I tried them, and really there is not much out there nothing that i could recommend.

I'd say stick with NET. I've tried just about everything out there, and found nothing that convincingly fakes the flavor of tobacco.

Yes, that's it. It's my go-to flavor.

Sounds interesting, just ordered all three to give it a try. Thanks!

Sorry, wall of text here because of the detailed procedure involved, if you’re not up to trying your own extraction you don’t need to read

To 1. I’m a chemist, I plan on doing a more extensive extraction than one most would be able to easily do on their own, but if you’re a layman other than your DIY experience, and you’re open to trying to make a NET yourself, you have options you can easily and relatively cheaply do at home in your kitchen.

I did find this method, the second procedure listed in this link, most of the way down the first page, it doesn’t look to bad after a quick skim. Only things I would change is to actually measure the volume of VG you add total so you know the actual content and can accurately calculate final PG/VG ratio. And use 95% grain alcohol instead of 40% abv vodka, and the PG each at a concentration of 10% by volume of the final solution, remembering the EtOH will evap off (if you use 50mL of VG to begin with, that would be 5.5-5.6mL each PG and EtOH then at this step). Also I’d heat for closer to 30 minutes to make sure all the EtOH is gone when you’re done the first time around, just be super duper careful while heating, first time doing this tek maybe have a fire extinguisher on hand even just in case you let the solution start to boil. After the first pass through heat you’re fine sticking with 10 minutes. Finally, during step 4, don’t just add VG to top it off, add a proportional amount of PG and EtOH to match along with it. Same in step 8. except no EtOH added since you’ve already evaped it off.

Not sure if you’ve tried anything like that before and not really sure how effective it would be to get as specific of a flavor as you’d like, but it might do the trick for you.

2. I’m not entirely sure how commercial NET flavors are made, or if that would be substantially different than either my planned or that linked procedure (and my alterations to it above in 1. As well as after this paragraph) in terms of crapping up the coil, but these techniques could affect the coil much differently than commercial products. By my best guess, since you’re steeping tobacco directly into your base solvents then filtering well, it won’t be too bad, probably not as bad as extracts that don’t filter as extensively, but likely still noticeably worse than non NET commercial flavors.

A couple alterations to the procedure that should help this factor even more:

Once you finish with the heating stage, you’re probably going to be left with a super-saturated VG heavy solution with all of the alcohol evaporated off (well actually 0.31mL or less of mostly water from the 95% EtOH will still be present, but that’s negligible and safely vapable). The super-saturation is going to fall into suspension, with much of the solutes staying in colloidal suspension thus not being able to be filtered using normal like coffee filters or whatever. But there will still be a lot of crap that can be filtered like that and would be a bitch to deal with in the next step. So filter using the coffee filter method once or twice while still warm, then let it cool.

Once it’s cool, and you filter it 2-3 more times, I would use a 50-100mL luer lock tip syringe, a syringe filter, and a blunt tip industrial dispensing needle (definitely 18g or less, but as low as you can find to speed up the process) to pull up the mixture, then deposit it in the container you’ll steep it in. Much more effective, and easier to handle tactilely, than holding cotton at the tip, as well as causing you to lose less dissolved solution in the process. Plus those materials are all cheaply available on amazon. Taking out the needle when depositing the filtered solution into the container will likely help but probably not noticeably so. I would filter using this method 2-3x as well, optionally tossing the filter for a new one each step (depending on how gunked up these filtrations make it).

This might be a tad time consuming depending on how large of a syringe you get, gauge of needle, pore size of syringe filter, number of filtrations, and total solution volume. But compared to the cotton method you’re going to yield more volume, and this extract will end up a lot cleaner vaping. Not sure how commercial NETs would compare either way, or if commercial NETs would benefit from a similar micro-filtration method, but that might be something else to try if you don’t like this method.

One note to keep in mind using the EtOH extraction: I don’t see any reason why the nicotine would not be extracted in addition to flavorings. And this would primarily be freebase nicotine with a small portion of natural salts with poor bioavailability through the lungs. However the nicotine content of your final solution depends on some factors too. So the total nic content of your flavor solution is going to be very close to the total content in your original tobacco sample, but it will be diluted throughout the entire extract solution. Pipe tobacco tends to have 3-5% nicotine by dry weight, so if you weigh your original tobacco sample you can easily guesstimate nicotine content by volume of your final solution. This solution may also contain some carcinogens, but it will be nowhere near as harmful as combusting, and most likely will be a bit less harmful than common chewing tobacco or skol type products. Commercial NETs apparently don’t contain any nicotine, but would still likely contain a similar amount of carcinogens depending on exactly how they’re made.

Sorry for the long comment, I’m not even sure if this is info most DIYers might already know. Just wanted to be very detailed in case this is new info for you or anyone else reading. This is probably as close you can get to a much more extensive (and dangerous without lab experience, and possibly a little expensive initially for equipment if your extract is not for sale) lab extraction, and it should be relatively effective, but again not sure exactly how well the nuances of the flavor your looking for will be up to your standards.

Good luck, lemme know if you’ve got any questions on this procedure if you wanna give it a shot!

EDIT: forgot to mention that when prepping your original tobacco sample, you should grind it up in like a food processor or something, that’ll allow for best yield when extracting

Yep, especially 2. is an important point for me. Stixx or Juice Cabin (UK) do some decent filtering, but MTL you easily need 10% for a lighter tobacco NET and no matter what kind of lab filter was used, it becomes a gunkfest pretty fast.
