I've been a social smoker for ~15 years; I attempted Juul-ing about a month ago -- had to stop it as I was immediately (from the 1st puff) feeling unwell, super dizzy and occasionally with a massive headache.
Even if this is not linked to any "contamination" of the pods, the amount of nicotine the put in those things is just insane.
Didn't even bother giving the vaper to somebody else, I just threw it away
Yes, the amount of nicotine in Juul pods is absurdly high, and has little variability. Somehow they became the market leader, and a lot of people assume their products to be representative of the industry as a whole. They aren't.
If you want something harmful to ban, why don't you start with products with a nicotine level above 24 mg/ml. Better yet, why don't you REQUIRE them to be made available in a variety of lower nicotine concentrations, including nicotine-free. Giving the user control over the nicotine content is the primary value of vaping for smoking cessation. There is a legitimate public health interest in requiring products to be useful for this purpose.
I hope you tried (or with time will try) an alternative vape rather than continuing to smoke. Juul is extremely high strength nicotine salts liquid - there are plenty of more traditional suppliers of much weaker and more palatable liquids and devices.
Yep I find them to be suuuuper strong. I have a "normal" vape that takes the "juice" and use the lowest nicotine level of 3mg/mL. That is plenty for me!
