Addiction

 One who can't live 

without alcohol,

Without drug,

Without tobacco,

Doesn't mean addiction.

It is also about 

One who can't live without makeup,

One who is a foodie,

Can't live without a person,

And so on....

Addiction includes everything else which you can't live without

Everything was a part of life though 

Make a move without these for a day, 

And that makes you realise what you are addicted too...
