Hmmm. You get some interesting results when searching for "chloroform substitutes"

Basically what these very experienced individuals (its a BDSM forum) say is that 1) Chloroform is an old drug that may not even be available anymore, 2) it's not safe, has all kinds of horrible consequences like liver damage, kindney damage, sores on your skin if it touches exposed skin 3) There isn't really a safe way to know somebody out without repercussions, although there are other drugs you can use like GHB, rohypnol, rufanol, valium, ( I think these are date rape drugs, some of them are illegal?)
Somebody suggested the only safe way to knock somebody out is with hypnosis.
The internet really is a fascinating place.
