Lord Kamall (Con)

My Lords, my noble friend has tabled a number of amendments on heated tobacco products. Although there may be some concern about what is behind them, they raise important questions that I am afraid the Government have yet to answer with any real precision. As I noted in Committee, there appears to be some evidence that individuals who switched from conventional cigarettes to heated tobacco products show lower levels of exposure to harmful chemicals than those who continue smoking. I am just comparing them to cigarettes, not to vapes. To be clear, I do not suggest that this settles the question of harm—these are relatively new products, and the long-term evidence base is still developing—but it means that the Government cannot simply treat heated tobacco products as interchangeable with conventional cigarettes without explaining why they refuse to consider their relative harm compared to cigarettes. I am talking about not absolute harm, but relative harm. There is also the practical question of where these products may be used. The position on indoor and outdoor spaces remains, as far as I can tell, unclear. Heated tobacco does not produce combustion or sidestream smoke in the conventional sense, and yet it is not obvious from the Bill how the Government intend to address that distinction—if they intend to address it at all. More fundamentally, can the Minister explain what specific evidence underpins the decision to include heated tobacco in the generational ban? I am sure all noble Lords accept that current evidence shows that vapes are relatively safer than smoking. It may be that vapes are relatively safer than heated tobacco, but as yet, we have not seen definitive evidence. Unfortunately, as noble Lords have said, much of the research on heated tobacco is funded by the tobacco industry. I can understand the concern there. I hope the Minister will correct me if I am wrong, but there is no definitive independent research on the relative harms of heated tobacco. If there is definitive research, can the Minister write to noble Lords with links to the relevant academic papers? I think we saw one link to a meta study that was not very good, but there has been no meaningful in-depth research. This reminds me of a conversation I had with a friend, who told me that when they tried vapes to quit smoking, it unfortunately did not do the job for them. When they went back to their doctor, he said that he was not supposed to do this, but he suggested heated tobacco as a relatively less harmful alternative. While he hoped his patient might have switched from cigarettes to vapes, since this had not happened—we do not live in a perfect world—he preferred his patient to use heated tobacco to going back to cigarettes. Once again, this was a practical approach based on relative harms. I completely understand the concern that, if we overpromote heated tobacco, we might find that smokers switch to it rather than vapes. Given that the policy rationale rests substantially on reducing harm—we should be looking at absolute harm and relative harm— I would welcome clarity on whether the Government are satisfied that the case for treating heated tobacco like cigarettes is proven. It will be interesting to see that distinction between heated tobacco and cigarettes. Is the science still sufficiently uncertain to warrant a more cautious approach?
