Zyban vs Chantix – Differences

Zyban (active ingredient – bupropion) is a drug prescribed by your healthcare provider to help you stop smoking. It belongs to a class of drugs called antidepressants. For most users, this medication reduces cravings and withdrawal symptoms, like – frustration, irritability, anxiety, anger, restlessness, trouble concentrating, and depression.

Chantix (active ingredient – varenicline) is in a group of drugs called partial cholinergic nicotinic agonists. While it does not contain nicotine, this medication functions by stimulating nicotine receptors in the brain, hence, reducing cravings for smoking cigarettes.

In conclusion, both these medications are used to help people quit smoking, but have different main ingredients. The problem is that they have many side effects. It is better to use your will and other natural methods to quit smoking.

Effective Methods To Help You Quit Smoking

#1 St. John’s Wort

It is mainly used to treat depression, however, according to some research and anecdotal evidence, this medicinal herb may help people quit smoking much easier.

#2 Ginseng

It stops the release of dopamine (the molecule behind all our most secret cravings and sinful behaviors) that is the leading contributor to why people enjoy the act of smoking tobacco. To use it, you may include a tsp of ginseng powder into your breakfast.

#3 Grape Seed Extract

It is made from the ground seeds of red wine grapes and contains a high quantity of proanthocyanidins. According to the data, this supplement helps reduce the damage caused to the lungs due to smoking.

#4 Physical Activity

Your potential to quit smoking tobacco is considerably increased when you practice a daily physical exercise for at least 30 minutes. Also, the exercise should be vigorous enough to hit at about 80% of your max heart rate. Doing this, your body releases chemicals called endorphins (natural opiate-peptide chemicals).
