1-Iran Prisons Organisations will be going to extend the programme to the rest of the Iranian prisons in case the results are satisfactory and there are minor complications.2-Voluntary entrance of the prisoners into the PNEP shows that despite the access to the other harm reduction programmes, the need and desire to inject drugs will not disappear and if the prisoners are not given sterile syringes and needles, they will share them. 3-Programming, process, problems and their solutions during the programme can be of great help to the rest of the Iranian prisons and other prisons worldwide. 4-The average number of prisoners who entered the programme in the three target prisons has been between 25 and 35 per month and the volunteer prisoners have always intended to use syringes. 5-The average age of starting the injection has been 25 which simply shows a young majority which can help spread the diseases in the society more rapidly. And almost half of the mentioned prisoners are married and will act as a bridge to spread the disease in the society in a faster pace. 6-The other demographic characteristics of this group of IDU's including education, profession, etc. should be considered in harm reduction programmes planning. 7-The high frequency of drug-related crimes shows the necessity and importance of considering these prisoners in harm reduction programmes. 8-As mentions by the IDU's, they inject drugs three times a day and this figure can help in determining the number of needed syringes during syringe distribution. 9-A high proportion of prisoners have no laboratory records of HIV, HCV and HBV while this is the most high risk group and access to consulting services and laboratory tests must be made available for them. 10-The high proportion of prisoners with multiple partners has made this group very special in harm reduction programmes and if not properly controlled, they can be infected by HIV easily and the virus is then spread among the partners and later to the society. Syringe distribution among these prisoners can help reduce the problem.
