ketamine
written by Paul Nesbitt & David McCandless
the basics
Ketamine is a fast-acting 'dissociative anaesthetic'.
It works by shutting down the body's nerve paths, leaving respiratory
and circulatory functions intact.
Since 1970, it has been popular in medicine in the UK
and US and all over the world as a safe anaesthetic for children and
the elderly.
It is also used by vets on animals for short operations, hence it being
dubbed a "horse tranquiliser". Find out more about Ketamine's
use in medicine here.
Street prices vary, but Ketamine can
be bought for as little as £35 per gram.
appearance
Ketamine comes in three main forms. The most common form is white powder
which is snorted. It looks like cocaine but is smoother and less likely
to form hard rocks or a flowery texture if damp.
Most users start out by taking Ketamine in powdered form as it allows
them to introduce themselves to the drug with small amounts.
tablet
Ketamine also appears intermittently in tablet or
capsule form, often masquerading as a brand of Ecstasy with the same
meaningless 'dove' or 'mitsubishi' logos.
K pills are usually very diluted and cut with a stimulant like ephedrine
(a natural amphetamine-like chemical) to produce a mildly trippy, speedy
effect.
Ketamine sold as Ecstasy may be the origin of the "smacky
pills" legend.
liquid
Ketamine Hydrochloride, intended for use as a hospital
anaesthetic, is sold in liquid form in small 10ml bottles, often with
the brand names Ketaset, Ketavet and Ketalar.
Some recreational Ketamine users inject this liquid. We
strongly advise against injecting Ketamine intravenously. You could
pass out immediately.
Avoid drinking it too. Liquid K is very hard on the stomach. Profuse
vomiting is possible. If you pass out, you may choke on your vomit.
Do not mix with alcohol.
ck1
Ck1 is a combination of cocaine or crack cocaine
(smokeable cocaine mixed with sodium bicarbonate) and ketamine. The
cocaine roots the user in the real world and counters the tendency for
higher doses of K to send you into a conscious, paralysed state.
See mixing
with other drugs for more information
effects
At low doses, K is a mild if weird stimulant. At medium
to high doses, it becomes a very powerful paralysing psychedelic. It
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.
onset
The K effect is very rapid. In 10-20 minutes you
may find yourself hardly able to move and, at higher doses, even approaching
out-of-body and near-death experiences.
peak
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.
Users often fall into a deep trance state. 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. Whatever you make of it - it's
intense.
comedown
A Ketamine trip usually 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
after effects
If you've ever had an operation under anaesthetic,
you'll recognise that lousy post-operative feeling after a strong Ketamine
trip. There are few other after-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
disorientated or even a bit shell-shocked, as Ketamine is a very extreme
experience at higher doses. 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. We're not kidding.
See Tales
From The K-Hole.
setting
At high doses, because its effect is essentially
an internal and introspective experience, external stimuli like loud
music or TV are not particularly satisfying, nor conducive to a good
trip.
This is not the case at low level doses, when it acts
more like a stimulant.
in the brain
Ketamine's effects on the brain are well documented.
It mainly binds to and blocks glutamate receptors (also as N-P receptors)
all over the brain. Glutamate is an excitatory neurotransmitter. It
turns on cell activity and is part of the computer-like on / off mechanism
that underlies brain activity.
Ketamine blocks glutamate activity, giving rise to either
entire cell bank shutdown in some brain areas or changes in the way
cell clusters integrate or interpret incoming data in others. Overall,
the result is the much famed K-Hole effect: certain brain parts go into
temporary hibernation, mainly the senses and physical sensations, while
others - imagination, and other unnamed perceptions from the depths
of the mind - are amplified.
dangers
Thanks to its use in medicine, Ketamine is relatively
safe compared with most recreational drugs. There have been numerous
human clinical trials and its effects, long and short term, are well
documented and understood.
Nevertheless, recreational drug use is not controlled
medical use
overdosing
Overdosing on a self-administered dose of Ketamine
is nearly impossible because it has a wide safety margin and you will
pass out well before it can kill you.
However, Ketamine is not a good drug to take outside the
home. You're quite likely to fall down, get run over, or at least make
a complete fool of yourself.
Talking, moving or even going to the toilet is not easy;
it's important to be in a safe environment with, ideally, one non-participating
friend.
physical dangers
At high doses, Ketamine can be physically incapacitating,
even paralysing. Make sure you extinguish all cigarettes, candles and
anything flammable that could be knocked over.
long term dangers
Some emerging research suggests that heavy and prolonged Ketamine use
can cause brain damage, in the form of 'Olney's lesions' or 'vacuoles.'
However these vacuoles were found on rats injected with
Ketamine and experiments on monkeys have failed to produce similar results.
This is probably one reason why the Federal Drugs Administration (FDA)
in the US has not removed medicinal Ketamine from the marketplace.
dosage
Ketamine has a very steep dose-response curve. It
is a very different drug with very different effects at higher doses.
However, unlike other psychedelic drugs like LSD, Ketamine
is a short trip, lasting no more than an hour and a half from start
to finish. The duration is not affected by the dose. So if you're not
enjoying yourself, it's all over pretty quick.
common effects for snorted doses
low doses (10-75mg)
A small line of Ketamine, up to 50mg, will induce the mild, trippy euphoria
that has led to its sale as an alternative to Ecstasy. Smells and tastes
seem muted. Visual perception and sense of touch amplified.
medium doses (60-125mg)
everything in slow motion, buzzing or ringing in
the ears, disconnection from your surroundings, loss of co-ordination
and in less than ten minutes you can find yourself hardly able to move.
large doses (100-250 mg)
You're in the K-Hole where it is physically difficult
to do anything other than lie in a near-comatose state and stare at
the ceiling. In this state some users report life-altering insights
about the meaning of life. Others are just scared.
mega doses (250 mg+)
You're unconscious.
oral doses
Swallowing Ketamine results in slightly different
effects. The drug goes straight to the liver when it is processed into
norketamine. Norketamine has greater numbing, sedating and pain-killing
effects and will make it more difficult to walk or move around. The
psychedelic effects on the mind also come on slower and the whole experience
can be much longer, up to 4 hours. Snorted doses also trigger more 'out
of body' effects than oral doses.
injected ketamine
Unsurprisingly injected Ketamine is quicker acting
has significantly more powerful effects. Effects after an intravenous
(iv) injection begin after 30 seconds and last around 10 minutes.
We strongly advise against intravenously injecting
ketamine. You could pass out before finishing the injection.
Intramuscular injection (im) effects begin after 2-4 minutes
and last up to an hour.
addiction & tolerance
Ketamine is not physically addictive,
but, psychologically, thanks to its desirable effects and short duration,
it can be extremely habit forming. There is now clear evidence of tolerance
and dependence.
It should not be taken if you're anything other
than emotionally stable and robust. Many regular drug users are completely
suprised by the "first addictive psychedelic they have ever encountered"
tolerance
Bodily tolerance rises quickly with regular use and lasts for about
three days.
Frequent users require increasing doses and many report
a diminishing of the Ketamine high over time, so that the effect becomes
more like a combination of cocaine and cannabis.
Chronic users - mainly those who inject - develop something
close to permanent tolerance so, after months of use, are unable to
experience the psychedelic effects. Ever again.
withdrawal
Ketamine does not appear to produce withdrawal symptoms in chronic users.
There are anecdotal reports of tension, twitchiness, poor attention
span, and restlessness in abstinent long term users, but this may be
due more to the sedative norketamine (a breakdown product of ketamine)
lingering in the blood stream.
mixing with other drugs
Like all anaesthetics, Ketamine is not a good mixer.
Respiratory depressants like alcohol and valium are particularly risky.
At anything above a low level dose (50mg or less), Ketamine is so powerful
and complete that for most users, combining it with any other drug only
detracts from the experience.
alcohol don't - can cause nausea and vomiting; can also depress

drug tests
Ketamine is not tested for in standard or advanced
drug tests.
However if a specific test was requested, norketamine,
the breakdown product of Ketamine, is detectable in blood and urine
for 7-14 days and "sometimes far longer" in heavy users.
legality
In the UK, Ketamine is not a controlled substance under
the Misuse Of Drugs Act. This does not make it a legal high. It can
only be obtained by a doctor's prescription. So if you were arrested
with Ketamine, you could be prosecuted under the Medicines Act for supply
without a licence.
UK police have had some success prosecuting under "conspiracy
to offer to supply MDMA" laws.
in the US
In August 1999, after a high profile campaign and its demonisation as
a 'date-rape' drug, Ketamine became a Schedule III controlled substance
in the United States, federally illegal to possess without a licence
or prescription.
frequently asked questions
» So Ketamine is a legal high then?
Not exactly. You can't buy it over the counter or
just go and ask your doctor for a prescription. Ketamine is restricted
to use in hospitals by the Medicines Act as a prescription only medicine.
Unauthorised supply is illegal and if you are apprehended
by the British police with a wrap of 'Special K' powder you will have
some explaining to do. Although it is not a controlled substance under
the Misuse Of Drugs Act, under the Medicines Act you may be fined and
even imprisoned if you have a sufficiently large amount of the drug
that you are deemed to be supplying.
In the US, Ketamine is a schedule III drug. Possession
and supply is illegal without prescription.

» I heard that Ketamine
is just an animal tranquiliser withdrawn from use on people. Isn't that
a sign that it's dangerous?
Ketamine is not a tranquilliser. Ketamine
is used in hospitals all around the world 'for the induction and maintenance
of anaesthesia.' It's recommended for us on children and geriatrics
because it is very safe and gentle anaesthetic. However, all anaesthetics
are very powerful and potentially dangerous drugs, and using them recreationally
is a whole different ball-game.
» Is Ketamine just another
name for Angel Dust (PCP)?
Ketamine is very similar in its chemical make-up
to PCP (Phencyclidine) but is shorter acting and less toxic. Both drugs
were patented by the same pharmaceutical giant, Parke-Davis, for use
as general anaesthetics.
PCP stopped being used with people because of unpredictable
side-effects, including psychotic behaviour. Legal production of PCP
has since been discontinued. Ketamine has no history of producing such
psychotic side-effects.
» Is Ketamine addictive?
Ketamine does not appear to be physically addictive,
but recent research and anecdotal reports do point to Ketamine being
extremely habit-forming, especially for injecting users. See our section
on addiction & tolerance
for more details.
» Is it true that some
ecstasy pills are really just K?
This is indeed true. Although Ketamine is very different
from Ecstasy, at low doses taken orally and combined with a stimulant
like ephedrine it can approximate some kind of trippy euphoria.
» Can you smoke Ketamine?
Smoking powdered Ketamine in a joint is not especially
pleasant and will not noticeably speed up the onset of the Ketamine
effect.
» Is it easy to overdose
or die taking Ketamine?
Ketamine deaths are extremely rare. You will pass
out long before you could administer a lethal dose (4.5 grams and above).
However Ketamine is a powerful hallucinogen and large doses are not
recommended for newcomers to psychedelic experiences.
» Can regular use hurt
me?
Ketamine is relative safe drug compared to other
recreational substances. It has been used in medicine all over the world
for over 20 years and its pharmcological, short term and long term effects
are well known. But like any mind-altering drug, heavy and prolonged
use of Ketamine can at the very worst destroy any sense of what is real
and leave you uninterested in the relatively mundane, everyday world.
Letting any drug take over your life is extremely dangerous.
» Will Ketamine show up on a urine drugs
test?
Highly unlikely. Ketamine is not one of the substances
tested for in drug tests. For more information on drugtest see our guide
here
» How can an anaesthetic
be so psychedelic?
This is down to the way that Ketamine works on the
brain. As it disconnects your brain from your body, the mind takes over
with its imagination. Ketamine has been compared to a waking dream.
Enthusiasts claim that when you no longer have the interference of every
day bodily sensations, you open up unused senses and spiritual insights.
You can find some detailed explanations of brain effects here.
» Is it true that you
can only get the full Ketamine trip by injecting it rather than snorting
it?
Afficionados claim that injection is the only way
to feel the 'true' Ketamine high. In it's pure form, Ketamine is produced
commercially as a clear liquid for intramuscular (into a muscle) injections.
It is designed to be injected by medical professionals, and we cannot
stress strongly enough how dangerous any kind of self-administered injection
is. Don't even try to inject K intravenously (into a vein), because
you'll pass out before you finish the injection.

What is the 'K-hole'?
This describes the peak effect of a strong Ketamine
trip when users' bodies are virtually paralysed, while the sense of
self feels removed from the body.
