A 35 year old female came to your OPD for smoking cessation. She was diagnosed with depression 2 years ago and took SSRI for 6 months. She is off medication for 1.5 years & now is mentally healthy. She staed smoking at the age of 25 years & she tried quitting on her own using nicotine gums several times but she is unable to sustain abstinence for more than 1 month. What would be the best recommendation in this patient?
