The clinical trial will be held at the Tommy G. Thompson Youth Center at Wisconsin State Fair Park, WISN 12 News reported.
According to Smoke-Break inventor Brett Roth, liquid nicotine is a colorless, cherry tasting gel spiked with nicotine.
Roth, who just received a government go signal to begin testing, claims it broke his cigarette habit after two decades of smoking.
"For 20 years, I was getting toxic smoke, so I was used to some sort of a kick, and I liked that. So even though it's cherry flavored and it's very sweet, it does have a kick, and it felt like I was still smoking," Roth was quoted by WISN.
"It's less than two calories each, fat free and about one-third of a carbohydrate," said Roth who is collaborating with retired cancer specialist Dr. Nicholas Geimer.
