM could have a major role mediating heroin effects (Gottås et al., 2013).
