Union Home Minister Amit Shah on Wednesday said a "ruthless approach" has to be taken against narcotics traders to eradicate the menace of drugs in the country and asked all state governments to keep aside their political differences and join the battle.

Addressing the first conference of the heads of anti-narcotics task forces of states and Union territories, Shah said the Narendra Modi government has set a target to make the country drug-free when India attains 100th year of independence in 2047.
