SWIM knows about both substances, though he's never mixed them specifically. He has, however, mixed opiate pain killers and ketamine and will draw some inferences. When combining pain pills with ketamine, SWIM felt the pills were superfluous and decided to stop wasting them.
Ketamine is a pretty overpowering experience and when injected intramuscularly (IM) or, less commonly, intravenously (IV,) many other drugs would be lost in the mix. Heroin's main effect is relaxation, and ketamine does a pretty good job of this itself. Taken in conjunction SWIM would expect a slightly "dopier" ketamine trip.
Insufflating/snorting ketamine in conjunction with heroin might yield more interesting results, but it's a stretch for SWIM to comment on this as he doesn't snort ketamine. He imagines the effect to be a "trippier" and more psychedelic version of a normal heroin experience.
The danger in the combination lies primarily in the fact that heroin, unlike ketamine under normal circumstances, depresses respiratory function. Heroin and ketamine are routinely used when doing surgery on humans as an anesthetic combo, but it must be stressed that this is done by an anesthesiologist, or at the very least an attentive person with some medical training. Using this combination recreationally, the dangers of repressing the respiratory system become more clear and present.
The other danger is that both ketamine, and to a slightly lesser degree heroin, can be pretty physically debilitating. Nodding out in a ketamine fog, a user is likely to be unable to respond to the demands of the physical world and all the dangers arising from such a situation must be guarded against.
If a person is inclined to experiment with this combination, it's highly recommended that they do so in the company of a clear-headed and attentive sitter.
Any SWIY have personal experience with the combo they care to share?

Ketamine and heroin is one of SWIM's all time favorite combos but also a VERY dangerous one. Besides the dangers of respiratory depression and physical debilitation that Beltane mentions ketamine is also known to decrease opioid tolerance so taking ones usual dose of heroin could be potentially lethal.
The main reason SWIM discontinued the use of this combo was it's addictive potential though. Both drugs can be quite addictive on its own but in combination SWIM felt from the start that the effects could easily become ones sole goal in life as pathetic as that may sound.
Experiencing the surreal land of Nod through the twisted lenses of the K dimension is a fantastic amusement but due to the above SWIM would strongly advice against experimenting with it.
Should anyone feel inclined to risk becomming this weeks front page casualty of drugs in search of the ultimate high SWIM would add that in his experience the factor to be most concerned about is the heroin dosage. After some cautious experimentation he would usually dose half to 2/3rds at most of his usual heroin dose IV and let the effects of that settle in and then take a K-hole dose of ketamine IM. This should definately not be attempted without a trip-sitter!!
Be very carefull with this combo. Defentely have a sitter and be accustomed to both drugs before trying together.
My friend is a big K user but was an H virgin.
He had been doing K IM for a number of hours, several hits over a few hours, then decided to snort a tiny amount of H, which caused respiratory failure and a trip to A & E. Not sure how common this is and what exactly caused it, but the danger is definetly there!!!
Back when Swim was an IV user, he and a couple of his friend had come up with a concoction that they called "K-Balls".
This was heroin, cocaine, and instead of water, they used liquid ketamine from a vial to mix the heroin and cocaine, then IV it.
Swim in no way recommends trying this as I can only imagine how dangerous this combination could potentially be.
Swim did this several times when he was fairly new at IV use and was pretty much willing to try anything. The term "young and dumb" comes to mind.
Swim most often reached a state of black out, with little to no memory using this combination. During his final experiment with this combo he lost consciousness for a few minutes. Once he regained consciousness, his friend told him that his face had turned bright red, nearly blue, and that swim was screaming as if in he was in a state of extreme fear. This frightened Swim away from further experimentation...
Again, Swim can not stress enough how much he does not recommend trying this, but he saw this topic and thought he would share his experience.
