Cutaneous Foreign Body Granulomas

"Lumps" of scar tissue which form around foreign bodies under the skin or elsewhere in the body.

These are benign growths of scar tissue that are associated with subcutaneous injecting or missed hits, where the solution has ended up in the surrounding tissue. This residue may stay for many years eventually leading to this condition. Many of the ingredients used for cutting are not thought to cause this but the injection of crushed tablets will increase the risk. Successful intravenous injection of crushed tablets does not reduce the risk of granuloma formation. It just changes the place in which they are found to the lungs.

The best harm reduction advice in this case is not to inject crushed tablets.
