One fact is undeniable — prohibition has led to a significant revenue loss for Bihar. The Comptroller and Auditor General of India (CAG), in a report published in 2018, stated that the state’s revenue dropped by ₹1,490 crore in 2016–17, primarily due to the liquor ban. Meanwhile, spending by the state excise department nearly doubled that year, from ₹49 crore in 2015–16 to ₹91 crore, owing to the costs of enforcing the policy.
Direct investment also took a hit. During his first term as chief minister in 2005, Kumar had promised to liberalise liquor trade to boost revenue. The result was an eightfold increase in excise receipts, from ₹500 crore to ₹4,000 crore. UK industrialist and Cobra beer owner Karan Bilimoria established a distillery in Bihta and announced plans, in partnership with international beer brand Molson Coors, to set up 10 more units in Bihar, supporting barley production in the state. But after 2016, according to sources close to him quoted in Business Standard, the state government would not even permit him to repurpose the Bihta facility to produce fruit juice.
