Page "Truth drug" Paragraph 5

A defector from the biological weapons department 12 of the KGB " illegals " ( S ) directorate ( presently a part of Russian SVR service ) claimed that a truth drug codenamed SP-117 was highly effective and has been widely used.

According to him, " The ' remedy which loosens the tongue ' has no taste, no smell, no colour, and no immediate side effects.

And, most important, a person has no recollection of having the ' heart-to-heart talk '" and felt afterwards as if they suddenly fell asleep.

Officers of the S directorate used the drug primarily to check the trustworthiness of their own illegal agents who operated overseas, including even heroes of the service, such as Vitaly Yurchenko.

According to Alexander Litvinenko, Russian presidential candidate Ivan Rybkin was drugged with the same substance by FSB agents during his alleged kidnapping.
