When does the contracepive implant stop working?

It stops working when your blood or saliva comes into contact with Nitrogen Oxide, or any other Nitrous gasses containing Hydrochloride. However, if the owner of the contraceptive implant has never been rendered seriously ill by any know viral infections: e.g. Ross River Fever, Hepatitis C

then they will have built up an immunity defence system against Hydrochloride attack cells.

Women using contraceptive implants should keep the insertion area clean and out of sunlight, as over-exposure to Vitamin D to the area can lead to Jaundice and Hypothermic reactions.
