I quit smoking some 25 years ago. But maybe the nicotine of the nicotinamide of the Skoal I still chew will have a redeeming quality.
I know, I know it maybe unhealthy. Just saying. It’s a habit, but as Twain said “quitting tobacco is easy, I’ve done it many times.”
Cheers folks
Actually, nicotine and nicotinamide are very similar chemically. They both bind to specific cell receptors that enable transferring the molecules into the cell. The problem is that when nicotine, which is harmful to cell DNA, binds to cell receptors it blocks nicotinamide (NR, NMN), which is beneficial to the body and slows ageing, from entering the cell. This is one of the reasons people who smoke often appear to age prematurely. They are.
