Why do smokers struggle to complete their Nicotine Replacement Therapy?

Smokers often struggle to complete their Nicotine Replacement Therapy (NRT) due to several factors, including cravings for cigarettes, psychological dependence on smoking, and withdrawal symptoms. Additionally, some may underestimate the length of time needed for effective treatment or experience side effects from the NRT products. The lack of a strong support system and insufficient motivation to quit can also hinder their adherence to the therapy. Overall, the complex interplay of physical and psychological factors makes it challenging for many smokers to successfully complete NRT.
