    Any idea how pure the various sources of juice are?

    I started down this path as a "Nicotrol" user. I was getting "pharmaceutical grade" nicotine sold by Pfizer and prescribed by my doctor. (fully FDA approved BTW) It worked great. But had some probs.
    CONS
    1. Tasted like medicine (not so bad --truth is analogs don't really "taste" good.)
    2. Cost a fortune. ($264 for 168 cartridges) (10 mg.-- 4 mg deliverable) equiv approx 2-3 cigs in my expereince)
    3. Prescription expires, hassle with pharmacist, only avail 168 at a time, one vendor general pain to get refills.

    PROS
    1. Ingredients on package
    2. Verifiable vendor
    3. Clear explanation of side-effects

    anyway, My question is
    Do folks have any sense of where this juice (as sold by various and sundry) is being made, how pure is it what else might be in it?
    Also curious, is it made by extracting the nicotine from tobacco?

    for comparison i link the known ingredients of nicotrol (can't post link due to newbie status)
    Nicotrol NS and Nicotrol Inhaler| Pfizer: the world's largest research-based pharmaceutical company

    followed by the known additives in cigarettes (at least according to wikipedia) (i'm a new poster so no links--ez search)



    NICOTROL® Inhaler (nicotine inhalation system) consists of a mouthpiece and a plastic cartridge delivering 4 mg of nicotine from a porous plug containing 10 mg nicotine. The cartridge is inserted into the mouthpiece prior to use. Nicotine is a tertiary amine composed of a pyridine and a pyrrolidine ring. It is a colorless to pale yellow, freely water-soluble, strongly alkaline, oily, volatile, hygroscopic liquid obtained from the
    tobacco plant. Nicotine has a characteristic pungent odor and turns brown on exposure to air or light. Of its two stereoisomers, S(-)nicotine is the more active. It is the prevalent form in tobacco, and is the form in the NICOTROL Inhaler. The free alkaloid is absorbed rapidly through skin, mucous membranes, and the respiratory tract.
    Chemical Name: S-3-(1-methyl-2-pyrrolidinyl) pyridine
    Molecular Formula: C10H14N2
    Molecular Weight: 162.23
    Ionization Constants: pKa1 = 7.84, pKa2 = 3.04 at 15°C
    Octanol-Water Partition Coefficient: 15:1 at pH 7

    I don't have direct answers to your questions. I have some links that might help in answering some of your questions.

    In many cases you can look up the ingredients and sometimes the extraction is explained at the website of the manufacturer. Sometimes not.

    Here's one thread on nicotine purity and some on the extraction you might find interesting.

    .... also check before and after the post linked. Nick O'Teen is owner of Decadent Vapours and makes some of the Ejuice for Totally Wicked including their 'Platinum Ice' which is the purest form of nicotine juice, I believe. Some others may have duplicated the purity but I don't think anyone has exceeded it.

    Platinum Ice 54mg Mixing Juice-PG or VG-30ml

    check the certification docs in the images.

    Besides being an excellent amateur chemist, Nick O'Teen also has some great flavors that he mixes with the the pure nic and aqueous glycerin which are my top 5 ejuices. 80% of what I vape is Decadent Vapours ejuice, and in my experience, translates into a consistently clean vape true to the flavors listed.
