"Voting for Congress candidate Ravi Naik means saying yes to drugs. So, it is right time for the people to say no to drugs," BJP Goa spokesman Dr Wilfred Mesquita told PTI.
Naik, who is contesting on Congress ticket for the North Goa Lok Sabha seat, was last year indicted in a state Assembly Committee report along with his son Roy, for their alleged links with the drug syndicate in Goa.
The North district, a hub for tourism spots like Calangute, Anjuna, Morjim, has witnessed drug menace.
The CBI had summoned Roy Naik for probe last year.
Goa Congress unit chief John Fernandes had earlier this week said that the allegations of drug nexus were discussed with the party's central election committee and it had given a clean chit to Naik.
