I'm a little confused by methoxetamine (MXE). I've read it is an opiate and read that it isn't. Ketamine is known for, among other things, lowering tolerance to opiates. MXE being similar to ketamine, does MXE do the same or the opposite? If MXE is an opiate itself, then anyone taking it in hopes of lowering opiate tolerance would be doing the opposite...actually increasing there tolerance...right? Does anyone know or have a clear answer to this? Does MXE lower opiate tolerance like ketamine?
