I believe Nicotine (like Caffeine) is an addictive drug that is absorbed either by skin, lungs, etc. The effects and health risks of Nicotine are no different in severity than Caffeine (coffee) In the research I've done so far. The actual causes of death in smokers are generally attributed to Tar (sap from tobacco plant) and Carbon Monoxide (smoke). This is also why vape products are tested as a 95% healthier alternative. Vape Contain no Tar, or Carbon monoxide, but you can (if you want) purchase vape juice with nicotine in them. I don't think eating cigarettes is a good idea because you will still ingest large amounts of Tar which is a proven cause for certain Cancers.
