I have been having a real vaping day - cleaned atomizers for the 1st time and spent hours mixing diy liquid/juices.
1) How dangerous is nicotine? I usually use 18mg but I got a bottle of 100mg (EcigXpress) and I am wondering if I should be wearing gloves or a mask.
2) Does anyone know of a conversion table (or?) showing how much nicotine I got from smoking Benson & Hedges and Marlboro Blend 54? I vape much more than I smoked so I am wondering what the actual meaning of so-called "low" or "medium" nicotine content as it relates to smoking tobacco.
3) During my first face-to-face meeting with a vendor, I thought she was hyping their "Organic" nicotine. [I may have smirked at the idea of organic poison] Now - I am wondering whether there are some nicotine extracts out there that should be avoided?
4) does nicotine remain in solution better in VG or PG?
4b) can you freeze nicotine extracts? (I am thinking of stocking up)
TIA - You folks have been a big help.
This is a pretty dangerous topic here, and if a mod pops by, I'd suggest that this gets moved to the DIY forum. If I understand correctly, ECF doesn't endorse or support any vendor that carries nic concentrate over 36(?)mg. Once you get past that threshold, it gets more and more dangerous. The actual ammount of toxicity of Nicotine will vary from person to person, but generally speaking, it's 0.5-1mg/kg body weight. I'm around 230 lbs, which comes out around 105kgs. That means that something around 105mgs of nicotine will make me -very- sick, possibly even leading to kidney failure and we know where that goes. Tolerance is a little higher in smokers, but...why risk it. Nicotine also absorbs through skin contact, and it absorbs very quickly. If you were mixing 100mg liquid without gloves on and somehow accumulated less than 1ml on your skin during the mixing session, you're in some trouble. 1ml isn't a lot, as you probably know from measuring stuff. I throw at least that much Diet Coke away when I think that the can is empty and I've shaken it to try and get the last drop out.
Yes, you'll get some people that say they mix with their tongue and use it as a lotion before they vape it. I don't feel that it's worth the risk. I've got enough problems without being sloppy with a dangeorus chemical.
Also, nicotine can build up in the atmosphere, which is especially true for higher doses. You really don't want to be handling it in an enclosed environment. Make sure that you've got plenty of ventilation. If you do, a mask shouldn't be required, but it's still not a bad idea.
Okay, now I'll hit your questions.
There isn't a converison table. The FDA is too busy trying to lump this in with analogs to bother studying it. We can make some educated guesses, but that's all they are. The general rule around here is to vape until you don't crave an analog anymore. We were self-medicating with cigarettes, this is the same deal. I was a pack-a-day smoker, and I started on 18mg liquid, didn't have any trouble switching over, but I did/do vape way more than I smoked.
Nicotine extracts to avoid: That's a tough question. There's a giant thread around here somewhere that someone went ahead and tested the nicotine content of a bunch of the concentrate that people had and found that the numbers on the bottles were more or less wrong, to a dangerous degree. Someone had some 240+mg nic.... Check out the DIY Sub-forum:
DIY E-Liquid
PG and VG retain the nicotine similarly. I don't think that there have been any tests done on the matter. Most people use a mixture of somewhere between 80/20 and 20/80 of PG/VG, mostly because they do different things to the vapor. PG tends to carry throat hit and flavor better, whereas VG makes better clouds and mutes the flavor a bit. The nicotine will stay good for quite a while, depending on how you store it. I store my concentrates in a chest freezer, and all my mixes are in a dark cabinet. The concentrates will not freeze, they do thicken up a bit because of the cold, but they won't freeze, so glass is perfectly alright...as long as you're not going to be smashing it in there. I use 36mg, btw.
Hope this helps,
