Decoction as extraction method

Decoction is a method of extraction by boiling of plant material.The method of extraction is very simple:

From snus:

Put loose snus in tea bags, boil, then filter, then boil again etc (Similar to tobacco approach). I’ve also heard that microwave-boiling snus in water for a two-three minutes will yield even better results.

From tobacco:

Guide 1: How to extract nicotine from tobacco:

Water alone will do the job. Just add tobacco to hot water, heat it to boiling, strain off solids, and then filter the stuff.

Boil down the remaining water until it is supersaturated. Then, let it cool slowly. Add a seed crystal or scrape the sides of the smooth container with a glass stirring rod (or a spoon if nothing else is available).

Filter the crystals that form in the solution with vacuum filtration. A good way to do this is by putting a coffee filter in a funnel, then putting the funnel spout-down in a running wet/dry vac.

Guide 2:

This entire process took about 3-4 hours to complete. I would recommend a gas stove or be very careful and patient with an electric stove top. Get some distilled water and a measuring cup. Also filters for a drip coffee machine.

Put the tobacco in a sauce pan (1 quart).

Add two cups of the distilled water. Bring this to a slow rolling boil, stirring about every 3-4 minutes.

Simmer until you have about a 1/3 cup of liquid remaining. It is very important to not turn the heat up to high or you have a bunch of sticky thick useless stuff, or so I have heard.

Let cool about 10 mins.

I taped my coffee filter around the outside lip of a 12oz ceramic coffee cup and poured this mixture into the filter. Some of the juice seeped through, most did not.

I finally, after about a half hour, untaped the filter, being careful to not dump the tobacco into my juice. I folded the filter up and squeezed the remaining juice into the cup. Take the tobacco left in the filter and eat it. (just kidding: P).

Place the left over tobacco back into the sauce pan, add 2 cups of the Distilled water and repeat the procedure.

This time slow bowl until you have a bit less juice (about a quarter cup). Remember to watch this, do not let it boil down too long or you have a thick sticky mess.

Strain it again in a separate container.

Combine the two containers of liquid.

Strain this again back into the sauce pan.

Slow boil again until you have a quarter cup or a bit less.

Strain one more time.

Guide 3:

I myself have been using PGA (95% pure grain alcohol) and a soxhlet extractor to mimic this type of extraction.

I then vacuum filter to.22um while it is still in about 250ml PGA (Started with 20gm of cigar tobacco)

I use vacuum distillation to recover most of the PGA.

I use warm bottom heat to evaporate more of the liquid. It will precipitate out some of the oils.

Re-dilute, re-filter, re-recover and re-evaporate. A lot of tars come out at the filtering step.
You end up with very dark but low solids

Guide 4:

Buy e-juice (liquid with 10% nicotine) and boil down. E-Juice is pretty inexpensive even at $20. per ounce.
