Hi Damage,
Got your message about this, and thought I answered you here but I realized I didn't... I'm sorry...
Here we go:
How I did it was this way:
I took a pouch of pipe tobacco and soaked it in water (filled just enough to cover it) and let it soak with a cover on it, for one week... After this, I drained it into a small pot, and using plastic gloves, I squeezed the tobacco to get all of the liquid out.. Simmering it until it turned into essentially a thick syrup..
I then added this to VG and a bit of vodka to thin it out...
Vaping it, I could taste the flavor and it was really nice..
Now backtracking, my mother has been obsessed with "Perry Mason" since it was on tv since the 60's.. I hated the show to such an extent that it ended up being a punishment to me.. My mother would make me sit in front of the tv and watch it.. After the show, I would have to explain the episode to her in detail.. One episode had a woman murdering her husband for his money and she poisined him with nicotine, essentailly doing this.. So I thought that this would produce nicotine and add some of the flavoring of the particular type of pipe tobacco I used.. I had also searched online and saw a number of posts using the same directions and saying that this would produce pure nicotine..
Later I had found out through the forum and a few other e-ciggie forums that a few chemists who vape did the same thing and tested the results and it ended up that this produced nothing but flavoring.. So after I did this and all the posts on being careful since some on the forum thought that I might over-dose myself, someone posted onto the thread the results of the chemists that had done the same thing..
So......... my quest continued and people are still trying to find a way to create liquid nicotine at their homes and I've yet to find anyone who has actually done it and didn't produce just flavoring...
