It was stated that there is no evidence that plain packaging or any other possible measure would increase illicit trade.
Really?! There is no possible measure that would increase illicit trade? So smuggling and contraband is not affected by supply, demand, price or the ease with which it can be done? That's sounds a little, er, counter-intuitive.
There would probably rather be a decrease.
Sure. If you're going to make things up, you might as well go the full mile. But that is merely the aperitif. This is the good bit:
Generic packaging would make it harder to imitate another company's package as it could only be done by copying the brand name.
