Most of the people whp smoke do it for enjoyment sir, and the addiction to smoking is developed by chance. You keep enjoying one puff ost day then two puffs and one day you smoke a full stick jus for fun however you never know when it will be the permanent part of you life.
You dont have to quit once for all you jus have to tapper it if you are a chainsmoker. Nothing is difficult sir you can do it. Please do it now is the best time.
There are other alternatives use them but quit smoking it errodes your health..
Hope yoi will do the best towards positivity. Thank you sir @jerrybanfield
