Krokodil 

A heroin substitute that has recently become an epidemic in Russia. Its popularity is thought to be due to the price; up to ten times cheaper than heroin itself and possible to concoct at home. The recipe is readily available on the internet and is cooked up in the kitchens of users before being injected into the arm, groin etc. The high lasts for a much shorter time than most of its opiate cousins; about two hours maximum. This means the user spends most of their day cooking and hardly ever sleeps as a new hit is needed so often. The injection sites become green and scaly, giving the drug its nickname of "crocodile" (or "krokodil" in Russian). Ingredients include over the counter codeine, paint-thinner and match heads. It is the impurities from these that cause the awful side effects which include severe and fast acting gangrene, haemorrhaging, rupture of arteries (often in the heart itself) and widespread necrosis or rotting of the flesh. It is considered to be one of the most addictive and dangerous opiates out there, killing most of its users within one year. Unlike heroin, krokodil causes withdrawal symptoms so severe that a user going cold turkey must be given powerful tranquillisers to prevent them passing out from the pain. This makes coming off the drug so unappealing that addicts will often watch their skin rot away from the bones rather than face sobriety.

Krokodil 

A cheap heroin knockoff that can be synthesized with codeine based OTC pain medicine and cheap, widely available chemicals. The price of krokodil is approximately 10% of street heroin. It is a very popular drug in Russia, where heroin use is the highest in the world, primarily due to Russia's close proximity to Afghanistan.

The drug is extremely dangerous, causing sores and other dermatological issues. The drug breaks down skin and muscle fibers at an astounding rate. The life expectancy of a heavy user is approximately 2-3 years from when the habit begins.

Tim: Check this stuff out, it's "krokodil." It's so cheap compared to heroin and it gives a great buzz! I've been using it for about a month.

Chris: What are those sores all over the back of your neck?

Tim: Beats me, maybe it's the weather?

Kropotkin 

A leading anarchist theorist in the nineteenth century, author of classics such as "Mutual Aid", "Factories, Fields and Workshops" and "The State: Its Historic Role". Most of his works are out of copyright and are available online at the Anarchy Archives at dward.pitzer.au.

Kropotkin was an anthropologist by profession, and this is shown by frequent references to this science in his work. "Mutual Aid" is in large part an attempt to rebut Darwinist arguments for the necessity of individualist egoistic action by demonstrating that mutually supportive, cooperative and altruistic actions are common among animals and in human societies. Kropotkin seemed to think that cooperation is part of human nature, so pervasive it is across different cultures and so resilient it is to attacks by the state.

He viewed the state as a force of atomisation because of its tendency to persecute specific associations. He saw it operating in an imperialistic way, colonising everyday life from above and outside and counterposing itself to the force of society and sociability as an everyday factor. The state is based on violence and control, and hierarchic forms and unnatural and oppressive. The state should therefore be overthrown or overcome, and replaced with social relations based on mutual voluntary cooperation in a series of federated associations.

His thought is best located within anarcho-communism. Although dated in some respects, it still holds up as a critique of sociobiology and of theories of the necessity of state power.

I don't know how it could come to mean "a stupid person" - I assume this is a Slavophobe appropriation of this rather amusing-sounding Russian name.

Kropotkin's Mutual Aid is a classic text of anarchist theory.

Anti-capitalist groups often unknowingly adopt a model of organisation similar to Kropotkin's, favouring small-scale voluntary groups which come together into larger federations for purposes of mutual support.

Krokodil 

So called Desomorphine or cheap heroine.

Illicitly produced krokodil is typically far from pure and often contains large amounts of toxic substances and contaminants as a result of being "cooked" and used without any significant effort to remove the byproducts and leftovers from synthesis. Injecting any such mixture can cause serious damage to the skin, blood vessels, bone and muscles, sometimes requiring limb amputation in long-term users.
Who use krokodil is 99% deadman.
