The area that I have the biggest concern about is the low-nicotine cigarettes, and it does worry me that we may be doing more harm than good and I encourage the select committee to really drill into this. Why do I say that? Well, as Brooke van Velden has mentioned, nicotine is the addictive substance, but it's the other things in smoked tobacco that causes the harm. Nicotine itself just really doesn't do much harm at all, except hook you into the substance. It's the toxins, the tars, and the carcinogens that are in smoked tobacco that cause all the harm. So the policy question, therefore, is this: if nicotine levels drop, will people compensate—what's known as compensatory smoking? Will they smoke more?
