>It is often claimed that cigarettes have hundreds of addatives. Are these chemicals actually added to the product in manufacturing, or is the number derrived from it chemical change of organic matter (C,H, and O recombining in every permutation?)

Chemicals are added to products during manufacturing to improve the flavor, make smoking less harsh, and help the cigarette burn slowly and not go out, among many other reasons. Additional chemicals are produced when cigarettes, including these added chemicals, are burned.

Nicotine salts are less harsh to vape than freebase (traditional) e-liquid. Manufacturers developed these products to increase nicotine concentrations while still making e-cigs enjoyable to use. Freebase e-liquids usually topped out at 24 mg/mL while most nicotine salt e-liquids are 50 mg/mL. Nicotine salts aren’t safer than freebase e-liquid.

E-cigarettes may help assist with quitting for adults who are struggling to quit.

New Zealand’s ban aims to protect minors from becoming cigarette smokers while still giving dependent adult smokers access to products that can reduce harm or help them quit.

>I've been using 2mg nicotine gum for several years after quitting tobacco products. I haven't noticed any long term effects. If my dosage stays low, are there any long term issues I may experience?

Congratulations on staying quit! By stopping smoking you have significantly reduced your likelihood of long-term harm. There is little and inconsistent evidence for long-term harm from low doses of nicotine from gum in adults. Nicotine - including nicotine from gum - can be harmful for the developing brain, which includes young and pregnant people.

>Hello everyone! Thank you for having this AMA. I have a question about strategies on quitting smoking for a family member who has been smoking for 40+ years and has tried quitting countless times, but is unsuccessful. He's unsure about using e-cigarettes and nicotine replacement products. What would you recommend to do?

It’s great that you are thinking about this and how to support your family member. The “gold-standard” treatment for quitting is nicotine replacement products or a prescription for Varenicline. This doesn’t work for everyone and often takes many attempts, but tends to get easier each time someone tries. E-cigarettes are a safer alternative to cigarette smoking, especially for people who have a hard time quitting. E-cigarettes have only been around since 2007 so we are still learning about what their long term effects are. Current research supports harm reduction.
