Desomorphine, a Krokodil drug which is also known as "Zombie drug" as it internally bites up one who has been injected. The drug was discovered in the early 1930s and named desomorphine as it is a faster-acting alternative to morphine.
Despite desomorphine originating in the United States, recreational use of krokodil really took off among drug addicts in Russia. Description from rehabcenter.net. I searched for this on bing.com/images
