Crocodile - Ukraine's new drug threat

The United Nations says extraordinary progress has been made fighting AIDS over the past decade.

But in Ukraine cases of HIV infection have been rising dramatically.

The injection by syringe of a home-made lethal cocktail known as 'crocodile' has been blamed for the spread. It is based on popular eye-drops that can be bought without prescription.

The effects of 'crocodile' are extremely disturbing. Its name comes from the effect it has on skin, making it resemble a reptile. In extreme cases, it can even reduce flesh to the bone.
