Question: "Is it really unsafe to combine ketamine and MDMA?
Erowid's Answer: "... Because of the legal and social issues around the use of illegal drugs, there hasn't been much research done on the practical implications of various drug combinations. We can't say that the moderate combination of ketamine and mdma (ecstasy) is safe, but we can say that we have heard many reports of individuals using this combination in a manner similar to what you describe and we haven't heard of any significant physical risks with it."

"It's true, like nothing I have ever done before. I'd recommend anyone to try it at least once, simply for the pure mental expansion it has allowed me to adopt, and for the weirdness of the entire experience. It takes your body and mind, and launches them beyond the human imagination and what it is normally supposed to accept, providing an interesting and unique trip and offering perspectives I will probably have never encountered otherwise."
