I just want to make a confession:
I use a vaporizer, my buddy uses a vaporizer, and the night before this episode was released, we watched vape competitions on YouTube and made fun of them because it's the dumbest shit ever.
Self-identifying vapers are just as bad as self-identifying gamers.
There's also a huge structural overlap between "vape enthusiasts" and audiophiles that I'm surprised didn't get a mention in the wrap-up, too.
I would like to mention though, that vaporizers don't use water. They use a variable balance of propylene glycol and vegetable glycerin, abbreviated to PG and VG, where propylene glycol is a thinner liquid that carries flavor better than the thicker, more syrupy vegetable glycerin.
I used a vaporizer to quit smoking, and while it's not as healthy as not putting shit in my lungs, I don't have shortness of breath anymore, and, bottom line: it's cheaper.
Basically, to cut out all the bullshit:
I spent about 60 dollars on the vaporizer, and 40 on the tank. Assuming 5 dollars a pack a day, in a 30 day month I spent 150 dollars on cigarettes, so the vaporizer paid for itself in less than 3 weeks.
30 ml of juice is about 15 dollars at a local vape shop, but it probably isn't that good because it's usually thinned with purified water, which overheats, and you can get 100 ml for the same price online, which lasts more than a week, depending on your habits and coil resistance.
Sub-ohm vaping, to me, only has the appeal of a higher "cloud" output because the density more closely resembles cigarette smoke, but I do get self conscious about how I look because of how stupid vapers are, and it's asinine to turn it into dick-wagging because a lot of it comes down to hardware.
A 1.2 ohm resistance coil produces less vapor than a half ohm coil because that's the basic fucking property of voltage and resistance. Personally, I prefer .5 ohm because the time between "firing" the vaporizer with the power button and vapor production is significantly shorter at lower resistances.
At 3mg/ml, I have to refill my 7ml tank once or twice a day, meaning it's about the same nicotine intake as cigarettes. I use ceramic coils (around 3 dollars a coil) because traditional coils are steel wire touching a cotton "wick," while these are steel wire touching a ceramic tube touching a cotton wick, which means they last longer and don't take on a burnt flavor after a week. They're cheaper, essentially. I bought 10 in August.
The juice I use is 70%VG/30%PG because heat affects viscosity, and ceramic coils run hotter, so a higher vegetable glycerin concentration is necessary to prevent sucking the juice through the cotton and into your mouth. This will only burn you if you're a dumbass cloud chaser.
The airflow openings on a tank are useful for catering to how you inhale . "Wide open" direct to lung is for cigarette smokers, and smaller air flow mouth to lung is for cigar smokers, essentially.
Most of those guys don't even use nicotine (or flavoring), so that they can more easily inhale and exhale a large amount of corn mist and feel proud about something.
Good juice, to me, is something that doesn't make me feel like I'm huffing candles to get a buzz. It also shouldn't cost as much as fine wine.
As for safety, Li Ion batteries are only dangerous when they're used in an unsafe matter. The all-encompassing vague doom warnings are just liability against people who clean electronics with a relatively sharp knife and alcohol, and they don't reflect the real-world danger vaporizers pose, though the Galaxy Note 7 is a good reminder that shit happens.
Hopefully, this doesn't come across as white-knighting for an embarassing culture, but more as a little pamphlet for the day you'll have to explain, "No, I get it, and it's fucking stupid."
There were some misconceptions in the episode because of how insufferable "vape culture" is, and I don't think that the valid criticisms in the episode deserve to be treated as unfunny or ignorant should there be the highly likely scenario a vape master swoops in on his Goku cloud to decry the persecution of vapor flutes.
Also, someone please convince Warner Bros. to reboot Final Destination, if only for the scene where a vapor lord gets his mod shoved through his face by an air bag.
Edit: sorry for the long post, but I think this point of view was lost in translation.
People have allergies. If your juice has a known common allergen, don't blow it in public. Don't even do it outside in public. Epi-pens are expensive, and you're a fucking asshole if you're blowing artificial cinnamon clouds all over the place without worrying about the well-being and rights of others. Even if it's a bar that allows smoking.
Cigarette smoke isn't a surprise variable in a lot of bars, but there are "generally-regarded-as-safe" flavoring additives that have the potential to kill someone, and members of society, no matter how few, don't deserve the existential dread of accidentally inhaling an artificial flavoring they're allergic to.
