are potentially serious in infants and can include rickets (in children), fits, heart problems or even death in extreme cases. People who have been kept in captivity for a period of months or more, especially pregnant women, young babies, and growing children should be considered for testing of vitamin D levels and for provision of vitamin D supplements. Some victims of trafficking who have been confined for long periods of time may prolong these conditions after their escape because of their psychological fear of venturing outside. HBF clinicians also observe injuries from exploitative labour which are due to hazardous environmental conditions and a lack of basic training and safety equipment, for example injuries from chemicals, including acid and cookingrelated burns. A detailed history of all of the aspects of trafficking is required in order to document the clinical impact upon each person. A South East Asian man trafficked for exploitation in cannabis production “They took me to the house where the cannabis was growing. The trafficker warned me that if I left the building, he would not be responsible for my safety and he could not guarantee that the posted security guards would not kill me. The door to the premises was locked and I did not have a key. The windows were covered. There were other people already in the building. None of them had a key to the door. “There were no beds, mattresses or blankets. I had to sleep in a room with one other person. The space was very cold but the areas where the cannabis was growing were very hot. The only food we had to eat was rice and sauce. There was a toilet, but no shower. We had to boil water in order to wash. There was soap and shampoo but no towels. I dried myself with my own clothes. I felt scared about being locked in the building. I felt imprisoned. “I did not expect to find myself locked inside a cannabis factory. I thought I would be working in a shop or in some other normal job.” 65
