A bit culture today. Naswar is moist, crushed tobacco leaves and is used as a snuff. It is popular in Afghanistan, Pakistan and Iran etc. In Pakistan, it is used by Pathans (people of North West, along Pakistan/Afghanistan/Iran border) and sold by Pathans.
People put a pinch inside the mouth where it gets mixed with saliva. Quite harmful for oral hygiene. The spit is also messy and dirty. I am a smoker and understand addiction of nicotine. But Naswar is probably the messiest way of getting nicotine dose.
But then this is culture. How can I object?
