Health Bill

I understand my hon. Friend’s point and we might not have explored fully all the engineering solutions that might help to reduce exposure to toxins emitted through tobacco smoke. Indeed, the aetiology of the increased risk might not be entirely clear. Rather than the nicotine content, which is what is typically measured, other toxins might get into the system and change metabolic responses. We need to be clear about that. It might be intensely difficult, however, to remove the carcinogenic material from tobacco smoke that affects other people.
