One liquor store owner warns it can be deadly.
James Dobreski says most of his business here at The Liquor Store comes from Binghamton University.
He does not sell grain alcohol which is illegal in New York.
Grain is almost pure alcohol, and more than twice as strong as common hard liquors like rum or vodka.
"It's lethal, I mean literally it's lethal. Even mixed with something it's going to be lethal, that's obviously why it's been banned, people get sick and can die," says Dobreski.
Several B-U students were recently treated at local hospitals, after drinking grain alcohol off campus.
BU says grain alcohol can be dangerous and often mixed in with other alcoholic drinks.
It's not sure how many students got sick, and university police are still investigating.
