The Ontario Provincial Police are warning that people at risk of self-harm have been receiving packages of a potentially dangerous substance through the mail after being purchased online.
The packages contain sodium nitrite in the form of white crystals. It is commonly used as a food additive, especially in the production of processed meats.
Anyone who intentionally consumes excessive amounts of sodium nitrite will experience reduced oxygen levels, impaired breathing, and could die.
Below is the entire OPP Public Safety Warning.
