The city wants a pack of alleged cigarette bootleggers — including a woman with lung cancer — to cough up $6.5 million in unpaid taxes.

In a civil-racketeering suit filed yesterday in Manhattan federal court, alleged Brooklyn megabuyer Roza Budansky and dozens of others are accused of trafficking more than 437,0000 cartons of smokes they bought online or over the phone.

None of the cigarettes was subject to city’s $1.50-a-pack excise tax, court papers say. Budansky allegedly purchased 32,232 cartons of unstamped cigarettes at a cost of $957,306.43 between February 2006 and December 2008.

Budansky, 64, admitted to The Post that she bought some cigarettes for drivers at a Manhattan limo company where she formerly worked, but she disputed the amount alleged in the suit.

She said she stopped working in July 2006 after being diagnosed with lung cancer, suggesting that someone at the company continued placing orders in her name.

“There were, like, 30 people there,” she said. “They were all buying.”
