Drug-related debt and exploitation are fundamental drivers of violence, coercion and systemic instability within the prison estate. The prevalence of drugs creates a shadow economy where debts, which can accrue up to £10,000, are collected through intimidation and violence. The consequences extend beyond the prison walls, with criminal networks coercing family members to pay a prisoner’s debt, sometimes through sexual favours, smuggling or cuckooing. Furthermore, those in debt are routinely exploited, being forced to test new drugs, hold weapons, assault staff, and undermine security. (Conclusion, Paragraph 54)
