this, most people who smoke travel they bring back cartons of luckies, camels and marlboros and sell some to friends. all of our cigarettes are virginia tobacco as far as i know and not everyone likes them. they also have the new r.i.p./f.s.c. paper which tastes pretty bad, if you can get normal cigarettes without that then you can probably make some good money. honestly, even really crappy mexican brands taste better than anything you can get at a gas station here.
another thing is most provinces add $6-$7 dollars in tax per pack, if you can get around that selling on the internet then even better.
