The 30-minute treatment at her clinics, which costs $450, promises to release endorphins into the smoker's bloodstream to mimic the high felt from smoking and comes with claims of a 90 per cent success rate, far higher than the 12 per cent success rate linked to nicotine patches.
"Scientists may want scientific evidence but I have anecdotal evidence. I make no guarantees but I have had many people who were heavy smokers one minute and non-smokers an hour later."
A professor of public health at the University of Sydney, Simon Chapman, said that Ms Mavety's claims of success indicated she clearly lacked any understanding of nicotine addiction.
"In the history of tobacco advertising there have been a long line of snake-oil merchants, and this has all the hallmarks of being the latest kid on the block," he said.
"There is not a skerrick of evidence in peer reviewed literature to indicate this is anything more than taking money from gullible, desperate people. This would be laughable if it were not so tragic."
Ms Mavety said: "I have never said the laser therapy is a miracle cure. A person has to want to quit, but I have plenty of clients who can back me up."
Ms Mavety, who says she takes about 200 appointments a week, said her treatment included free telephone follow-up care involving dietary tips and psychological advice, a service Professor Chapman dismissed as unscrupulous.
"Nicotine is an addiction in the brain. It is not cured by someone waving their hands over you and saying 'give me the money' or someone, who is not a trained counsellor, telling you to drink cranberry juice."
