A rather silly, illogical post Nuttsie but just as a response regarding tobacco I think Australian tobacco probably does more harm than some overseas leaf because there are more chemicals in it here. Friends who smoke tell me that cigarettes sold here also burn a lot faster than some overseas ones so you need to light up more of them and this is apparently due to saltpetre being added to cause just that. A marketing ploy I suppose as the faster they burn the more you can sell. Dave R.
