Sin Taxes, is it good or bad?

[Kakashi2020]

In my country the amount of Sin Tax or taxes levied on "unhealthy products" like alcoholic and sweet beverages, tobacco and even chips and what they consider as junk food increase exponentially in the past year. The effect of the increase can be seen on supermarkets where a bottle or can of soda has almost doubled it's price. Cigarettes which costs only $0.50 per pack is now $1.50.

I'm a casual drinker and I smoke half a pack of menthols a day. I drink sodas and powder juices and I snack on chips, I do really think that Sin Tax for all the good it may do is not justifiable.
