Bhang, as many backpackers slouching through South Asia would know, is a degraded form of cannabis, commonly known as hash. In parts of India, balls of bhang can be purchased at government dispensaries — after all, the drug has a long history of use in the country, tied to certain ecstactic rituals of both Muslims and Hindus in the subcontinent.
