Smoking is the most deadly addiction. A smoker will usually go for many years without ever realizing that cigarettes are killing him.

Damage caused by smoking

It is hard to imagine how a person could become addicted to nicotine, but this is exactly what happens when someone smokes. 

Nicotine is an extremely powerful stimulant that acts on the brain and nervous systems like cocaine or amphetamines. 

It is a drug that causes very strong feelings of pleasure, which makes it easy to get hooked on smoking.

If you want to quit smoking, there are several options available:

This type of therapy helps people quit smoking by reducing their cravings for cigarettes while they continue taking NRT during their quit attempt. 

As time goes by, they will find it easier and easier to avoid reaching for a cigarette whenever they feel stressed or bored, until eventually, they have no cravings at all! NRT can be used with or without prescription drugs such as Zyban or Champix (varenicline).

How can I cure smoking addiction?

Smoking is a very addictive habit. It has many negative effects on your health and leads to other medical symptoms. 

There are some people who start smoking at a young age, while others start later. The main reason behind this addiction is the nicotine in cigarettes.

There are several methods to cure smoking addiction:

1) The first method is quitting smoking immediately after you inhale smoke from the first cigarette. 

This is called as cold turkey method and it is extremely difficult to do this because you will feel like you have just lost your best friend when you quit smoking suddenly without any preparation for it.

2) If you are having difficulty quitting smoking, then try to use medications such as NRT (Nicotine Replacement Therapy).
