That overlay is a recent addition to the video, it wasn't there previously.
There are 4 major alkaloids in tobacco:
Anatabine
Anabasine
Nornicotine
Nicotine
Anatabine is being looked at for helping people with Alzheimer's.
Anabasine can be lethal in large doses. But the concentration in tobacco is really low (0.008 - 0.030 milligrams per gram of tobacco). You would suffer nicotine poisoning before being killed by Anabasine.
Nornicotine on it's own, isn't bad, but when tobacco is cured Nornicotine turns into N-Nitrosonornicotine, which is a carcinogen in lab animals, but no studies have related N-Nitrosonornicotine to cancer in humans for some reason.
Nicotine, there are books and books, about it and it's effects.
The big question is which of these alkaloids, or combination of, are the rest of us addicted to? No one knows, yet. Since nicotine accounts for 90% of the alkaloids in tobacco, everyone assumed that is what EVERYONE is addicted to. But obviously, there are those of us who don't fall into that category, since we can vape just nicotine and never get satisfied (personally I've accidently vaped to much to get nicotine poisoning a couple of times). Also we are also the small percentage of people who nicotine replacement therapies (NRT) (patches, gum, lozenges) have no effect.
The odd one is Chantix. For some reason, they have found that Chantix works on some of us who don't respond to conventional NRT. Mainly because it blocks several different receptors in the brain (not just nicotine). It's just that the side effects can be really bad (suicidal tendencies). Which is why there has been a renewed effort to look more deeply into tobacco addiction and try to find out which other alkaloids are addictive.
