Hi Paleophil,
>Considering
>that chewing tobacco can make first-timers nauseous,

Chewing tobacco is different from a tobacco plant:


What's In Spit Tobacco?

Chemicals. Keep in mind that the spit tobacco you or your friends are 
putting into your mouths contains many chemicals that can have a 
harmful effect on your health. Here are a few of the ingredients 
found in spit tobacco:
    * Polonium 210 (nuclear waste)
    * N-Nitrosamines (cancer-causing)
    * Formaldehyde (embalming fluid)
    * Nicotine (addictive drug)
    * Cadmium (used in car batteries)
    * Cyanide
    * Arsenic
    * Benzene
    * Lead (nerve poison)
The chemicals contained in chew or snuff are what make you high.
Tobacco picked from a plant would probably taste like any green leafy 
vegetable. (not that great)

Probably no sicker than brussels sprouts or broccoli.

Maybe he means you don't need much to get all the B's.

As for the vinegar or lemon on the tobacco, it seems common to have 
these on a lot of greens especially in the southern USA, not so much 
in Canada. Most green salads are naked without vinegar or lemon 
juice, aren't they?

The author must be a vegetarian. I haven't come to that part yet....
If apples and pears are paleo you can put the peelings in water and 
let them sit until they become vinegar.
Could that be paleo?
