    Prue Talbot conducts study on ECF posts, grossly misrepresents facts

    You are given the title "conspiracy theorist" by two types of people: those that cannot see, or those that don't want you to see.

    Am I a real DIYer?

    If it doesn't even cross your mind to buy pre-made juices when you run low, you are definitely a DIYer. How good of one is subjective, but if you like to vape your own liquids, you are certainly good enough! I also tend to make juices of single flavors, then sometimes mix them together in a...

    Prue Talbot conducts study on ECF posts, grossly misrepresents facts

    The first study based on ECF posts lacks any shred of scientific rigor, on multiple levels. It is laughable at best, and has little chance of being published, in my opinion. The second study with carto particles seems more scientific, and potentially concerning on the surface. Without...

    Seems Yahoo has picked up the story on the Utah fight

    It's a blood bath. Supporters are having a feeding frenzy. I have not seen one comment supporting this insane tax move by...who is that...is that Pee Wee Herman?? Sure looks like him! Sorry, couldn't resist.

    UK: E-Cigarettes "...can cause more harm than smoking."

    Oh, snap! This may be a first. Good on the DM for correcting this! Now if we could get other publishers from printing lame articles in the first place.

    Drops per ml?

    Drop size depends on viscosity as well as the hole size it is coming from. graduated syringes are in general remarkably accurate and precise, since they are used primarily for medicine. Never use drops for nic, especially 100 mg/mL. You will almost certainly get the nic level very wrong. ECX...

    Nicotine Comparisons

    Thanks, Cy! They are a PITA to do right, especially the standardization steps. The problem can be if there are other alkaloids in the nic, since they are all amines and will contribute to the overall nicotine "amount". Also, I can't do flavored liquids. I titrated some heavily flavored...

    Distilled water in e liquid?

    My general recipe for VG juices is %flavor + %water = 20-22%, give or take. And yes, I use distilled water. But then, my max flavor is 12%...more than that is too much PG for me (most flavors are a PG solution).

    Nicotine Comparisons

    No worries, JA! :) I might have said it once, during a time when that was the case. Sort of like food...sometimes you like pasta, sometimes you like baked chicken. Because of the work I do with the industry, I have a large variety of nics, and they all have their own place. I am trying an...

    Nicotine Comparisons

    BE has more taste than WL regular. There is a slightly gamey bite to it. WLR is more subtle...to me there is a slight hay and caramel taste. But I never had an issue with BE in flavored DIYs. Indeed it was what I, and many others, used for about a year. In some samples of RTS I get almost...

    Nicotine Comparisons

    Happy B-Day, Cyrus! Someone said my favorite unflavored is RTS. Not sure when I made such a definitive statement, but I vape a variety of nics unflavored, including RTS, Vermont Vapor, WL regular, ECX, and Box Elder. Right now I am enjoying Box Elder 18 mg VG with 20% distilled water. I...

    Nicotine Comparisons

    The VG-Ice I have is smooth and low TH and pepper compared to the MFS I have...but I think MFS from that time (2010) was legendary in its pepper. John at WL is a fanatic about nicotine accuracy. I have worked with him, and he has an on-site chemist for titrations. I takes it VERY seriously...

    It comes in a "fresh-tasting minty spray"

    PG is very slightly less acidic than water. Not sure what you mean by 100x more alkaline, but that woold be 2 pKa units, and PG is only 0.25 pKa units less acidic than water. One would not even notice such a small difference. Nicotine, however, is about a billion times more basic than...

    Wizard Labs

    True, and I must admit a few of my bottles in the freezer are colorless glass...since I have some that the eurodroppers fit. Its mostly for protection from light while the bottle is in use. Even so, it is mainly sunlight that is the issue, specifically UV.

    Study--what is in the vapor we exhale?

    I think ppm here for air sampling would be micrograms/L of air, rather than per mass of 1 cubic meter of air. But even with this distinction the value of 4.2 microgram/cubic-meter would be 0.0042 ppm, or 4.2 ppb. Very low indeed. I would ask not why ecigs are as high as cigs, but rather why...

    Wizard Labs

    Several reasons. Mostly that PG or VG can leach plasticizers from some plastics. This not only has you ingesting them, but could result in plastic cracking. WL recommends long-term storage in glass, but for safety reasons ships in what is most likely a polycarbonate plastic (will leach...

    It comes in a "fresh-tasting minty spray"

    Not really. The negative effects of PG are mostly a chemical dehydration, sometimes (less often) an actual allergy (itching, rashes). The HCl and NaHCO3 are there to buffer at a particular pH, most likely to get an optimal mix of nicotine free-base form, and its salt form. Nic free-base is...

    Best Vanilla flavoring?

    Indeed! Creamy = custard notes. Acetoin or acytylpropionate. The none custard noted vanillas are more light and airy. I'm a big fan of TFA Bavarian Cream. To me it more of a creme broulee, but a very nice flavor. Also, I have found with vanillas, less is more. vanilla can easily become...
