Snus, derived from tobacco, is a moist powdered nicotine product combined with various flavoring agents such as citrus and herbs. It is placed in the mouth and absorbed through the gums, delivering nicotine quickly to the brain. While it is sometimes used under medical guidance as a cessation aid for smoking addiction, prolonged use carries significant health risks, including oral sores and increased cancer risks.
From an Islamic perspective, using snus for medical purposes under professional supervision can be permissible as a necessity (zarurat). However, outside such circumstances, its usage is deemed impermissible (haram) due to its addictive properties and harmful effects on health, similar to the ruling on smoking.
