That goo is propylene glycol, the main liquid component of most vape juices. It's also used in theatrical fog machines, which are generally considered safe to fill a room with and then let the general public wander around in. It's also used as a carrier for inhalable medications, including asthma inhalers, so medical professionals are OK with someone in respiratory distress inhaling it.

Obviously neither of those use cases are directly comparable to someone who is heavily using a vape, especially a "cloud chaser" who is intentionally going after thick clouds, so there are certainly unknowns but there's not really any reason to expect it to be horrible.

There have of course been issues with specific additives found in certain vape products turning out to be irritating or harmful but that's a very different matter from implying the whole concept is harmful.

Of course inhaling anything that isn't either clean air or a medically validated mix of oxygen and inert gases is not ideal, but it's also worth remembering that these are primarily an alternative to smoking either cigarettes or weed. If someone who would otherwise be lighting some rolled up dried out plants on fire and inhaling the combustion products is instead getting the active ingredients they crave delivered by inhaling an aerosolized goo that's generally considered safe to inhale I'd say that's a firm positive.
