Naswār (Pashto: نسوار; Cyrillic script: насва́р), also called nās (ناس; на́с), nāts (ناڅ; на́ц), or nasvay (نسوای; насвай), is a moist, powdered tobacco snuff consumed mostly in Afghanistan, Pakistan, India, Iran, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, and Uzbekistan. Naswar is stuffed in the floor of the mouth under the lower lip, or inside the cheek, for extended periods of time. It is similar to dipping tobacco and snus.
Naswar was introduced into Western Europe by a Spanish monk named Ramon Pane after Columbus' second voyage to the Americas during 1493-1496. In 1561, Jean Nicot, the French ambassador in Lisbon, Portugal, sent naswar to Catherine de' Medici to treat her son's persistent migraines.
The green powder form is used most frequently. It is made by pouring water into a cement-line cavity, to which Lime (calcium hydroxide) or juniper is added as flavorings, and then air-cured, sun-dried, powdered tobacco is added. Indigo is added to the mixture to impart color.
Currently, the countries of the region freely sell naswar in the markets, usually on trays with cigarettes and sunflower seeds. The only exception is Turkmenistan, where in 2008 President Gurbanguly Berdimuhamedow signed a decree banning the production, sale, use, and import of naswar.
