Therefore all judicial authorities must consider the lack of malicious intent in the interventions of the Ministry of Health and Medical Education as well as those of other centres and organizations that are active in this field. They must not accuse service providers of assisting in the criminal abuse of narcotics and must not impede the implementation of such needed and beneficial programmes.
