The reason I am inquiring this is because I knew of Netherlands having the lowest rate of HIV/AIDS and they justify it by their Liberal approach to the social ills: legal prostitution, legal heroin with lowest addiction rate in Europe, granted, they are using cannabis and again, the argument is being made that they are not using hard drugs (hence not injecting it) and claiming to have broken the connection between soft and hard drugs. Also, the lowest rate of prison per capita hence no irresponsible sexual behavior.
Do you have url (website) to show me that data, pls?
