Mike Dewine is trying to ban Kratom ... The War on Drugs is how old?

 Yes, while the specific term "war on drugs" was popularized by the media, President Richard Nixon did formally declare drug abuse as the nation's "public enemy number one" on June 17, 1971, marking the start of his administration's intensified efforts against drug use and trafficking. He presented a special message to Congress that day, advocating for more federal resources to combat drug abuse, although the media focus was on the stronger language he used.
