The lady at the tobacco store told me that Smokey Mountain is bad on ya. She heard that it caused an irregular heart beat. Anyone else heard of this?

I've never heard of it.
If it is true, it is probably to a much lesser extent as nicotine.
It is also less expensive than Cope, Skoal, Kodiak, etc...
It is also not addictive like the aformentioned products.
Consider the source. Someone at a smoke shop, who wants you to buy tobacco products for the rest of your life.
Think profit has anything to do with what she told you?

Yeah, but I was asking her to stock SMC for me. But you are probley correct.

Still... SMC is a tool for quitting. Most people use it and eventually stop. Tobacco growers/mongers expect you to buy it for the rest of your life, and make a good living on your addiction. More money in tobacco than non-tobacco. I believe SMC was developed by quitters.

Agreed. I went from 8 to 10 dips of tobacco to 2 to 4 dips of SMC per day.

I had high blood pressure before, so I check my blood pressure and heart rate every day, at least twice a day. Since being off dip and on SMC my blood pressure has dropped to normal and my heart rate has come down over 20 bpm to a normal rate, and no irregularity in the heart beat. My monitor does notify me of irregular heart beat.

What could be the source of this though is the Guarana as an ingredient in SMC. Guarana is a natural stimulant found in a plant of the same name. It can have a very powerful effect on folks, especially if they are caffeine sensitive, and that could possibly lead to an irregular heart beat. However, for most of us, it should only be a little natural energy booster.

As for this SMC stuff, I'm loving it. It's doing what I need it to do, and that's be a tool that keeps me from caving. If I want a dip right now, I can shrug it off, but when I get that "I NEED A DIP" feeling, the SMC has been able to step in and relieve that crave. And less and less do I feel I NEED a dip.
