Some New York beer distributors agreed Saturday to stop selling caffeinated alcoholic beverages like Four Loko, the AP reports.

The distrbutors have promised to stop deliveries by Dec. 10.

The news comes after a slew of states across the country have banned or are looking into banning the sale of these drinks.

The Associted Press obtained a statement from the New York Liquor Authority ahead of an expected Sunday announcement.

From the AP:

"We have an obligation to keep products that are potentially hazardous off the shelves, and there is simply not enough research to show that these products are safe," said Dennis Rosen, chairman of the state Liquor Authority, in the statement.

It was not immediately clear which distributors had signed on to the voluntary ban, but the state Beer Wholesalers Association was quoted in the statement as saying it applauded the liquor authority for its "willingness to work with the industry."

The NY Daily News reports:

"And the maker of the sweet-but-potent beverage has agreed to stop shipping its wildly popular drink to New York distributors after Nov. 19. 

The dual agreements will allow the [state Liquor Authority] to fine any shop owners found to be selling Four Loko without proof it was ordered by the deadline, authorities said."

Just last week, following the lead of Michigan, Oklahoma and Utah, Washington became the next state to prohibit vendors from stocking and selling Four Loko.

The unanimous vote came one month after nine underage students at Central Washington University were hospitalized for reportedly becoming "dangerously ill" from drinking "large amounts" of Four Loko at an off-campus party.

The caffeinated alcoholic beverage commonly referred to as a "blackout in a can" is making waves on college campuses where students are "getting Loko" and loving it.

The Pennsylvania Liquor Control Board has discouraged vendors from selling the beverage until the FDA rules on its safety. The Chicago City Council is also reportedly looking into a ban.

More than 20 students have been hospitalized for Four Loko-related incidents at Ramapo College in New Jersey. The school has since banned the drink.

Other schools including Harvard University, Lebanon Valley College in Pennsylvania and the University of Rhode Island are warning students of the dangers of the beverage or prohibiting it on campus.

One 23.5-ounce can of Four Loko is said to contain the equivalent of four or five beers and the caffeine in two cups of coffee.

In its ruling, the Michigan Liquor Control Commission said the drinks "present a threat to the public health and safety" and that "the safety of ingesting a mixture of stimulants and beer, e.g. Alcohol Energy Drinks, has not been established."

Liquor vendors were given 30 days to remove the products from their shelves.

The drink's manufacturer, Phusion Projects Inc., appears to be standing by the product as the Food and Drug Administration reviews its safety.

The drink's 12 percent alcohol content, combined with caffeine and other ingredients, has experts and medical officials worried.

From ABC News: 

"The problem is when you put all these things together, it's a nightmare," Harris Stratyner, vice president of the Caron Center and an addiction specialist, told "Good Morning America." "The caffeine may make you feel like you're not getting drunk as quickly so you may ingest more." 

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.
