There have been many studies and surveys about people addicted to drugs/alcohol. And it found that almost all of them had emotional problems or other problems in their lives. They were not happy and not comfortable, so they used drugs to try to become comfortable. And they would use drugs to try to become comfortable every day, because every day they were not comfortable.
And it only becomes worse over time because the actual root problem that causes the discomfort is never looked at and never fixed. And the actual problem is only becoming worse by being ignored.
If you are not happy, then think about why and think about what you can do to make your life better. The power meditations even just the basic ones are enormously helpful in improving the health of a person's soul and emotions. Somebody just made a topic saying the meditations removed all of his depression without even trying just by the increase of energy in his soul.
If you are happy and comfortable, you will not care about cigarettes anymore and it will be easy to quit.
