LSD (acid) and magic mushrooms (psilocybin) are well known for their psychedelic properties, but they aren’t the only such drugs that people use recreationally to “trip.” Ketamine, also known as “Special K” or “Vitamin K,” has emerged over the last few decades to become an increasingly popular drug that produces a psychedelic experience. This drug, however, is prescribed by doctors and veterinarians as an aesthetic and has recently been used to treat drug-resistant depression in humans with success. In medical settings, ketamine is highly supervised owing to its temporary mind-altering properties and to ensure safety. When abused, ketamine is quite dangerous and a high dose comes with various risks that some users refer to as “falling into a K hole.”
