"You can blow over the legal limit on a roadside police breathalyzer just by having a little Scope, Listerine, breath spray-type things in your mouth when you get stopped," company co-founder Ron Lloyd, a former state trooper, says in a YouTube demonstration, adding that the product "doesn't do anything to help someone who is truly intoxicated."

A few squirts of breath spray can bring a breathalyzer reading up to 0.181 percent -- more than double the legal limit of 0.08 percent alcohol, according to Lloyd's video. But Breathalyzer Equalizer powder brings the reading down to 0.021 percent.
