Cold Extraction & Nicotine

[CraftyZA]

Hey guys.
I've done a cold extraction and the results blew me away. (I tested after 2 days, by directly dripping on my helios.)
I've added 2 parts PG, to 1 part black cavendish pipe tobacco.
Extraction is now at 4 days. Have not sampled it again.
I'm aiming for 7 days.
Once I have it filtered. How can I kill the nicotine in it?
Anyone got an idea of more or less how much nic will be in there?

I know I can take the filtered liquid and heat it to kill the nic, but that sort of defeats the whole cold process.
Osmosis may work, but that will never get it to 0

That really depends on multiple factors... Primarily how much tobacco you started with in the soak, and the nicotine content of that tobacco.(2 to 1 doesn't tell me much) The currently accepted standard is ~1.5%, scientific literature seems to imply 1%-3.0% being common for fully dry commercial tobacco. Apparently some strains go as high as 6%, this is not likely commercially available.

So I'd say maximum would be to take 80%(efficiency) of 3%(maximum content) of the # grams you started with. Or multiply starting weight with .0225 for worst case total nicotine content. Then divide that by the total # ml's you used in the extraction (say 100 ml).

So if you started with 100 grams and extracted with 200ml:
Max: 100 * .0225(80%*3%) = ~11 mg/ml
Min: 100 * 80% * 1% = ~3.6 mg/ml

Keep in mind this is talking Nicotine, not really mentioning the additional 5%-10% of minor alkaloids, but this is also pretty lose approximations. It would be reasonable to add 5% to these figures if you are talking all tobacco alkaloids.

Again its worth noting this is not detectable via titration because the alkaloids are naturally found in the form of salts, not in freebase form which the titration kits are testing for by forming salts.

I'm not sure anyone has found a good, reliable way to remove the nicotine in a NET soak without also removing the volatile terpenes (what makes it smell/taste). Heating it will kill just as much of the flavor as it will kill the nicotine. If you did something like 10 grams of tobacco in 100 ml of VG then its nicotine content is pretty small (.73mg/ml - 2.1mg/ml).

Excellent reply! I thought the nic would be much higher than this.
I can just as well leave them then?
Considering the nic is not freebase, so uptake will be even slower than what vaping already offers. the quantities you mention there are so small that it will not make a real difference.
The pulp is now at 11 days. Going to take another sample today on a clean dripping atty.
