According to the World Health Organization, there is not enough evidence to support that laser therapy can improve quit rates and increase quit attempt success.
To prevent relapse, you will also need to avoid using unapproved therapies. Many communities offer common, alternative therapies such as e-cigarettes, acupuncture, laser treatment, and other alternative measures. These alternative therapies hold claims to aiding in quit attempts but there is no or not enough evidence to support that they can improve quit rate and increase quit attempt success.
If you still need a way to fight the cravings, the W.H.O. recommends using nicotine chewing gums and transdermal patches.
