What is a common indicator of effective smoking cessation treatment with varenicline?

The indication that a client is no longer smoking is a strong indicator of effective smoking cessation treatment with varenicline. Varenicline works by targeting nicotine receptors in the brain to reduce cravings for nicotine and withdrawal symptoms. A significant outcome of this treatment is the cessation of smoking itself, which demonstrates that the medication is fulfilling its intended purpose. When a client is able to stop smoking, it indicates not only the effectiveness of the medication but also an overall positive response to the smoking cessation program. Other factors such as cravings or changes in weight may relate to the treatment but do not directly measure its success in terms of smoking cessation.
