General Raheel visited the headquarters of army- controlled Anti-Narcotic Force (ANF) in Rawalpindi.
He was given a briefing by Director General ANF Major General Khawar Hanif about the force's counter-drug smuggling operations, military spokesman Major General Asim Saleem Bajwa said.
General Raheel said drug peddlers and those involved in its production are a threat to the national security as terrorists use drug money for militancy.
"We will break the nexus between drug dealers, financiers and perpetrators of terrorism," he said, adding: "We will not allow these drug barons to negatively influence and spoil our future generations."
The Chief of the Army Staff (COAS) also laid a floral wreath at the monument of soldiers who died in clashes with drug pushers.
