There are no laws anymore. Once the tobacco buyout took place all restrictions on tobacco were lifted. You can grow as much tobacco as you want. You can also sell unprocessed leaf. If you are in Canada you can only sell within your Province. You could call some local Gov't Ag agencies but they will be a little annoyed at you. If I get time, maybe later in the week I'll dig up the regs and post them... but don't hold your breath.
