"Although in Russia drug use per se is not criminalized as in Georgia, possession without intent to supply in amounts exceeding 0.5 grams for heroin, opium or desomorphine is considered a crime and is punished by incarceration for up to three years27. At the same time it is important to emphasize that even where drug use is not a criminal offence, most countries apply administrative liability for it; in Russia, drug use can therefore result in 15 days arrest, which according to the European Court on Human Rights is equal to criminal liability."
