2 What the industry knew (how to reduce cyanide in its products), when they knew it (1965) and what they did about it (nothing) Charcoal, as in WW2 gas masks, absorbs toxic gases. 45 years ago BAT cigarette company scientists reported that charcoal can reduce toxic aldehydes and hydrogen cyanide emissions in cigarette smoke by 75%-80%. Hydogen cyanide is still found in regular quantities in (the smoke of) all BAT cigarettes tested. Charcoal is not found in BAT or other cigarette filters in NZ, except for Japan Tobacco’s Mild Seven brand. ______________________________________________________________ Murray Laugesen, Jefferson Fowles.

6 Policies are needed to reduce exposure of current and future smokers to the highly addictive tobacco products currently sold The under-18s law does not prevent young people taking up smoking. They obtain instead from older siblings, friends.* The law is not protecting the younger generation. Banning sales to adults will protect the young. Meantime, nicotine in cigarettes is excessive** and needs to be lowered (by nicotine tax, or by sinking lid on all brands). ______________________________________ *Laugesen & Scragg ASH surveys NZMedJ. **Laugesen, Blakely et al.
