Prior to injection, drugs in powder, solid and tablet form must be mixed with sterile water and possibly an acidifier (depending on the drug) and broken down into a liquid solution. Cookers are the containers used for this drug preparation process, often heated to create a desired drug consistency. Cookers do not contain harmful products or chemicals so the user will not be harmed when the product is heated. If reused, this piece of equipment can be a transmitter of blood-borne viruses, HCV and HIV. Therefore, it is important to remind clients that just like needles, cookers are for single use only.
There are two types of cookers provided through OHRDP: the stainless steel Spoon and coloured Stericups, which contain a filter and a dry swab. Both types of cookers are sterile and a much safer container to mix drugs in than tablespoons, cans, or bottle caps, as they heat more evenly and are not contaminated with the bacteria as other household items may be.
