No, snus is not classified as a drug.  People may think that snus a drug due to its nicotine content. Nicotine acts on the brain's reward system, leading to feelings of pleasure and can even result in feelings of dependency. However, it's important to note that snus is legally marketed as a tobacco product in many countries, including Sweden, where it is widely used. While snus contains nicotine and can be addictive, it is not classified as a drug in the traditional sense but rather as a tobacco product (but is not legal in the EU, apart from in Sweden). The same goes for tobacco-free snus.
