Bloodeaters (1980)

Synopsis
George A. Romero completists will note the presence of Martin's anemic vampire-boy John Amplas in the role of baby-faced federal agent Phillips in this Pennsylvania-lensed horror flick. One of many dead-headed stepchildren of Night of the Living Dead (1968), this film's basic premise is actually more reminiscent of Romero's Code Name: Trixie (aka The Crazies). Said plot involves a band of happy pot-growers whose crops of juju-weed are sprayed by a special new government-approved defoliant called "Dromax" -- which harshes the dopers' buzz so badly that they make the transition from cannabis farmers to cannibal farmers at the drop of a bong. When the inevitable case of the munchies ensues, the hemped-up zombie yokels seek sustenance at the jugulars of anyone unfortunate enough to wander onto their illicit plantation, resulting in gouts of fake-looking gore. Released on video under the more environmentally-aware title Toxic Zombies. ~ Cavett Binion, All Movie Guide
