Alternatively, you could do as we do and smoke electronically. Technically it's not smoking as there is no combustion taking place, what comes out is vapour rather than smoke .
Providing you get a decent one, they're actually excellent. I've quit smoking tobacco altogether about three months ago, after 30 years and numerous failed attempts, and it was so easy I don't even know exactly when I quit !
Of course I'm still addicted, but at least what I'm taking in now is only nicotine, minus all the other nasty stuff, and have also managed to bring down the nicotine use by using cartridges with less nicotine...
Cheers,

NB: for more information: here you can find a NZ website dedicated to Electronic Smoking (which also has a forum, albeit an, as yet, modest one).
Please note that, at this point in time, cartridges containing nicotine cannot be (legally) bought/sold in NZ, but buying them overseas is no problem. PM me if you'd like more information or personal experiences with various brands (I do not sell them or in any way represent any specific company that sells them, just very enthusiastic about this product and what it has done for us).
