A tiny amendment buried in the federal transportation bill to be signed today by President Barack Obama will put operators of roll-your-own cigarette operations in Las Vegas and nationwide out of business at midnight.

Robert Weissen, with his brothers and other partners, own nine Sin City Cigarette Factory locations in Southern Nevada, including six in Las Vegas, and one in Hawaii. He said when the bill is signed their only choice is to turn off their 20 RYO Filling Station machines and lay off more than 40 employees.

"We'll stay open for about another week to sell tubes and tobacco just to get through our inventory, but without the use of the RYO machines, we won't be staying open," he said.

The machines are used by customers who buy loose tobacco and paper tubes from the shop and then turn out a carton of finished cigarettes in as little as 10 minutes, often varying the blend to suit their taste. Savings are substantial - at $23 per carton, half the cost of a name-brand smoke - in part because loose tobacco is taxed at a lower rate.

Faced with regulation costs that could run to hundreds of thousands of dollars, RYO machine owners nationwide are shutting down more than 1,000 of the $36,000 machines.

"I feel it's kind of shaky,'' Wiessen said. "The man who pushed for this bill is Sen. (Max) Baucus from Montana, and he received donations from Altria, a parent company of Philip Morris. Interestingly enough, there are also no RYO machines in the state of Montana. It really makes me question the morals and values of our elected speakers."

This appears to be a big dog seeing little bits of profit slipping away from them, and the big dog decided to put it's money behind a bill to stop it.
