By the sixteenth century, in India, opium was more than a mere herbal medicine or a valuable item of maritime trade. From its earliest introduction around the tenth century AD, to its wide and swift diffusion by the fifteenth-sixteenth centuries, the assimilation and the subsequent ‘Indianisation’ of opium proved to be a major cultural watershed, particularly in Bengal, Behar, North-Western Frontier provinces, Central India, and certain parts of Rajputana. Here, opium attained the status of connoisseurship, like that in China, where the thakurs of Rajputana, the rajas of Punjab, the kathis of Kathaiawar and the Mughals padshahs, perfected and refined opium eating into an art and craft.
