What is the first step towards quitting smoking?

I am always worried because my husband is a smoker.

In my opinion, smoking seems to be detrimental to health as well.

It's no use nagging a hundred times.

It's no use even if we try to reduce it little by little.

They say it's due to stress, so they are smoking.

How do you really start quitting smoking?

You need to have a sincere will of your own, right?

My family members are always worried because it seems like nothing can be done about it.
