"The announcement of AIADMK and DMK reflects how fast the concept of Bihar going for total prohibition is spreading in other regions," Kumar told reporters after his weekly 'Janata Ke Darbar mein Mukhya Mantri' programme.
Kumar, who declared Bihar a total dry state last week, said states like Jharkhand, Uttar Pradesh and West Bengal, sharing borders with Bihar and who were enjoying a jump in sales of alcohol after prohibition in Bihar, would soon face similar demand against alcohol from their people.
He also trashed pleas of hotel and restaurant owners that the ban has hit their business and would be a big deterrent to people coming to Bihar.
"They mean to say people used to visit them only for boozing?" Kumar asked adding, "Everybody knows that foreign tourists visit Bihar mainly out of respect for Buddhist holy places in the state. Others come to perform 'pind daan' of their ancestors... Will they stop coming to Bihar after the ban on alcohol?"

"You can understand that I ordered the ban on liquor in one stroke of pen without caring loss of revenue of Rs 5,000 crore annually generated out of it," he said.
In reply to a question about media reports on the death of four habitual drunkards so far in de-addiction centres after the ban, Kumar said he lamented such tragedy.
He said the state government would pay compensation to the family in such incidents of loss of life in de-addiction centres.
