There's a widely available natural substance that's proven to protect the brain from any number of serious diseases, including Parkinson's and Alzheimer's.

So naturally, the powers-that-be are doing everything they can to keep it away from you -- and if you do take it on yourself to get it, you can expect dirty looks and fake coughs.

Yes, it's the nicotine found in the tobacco leaf, and because it's so politically incorrect to get it the natural way, the drug industry is racing to create synthetic smoke-free versions they can patent and charge top-dollar for (and with no tobacco tax to burn into the profits).

The latest is called EVP-6124, and in a six-month study it managed to help preserve and even improve cognitive function in dementia patients. Those who took a placebo, on the other hand, actually got worse.

It's no secret why it works. People with conditions such as dementia often lack the neurotransmitter acetylcholine, causing immune cells to go berserk and attack the brain itself.

Nicotine, however, can actually replace acetylcholine and restore order in your noggin. It's so effective we should tell our farmers to ditch the soy and get back to growing good old American tobacco -- but you know that has a snowball's chance in hell of happening.

So the way I see it, you've got two choices here. You can wait for the Big Pharma version, which will probably be less effective and more dangerous than the real thing.

Or you can light one up today.

Despite what you've heard, natural tobacco has never been proven to cause cancer, emphysema or any other disease. And along with protecting the brain, tobacco can help PREVENT cancer, ward off heart disease, improve digestion, and more.

I recommend a quality cigar after meals. You can even make like Slick Willie and not inhale -- just take the smoke into your mouth, where the cells in your cheek will absorb everything the rest of your body needs... especially your brain.
