It’s more of a cliche, I don’t think anyone actually does it, but it shows up in those cropped images of tweets people post on reddit. Downvotes should show right next to the upvotes (at least, on desktop). Is a nice feature to show both, so if it’s like, negative 1, you can see, Oh it’s actually negative 10 and positive 9, that is like 50% dislike ratio. Feels a lot better knowing its a split crowd.
edit: A word
I think the main thing is that you can get a more intense nicotine hit, probably because it is easier to smoke higher concentrations, so I assume it is more addictive in that regard. It’s a smoother smoke and you don’t get that residual nicotine in the mouth that you would at high concentrations of the freebase. You can always just try it out, most vapes are compatible with both juices, although they might be optimized for one over the other.
