Homemade drugs have had devastating effects on addicts across Russia, where about 100,000 people are thought to be making and using substances made from legal and easily available ingredients.

One of the drugs, called 'Krokodil' (or crocodile), named after the scaly-looking sores it causes, is made from a combination of headache pills, petrol, paint thinner, hydrochloric acid, iodine and red phosphorous scraped from the strike strips of matchboxes.
