Dwindling numbers of cloud chasers doesn't really surprise me for a several reasons:
-- The vaping industry has greatly evolved. 6 years ago; one's choices were weak cig-a-likes, ego type cartos, or full on cloud-capable rtas
(yes; I am being overly simplistic). Today; there is a much broader spectrum of choices.
-- A minority of inconsiderate vapers gave vaping a black eye, by fogging up inappropriate locations indiscriminately; making it more difficult for all vapers, even the courteous ones.
-- Conspicuous/copious cloud production further reduces the declining number of places a vaper can acceptably vape.
-- Cloud chucking can be expensive, if one is routinely vaping premium priced e-liquids. Going through $10-$20/day is just as expensive as smoking.
-- High liquid consumption often leads to higher demand for maintenance. Replacing batteries, replenishing liquid, replacing/rebuilding coils and wicks. Not everyone wants to contend with this... especially when there are lower-maintenance options.
-- Trends are leaning toward smaller, more discrete devices, like single coil MTL, and pods.
-- Convenience (portability, maintenance, battery life) are beginning to outweigh sheer cloud production. Flavor seems to be a more popular focus(?).
-- Increased availability/popularity of high mg/mL (often 30-50mg/mL) nic salt e-liquids is not supported by cloud chasing.
-- I see more folks commenting about feelings of heavy/congested chests, and wanting to reduce e-liquid consumption and exposure.
Don't get me wrong; I am not saying that there is anything wrong with cloud chasing, or the people who prefer it. All the more power to them.
I am only saying I can see why it is not as popular, for
some vapers, as it once was.
