cannabis is still popular in India as bhang
Bhang is mixed in thandai, a milkshake-like preparation. Bhang is consumed as prasad of Lord Shiva, and mostly it is consumed on popular festivals i.e. Mahashivaratri and Holi. although police might fine two people for smoking tobacco in public places, under the Cigarettes and Other Tobacco Products Act.
Among Sikh Nihangs, bhang is popular, especially during Hola Mohalla.
Indian Sufis place the spirit of Khidr within the cannabis plant, and consume bhang.
In Odisha, cannabis consumption is legal, and it is common to see people smoking chillums(home-made Cigarettes).
but I think it should be banned here in India except for medical benefits because youths are getting addicted to it.
