In Australia a pack of 20 will cost you over 40 dollars. The strategy to reduce smoking by increasing taxes is backfiring spectacularly. Organised crime are making billions out of cheap smokes being smuggled in to the country. Many cheap smoke shops are being fire bombed in gang warfare activities. Nobody has learnt anything from the USA alcohol prohibition in the early part of last century. That was a direct cause of the rise in organised crime. If somebody wants something, someone will supply.
I can buy a pack of 20 for ten dollars at a cheap smoke shop. The government is losing billions in unpaid taxes.
