Stratyner said he saw no reason for caffeine to be added, "other than to give kids an added boost and to get them to purchase more."
"Quite frankly, I think adults that are legal shouldn't drink it either," he said.
In its statement to ABC News, Phusion Projects said Four Loko was as safe as any other alcoholic beverage. "Consuming caffeine and alcohol together has been done safely for years," the statement read. "Our products contain less alcohol than an average rum and cola, less alcohol and caffeine than an average Red Bull and vodka, and are comparable to having coffee after a meal with a couple glasses of wine."
Central Washington University announced at a news conference in Ellensburg, Wash., that more than 50 students had become ill at the party and that the blood-alcohol content of students ranged from .12 percent to .335 percent.
In Washington, 0.08 is the legal limit for intoxication, and 0.3 can be lethal.
Washington State Attorney General Rob McKenna said he would ask the FDA to ban the drinks nationwide. Police called to the scene of the house party, in Rosyln, Wash., about 30 miles from the university, found young people -- many of them women -- passed out throughout the house and on the front lawn.
Police were suspected immediately that drugs were involved, but interviews with the students and toxicology tests ruled out drugs, police said.
"Perhaps even more disturbing," said Police Chief Steve Rittereiser, was that students were drinking beer and vodka in addition to Four Loko.
Attorneys general in New York and New Jersey have also called for federal investigations following incidents involving college students in those states.
"There's no redeeming social purpose to be served by having the beverage," Ramapo College President Peter Mercer told The Associated Press after he banned the drink on his campus when several students became sick.
