By 1972, the BNDD is 1,361 agents strong.

February 4, 2003: The New York Times publishes an editorial defending Ed Rosenthal and medical marijuana. It says, in part: "The Bush administration's war on medical marijuana is not only misguided but mean-spirited. Doctors have long recognized marijuana's value in reducing pain and aiding in the treatment of cancer and AIDS, among other diseases. A recent poll found that 80 percent of Americans support legalized medical marijuana. The reasons the government gives for objecting to it do not outweigh the good it does. And given the lack of success of the war on drugs in recent years, there must be better places to direct law enforcement resources."

Four months later US District Court Judge Paul Friedman rules that Istook's law violates the First Amendment by infringing on free speech rights, and is thus unconstitutional.
