I've actually done this once before, as I was briefly having belly issues and honestly couldn't eliminate the possibility of a parasite.

It made me feel a bit weird for a day or so, but not too bad really. It did slow my cigarette craving for a while too. It didn't outright evacuate my guts as you might assume, also apparently I didn't have any intestinal worms thankfully.

I think the way this is meant to work is that if you do have worms, the nicotine is supposed to shock the little demons into unclamping their jaws and basically evicting themselves.

I'd stand by this technique for survivalists in a pinch though.

Same for 4 tablespoons of salt in a quart of water. This will make you piss out of your asshole your body wants to get rid of it so fast. 30 mins of stomach gurgles, ten minutes of the most liquid to ever come out of your asshole since last you tried to boof a 6 pack, and then you're good to go.

If you did them the other way, kerosene then cigs, well that would burn the parasite out, sure, but the host... well, it might hurt a little.

That's for the marines.

Vomiting won't get them out. If when you vomit you're bringing up matter from where they live then you've got much bigger problems than just a worms infection.

This is field survival manual, meant as a last resort for situations when you’re miles from civilization and neither a pharmacy nor a medic are available.

Of course there are better options out there.

"Ah yes I see the problem. The cigarettes have to be unlit. We'll mention it in the next edition. "

You CAN??? repeat this treatment in 24-48 hours.

Man, you would bring up cauterizing a wound..

Many years ago we had a terrier dog that got shot by a neighbor in her right hip. Thankfully it only went under the skin and came back out like 3 inches away, so no serious internal damages, but the dog's wounds kept bleeding and bleeding..

Dad couldn't afford a vet, but I wasn't gonna just let the dog bleed out either. I got out my soldering iron and cauterized the wounds myself until she quit bleeding. Yeah the dog didn't like it much, nor did she like me very much afterwards, but I successfully stopped the bleeding and she ended up fully healing up with no problems.

Drink kerosene, smoke cigarette, breath fire.

I doubt you're ingesting much of any of it, it's being absorbed directly into your bloodstream through your gums. Actually eating it would have a totally different effect on intestinal parasites.
