As far as I can tell from Part 1 of the article which is posted, the discussion is more of society's use of Opium through the latter part of the millennia. It doesn't go into any specific purveyor of opium products except for the regulation and subsequent clandestine production after prohibition.
> By Regulation XIII of 1816, opium cultivation was legalised in Bengal under the supervision of the Commercial Resident of Rungpore. The control of the Opium Department went from the Board of Revenue in the Customs, Salt and the Opium Departments by the Regulation IV of 1819. In 1850, by Act XLIV, the Customs, Salt and Opium Board was merged in the Board of Revenue at Calcutta. In 1797, prohibition was imposed on the private cultivation of poppy in Bengal proper and in Behar division of the province. It was then that the attention of the Government proper was being met by ‘systematic smuggling and clandestine production’
I am really curious about the Tata family role in this that you allude to. Please elaborate.
