people use various recipes for enemas and urine is one that often can arise in fetish BDSM situations. Since SWIM
has yet to meet a single person who has had issues from doing enemas on a semi regular basis of various recipes depending on what was required, having any health problems.
Common problems with enemas is doing them to frequently, or without proper rehydration of electrolytes after.
However since the hypothetical situation we are looking at would require a series of enemas with breaks to test what if any effect is achieved, the urine is still only going to stay inside for 10 minutes or so. That is all that should be required for the colon to make an asorbtion of the contents. Even at 15 minutes SWIM is doubtful of whether this practice could be more dangerous than the use of methamphetamine
itself. Already playing with fire, people like to try new ways with drugs
and ideas to recycle use is common. Safe practice is best to be remembered, lack of freqauency and rehydration with electrolytes.
