At low doses, Ketamine is a mild, if weird stimulant. It is in the same class of drugs as PCP (Angel Dust), DXM and nitrous oxide (laughing gas). At medium to high doses, it becomes a very powerful paralyzing psychedelic. Its effects are like a combination of cocaine, cannabis, opium, nitrous oxide, and alcohol.

When Ketamine separates or dissociates the mind from the body, the brain is freed from the usual business of reacting to sensations from the body. Perception increases to fill the gap vacated by the senses and gives rise to Ketamine's more mind-expanding effects.

At low doses, Special K increases heart rate and blood pressure. Taking a larger amount has the opposite effect, leading to depressed respiration.

Some users report feeling nauseous after taking Vitamin K. Vomiting may occur, as well. Using the drug on an empty stomach may help to minimize this side effect.


Onset of the K Effect

The K effect is very rapid. If you use a small amount of Special K, you may start off feeling dreamy and like you are floating outside of your own body. Your arms and legs may feel numb in the initial stages of the trip. In 10-20 minutes you may find yourself hardly able to move and, at higher doses, the experience has been described as even approaching out-of-body and near-death experiences.


Peaking on Special K

At the height of the experience, you may experience dazzling insights, hallucinate and even feel yourself communicating with forces, entities and elements you were never conscious of before. The world you see in your mind may be very detailed and in some cases, you may feel that you are sharing your visions or thoughts with other people who are nearby.

The visual hallucinations that K users experience may include images, as well as the sensation of falling or even flying. It has been likened to a religious experience, with some users seeing and communicating with a Higher Power.

Users often fall into a deep trance state. Most people are sitting or lying down during this phase. Their eyes may move sightlessly from side and side, and their bodies may assume bizarre postures. Try to tell someone about it and you're likely to mumble monosyllabic and nonsensical inanities.

Some people find it a life-changing and even spiritual experience. Others find it a lonely and unemotional experience. It may even be terribly frightening. Whatever you make of it -- it's intense.


Coming Down from Ketamine

Usually, a Ketamine trip only lasts between 45 and 90 minutes, regardless of dosage. The experience can be much shorter if you have high tolerance. The effects wear off very rapidly.


Side Effects of Tripping on Vitamin K

If you've ever had an operation under anaesthetic, you'll recognize that lousy post-operative feeling after a strong Ketamine trip. There are few other side effects other than this general drowsiness.

You might feel wiped out, a bit achy, and not ready for anything too loud or too complicated. Sometimes you may feel rather disoriented or even a bit shell-shocked, as Ketamine is a very extreme experience at higher doses.

It's not uncommon to have a memory lapse about the details of the trip. This side effect is similar to that of not being able to remember a dream the next day, even though it may have been a very intense one at the time.

Many people feel energized after a Ketamine experience and have a strong urge to move around, dance or stretch.

Long term, some users can be so overcome by what they regard as the superior reality of Ketamine-land that they can retreat from the real world into the K-world. In a type of reality flip, the visions they see while under the drug's influence feel more real and meaningful than what they experience in the brick and mortar world.

The results of a study, published in the Hong Kong Medical Journal, following a small group of users who had been involved with the drug over a four-year period concluded that K was responsible for causing bladder and kidney damage. Users complain of K-pains when coming down from a trip and may turn to opioids to deal with their discomfort. Urinary tract infections are very common among Vitamin K users, and drinking cranberry juice may help to prevent this side effect.
