I think this is an unnecessarily polarized admonition. Alcohol is arguably more than possibly-lethal, but many people exercise a reasonable risk calculus that allows them to enjoy it, and even enjoy it to a low level to moderate excess (on occasion), and that doesn't necessarily indicate pathological drug abuse. An unusual medically-safe (in medical contexts) anesthetic generating curiosity about recreational effects and safe use is not unreasonable, and having that curiosity certainly doesn't imply that someone is "not ok!" I'm not saying that Xenon isn't exotic; it likely takes someone with a strong background in less-dangerous inhalant usage (and deep pockets) to use it safely. But there are plenty of exotic substances that people use safely and sanely throughout the world, and telling people off for having interest drawn from a (reasonably balanced, I would say) source ain't the business.
