Gerin oil

Gerin Oil or Geriniol is a fictional drug used as a device to criticize religion in articles written by Richard Dawkins. It is an anagram of religion.

The first article, Gerin Oil, was published in an American secular humanism publication, Free Inquiry, in December 2003. It was popularised in an article titled Opiate of the masses. It describes a dangerous legal drug "Gerin Oil" or "Geriniol." Dawkins blames its effects as being responsible for historic acts of violence such as the September 11th attacks, massacres of native South Americans by conquistadors, and the Salem Witch Trials.

According to Dawkins, users are often introduced to the drug at social gatherings such as weddings and funerals. In small amounts it is considered harmless, although its usage may increase over time. Medium usage of "Gerin Oil" is said to cause a disconnect with reality where users expect private wishes expressed to come true, often accompanied by spasmodic muscular movement or contraction. In large doses it is said to cause aural or visual hallucinations.

Its use is also linked to child mutilation, sexual prohibition, and the tendency to smile when convicted of mass murder.
