My Grandmom used to smoke when i was kid, and I know many Old Ladies who used to smoke!! I doubt it's a western infuence, smoking (be it hukka, bidi or churot) is in our culture!! (remember Shiva??)

I feel its western who got influenced by us, during 70s lots of Westerners used to come to Nepal for Hasish Cafe (Legal then), even today we are doing good in Trance Parties :P
