Narcs, or narcotics officers, target pushers (6 letters), WEED (4 letters), and perps (4 letters). Pushers are people who sell illegal drugs, such as marijuana, cocaine, and heroin. WEED is a slang term for marijuana, which is an illegal drug. PERP is short for perpetrator, which is someone who has committed a crime. Therefore, narcs target people who sell illegal drugs and those who have committed crimes related to drugs.
