Yep!
SWIM tried a DCM extract (~500ml total) on 50g tobacco with 35ml clear household ammonia to free the nicotine. The DCM was fractionally distilled off, the remains dissolved into 15ml water, filtered 2x (again, harder than it sounds, nicotine is full of waxes/tars which are water-insoluble). (I think I should have concentrated the DCM then extracted with brine and citric acid, then basified with ammonia, and extracted with DCM, boiled off, etc. That type of acid/base could have increased the purity somewhat)
Anyways, it was loaded into a nasal sprayer that dispenses 100uL at a time. Dosage was somewhere around 5mg in that 100uL (assuming 4wt% nicotine tobacco, 50% yield). Took one shot, woah.. NASTY taste. 5 minutes later, I wanted to throw up and felt generally ill. 30 mins it peaked, 2 hrs I was back to baseline and felt OK. Yuck!
However, the most important piece of info: NO NICOTINE RUSH.
What am I doing wrong? Is smoking/IV'ing the other way? Swim wants a habit that does not include inhaling carbon monoxide.
