I've done Xenon a fair number of times, it is definitely the Rolls Royce of inhalants. I'd recommend it to anyone as long as you can divert a little and aren't paying for it yourself. If you don't have unlimited amounts of money, it simply is not worth it.

If you're looking for a great NMDA inhalant experience I'd recommend another classic 19th century anesthetic, diethyl ether. It is extremely simple to produce -- heat everclear and sulfuric acid together and distill. Adjust the PH afterwards. Anyone can make diethyl ether. The actual meat of the ether experience is actually on par with Xenon. I'd say the only element that makes it worse is the aftertaste.

It's still a tradition among Lemkos in the Carpathians (Slava Ukraini!) to drink ether. Drinking is a little trickier, as the boiling point of ether is lower than your body temperature. You should chew and swallow some crushed ice beforehand, and also serve a bit in a shotglass with some crushed ice and lemon shaved ice to offset the taste. I've also found pina colada mix to be a great accompaniment. If you're just starting out with ether I recommend just inhaling the vapor.
