Strumpet, the link between prostituted women and class a drug us is well documented.
^80-95% of women who are involved in street prostitution are problematic drug users. [May, T. and Hunter, G. (2006). Sex work and problem drug use in the UK: the links, problems and possible solutions. In R. Campbell and M. O'Neill (eds.). Sex work now. Cullompton: Willan]
87% of women in street-based prostitution use heroin. [Hester, M. and Westmarland, N. (2004). Tackling Street Prostitution: Towards an Holistic Approach, Home Office Research Study 279, London: Home Office.]
An Australian study of women involved in street-based prostitution found very high rates of drug use (83% heroin, but also cocaine, methamphetamine, cannabis and alcohol) and injecting, as well as risky use behaviours. They also found very high levels of mental health problems (e.g. 54% severe depressive symptoms), including suicidal thoughts (74%) and attempts (42%). [Roxburgh, A., Degenhardt, L., Copeland, J. and Larance, B. (2008). Drug Dependence and Associated Risks Among Female Street-Based Sex Workers in the Greater Sydney Area, Australia. Substance Use & Misuse, 43, 1202-1217.^
Yes, the women in my example have various challenges in their lives, but in my view, one of the major problems that they face is that a particular subset of men think that it is acceptable to exploit their personal difficulties and prior abuse in order to exploit them for sex that they would otherwise not be willing to give them. Criminalising johns makes it clear that this is not defendable or acceptable.
