For DIY juicers: nicotine extraction article
It's from 1977, but they did use a water extraction on tobacco. It's pretty technical for most of it, but they did show that 2 pounds of tobacco extracted with 1.25 gallons of water yielded .25 gallons of drained liquid at 4.56 grams per liter (same as milligrams per milliliter) and a second extraction of the same tobacco with 1 gallon of water yielded 1 gallon of drained liquid at 3.72 mg/mL. Method was soak the tobacco in the liquid for 30 minutes at room temp with occasional stirring then drain through a mesh screen. So that part's easy.
The concentration here would be low, but volume reduction by boiling could make something higher, to be diluted with PG or VG of your choice.

Fair indicator that the "tea" method DIY brews should be usable as a base in terms of nicotine content, if not somewhat weak. Or, at least as safe as a liquid solution of a known poison gets.
Of course, use at your own risk. Really, I just ran across this and thought I'd put it up for some vague idea of how much nicotine may be in the homebrews.
I believe the only way to determine the approximate or exact amount of nicotine content using a DIY method is in the reduction process. I read somewhere that the extracted tobacco liquid could be reduced down to nicotine crystals that would be scraped out of the container boiled in. Of course in the end result, you won't have much in dry weight. But, you can then determine the amount by milligrams or grams.
I should have saved the site to favorites, but at the time(before I realized I could use cigar tobacco) I didn't think it would be useful to me. Besides, I don't think I would be comfortable with having a massive amount of tobacco liquid boiling in my home with my children.
