Same old story !! It's simple,like drug-addiction ; legalise it, and then you can REGULATE it .....cut out the pimps,people-traffickers,procurers, etc, and allow those women who WANT to follow that path,for whatever reason,to do so in safe,sanitary,licensed premises which are regularly inspected by Medical Officers.Some other,more enlightened, countries have,I believe, done something along similar lines with marked success.
