"In Spain, the legal framework of the methadone maintenance programmes (MMPs) is regulated by way of the Royal Decree of January 19, 1990 and Royal Decree 5/1996. The legislative framework regulates the methadone-dispensing facilities in the different Autonomous Communities and Autonomous Cities and specifies that, in each one thereof, there shall be a Commission for the accreditation of the centres and services which take care of carrying out these programmes.
"As mentioned in other reports, a growing number of opiate-dependent (especially heroin-dependent) individuals in our country have been progressively joining substitution programmes from 1990."
