Regular ketamine use causes memory loss and 'unusual beliefs'

A report released this month by University College London has show a link between long term ketamine use and short term memory loss.

150 people were followed for a year to see if changes in their ketamine use could predict changes in their psychological well-being, memory and concentration. Of these 150 people, 30 were taking large quantities of the drug nearly every day, 30 were taking it recreationally (once or twice a month), 30 were ex-users, 30 used illicit drugs apart from ketamine and 30 did not use any illicit drugs.

The study found that the heavy ketamine users developed an impaired short-term memory over the year as ketamine use increased. Interestingly, the recreational ketamine users and ex-ketamine users did not differ from non-users suggesting that occasional ketamine use does not lead to long-term harm to cognitive functions and that any deficits may be reversed when people quit using the drug.

However, all groups of ketamine users showed evidence of unusual beliefs or mild ‘delusions’, with these being greatest in the frequent users and least in ex-users. These include conspiracy theories.

We'd like to hear if you've developed any unusual beliefs or indeed had mild or not so mild delusions. Spoke to aliens? Stared into the abyss? Please share...

well being as i dont take ket i can only talk from the rumours i here, but i believe a few people were under the impression that ket is so good, the horses actually want it back.

personally i think they can keep it.


oh and the fact it shrinks your bladder and over use can lead to carrying a piss sack every where with you for the rest of your life.

i've experienced some wierd things in a k hole (obviously). rooms changing shape, paper folding itself into weird shapes, thinking the downstairs of my mates house was an underground burrow and i was some kind of beetle (!) and being able to levitate myself and float through the air.

all great fun while under the influence, but i haven't taken to sitting in a darkened room with the curtains closed and tin foil on my head.

Lol, I've seen a few people have a bad time, I've had to babysit huge men who can't stand up and help them go to the toilet like invalids. Both me and my flatmate have had both good times and bad. I'm not a heavy user any more though, and a run in with the stable manager is unlikely. Memory does return, and life's colours do return also, but it's a hard rut to get out of when life is dull and K is all that makes it interesting. It's makes your selfish, you develop an addictive personality... Something which thankfully is fading over time, and I lost the art of decent conversation without the mention or use of drugs.

I'm all better now though. Yay!

The more I take Ket the more ive started to believe in alternate reality's, I've watched films such as the Matrix, The Butterfly Effect, The Fountain, and relate to certain surreal scenes of the movie. This isn't helped by my intact of Salvia which can at times be a lot more intense than Ketamine. The first time i started getting unusual beliefs from Ket was after my first trip to Ibiza in 2006, I believed i had met jesus and Ibiza was a play ground where both god and the devil could run free. But honestly though, I'm not completely mental..i realize these thoughts are mainly drug induced, but it has definetly opened my mind to the possibility of these things maybe being a little bit true.

I've had plenty of gud times and bad on ket. The one thing that i can remember from taking ket is thinking about the meaning of life, ya know like where we come from and whats it all about. Also i try working out the big bang theory in my head (which i have no chance of doin considering im not as bright as stephen hawkins) The most extreme bad times i've had on it was taking to much and listening to my heart race worrying that i was about to have a heart attack (quite scary) that may have also been influenced by staying up and taking any amount of pills in ibiza for 48 hours non stop lol

If I'm being true to myself I would say that I am a ket addict. however, being a student I can currently only afford a 3 gram blow out, once every fortnight or there abouts. More and more now to be fair it's just going down hill & I'm not doing myself any favours.

I believe that medicinally in sensible doses, ket can be beneficial. It's a thinking drug. It's not for everyone like but it stimulates and opens the mind so in my belief "ket therapy" could nurture those with autism and distract and / or to help along people suffering with emotional stress from something bad happening to them e.g someone dying as it pushes you towards looking at things from outside the box. This is affectionately named by hardcore ket cadets as "ket logic" and some swear by it. To be fair it is usually right but sometimes it can get it wrong. It's only your mind. It can't give you any new information and if you realise something which you've actually got wrong, you can feel so strongly about it that you act upon it and the shit hits the fan. I can only remember this happening to me once but the consequences were dire.

I often will have an epiphany of genius creativity on ket but struggle to get it down on paper. fist in hell if i could transpose these thoughts and visions directly onto a media format which could be viewed on a video screen I wouldn't have to worry about money for a long time but it doesn't work like that. assuming I can remember it when I come round, it's a minimum of 2 days before my brain properly comes back enough for me to string together complete sentences let alone be articulate enough to write creatively. after which time the moment is gone. that or ill get full on writers block. it can be quite frustrating.


long term effects...

I've fucked my nose up. Since I was 15 I have solely used my left nostril to sniff ket. There was method to my madness as I am left handed and In the club its quicker and less dodgy to key it. I can't key in the other nostril with either hand without spilling it. any other drug yeah fine but not ket cause the angles are all wrong!!! tell me you've been there! lets laugh cause it is funny. not so much in the cold light of day. 8 years down the line and the flesh in the left side of my nostril has dissolved away to a fraction of it's original thickness. every time I sniff (nose permanently snotty - bad weather and long term defence from the drugs i keep sticking up there) even without drugs the soft side sucks in and flattens. the other side doesn't as I've hardly ever used it. It's blatently obvious. I have deformed my face. the left side has gone floppy and isn't as plumped up as the other. It even feels softer. I've completely stopped using that nostril now but what do i do? quit and have a lop sided nose?! or start using the other nostril to even it out a bit?! I need to quit but at the same time i don't wanna look like a junkie and reconstructive surgery is not in my income bracket.

The effect it has on your internal organs...
I once bought in bulk and snorted half a bottle to myself over a weekend. my back started hurting which i put down to bad posture. it progressed into crippling lower back pain which didn't go away when I lied down. My dad's a nurse and when i told him what I'd done he explained that it was nothing to do with my back. What I was feeling was kidney pain. I didn't even know where my kidneys were situated before but I can genuinely say that I have never experienced anything like it. CRIPPLING agony which I wouldn't wish on anyone. not even my worst enemy. it takes the knees from under you. I spent the best part of a week spakrd out on my bed. It took Tramadol (a mild tablet form of morphine which should have been for my dads knee) to enable me to move as far as the toilet. It did do the trick like. to be fair it went straight to the source and took the edge off but its not something a doctor would generally dish out so others might not be so lucky.

I've seen 2 of my friends (female, I'm told it affects girls worse) have different but just as bad problems. One is younger than me and it attacked her bladder that badly that she started to wee herself and she had 2 go hospital. she'd wee'd the bed that many times that we had to get rid of the matress. The smell (of a poorly run nursing home) was overpowering and spread throughout the house.
my other friend has been hospitalised 6 times in 6 months, latest time being 8 days from it attacking her stomach. She is too scared to tell them what she's been doing though so they cant really do a lot for her.


bizarre experiences...

When I take enough ket I often have very spiritual experiences. I have seen the universe from every angle and have had more than one out of body experience where i find me, my soul, a spirit entity in the form of a bright white light looking down at my body. I have also found myself on a completely separate plane to the room i was in just minutes earlier. I feel so enlightened by these experiences that emotionally I find it hard to come back. the "comedown" from these experiences, apart from withdrawal symptoms is a bout of depression and / or suicidal thoughts.
the thought track is always the same... "we shouldn't be here. why are we here?? how are we here?? how could we possibly exist?? and floating above me is a voice saying "well there's only one thing for it then. you'll have to go and kill yourself. go on do it! go on then". this voice is so persuasive i can feel my body trying so hard to comply. I would never go through with it as Im strong willed and very strongly apposed to acts of suicide. my believe is it's weak and there's always another way. It does make u think though. being not far off immune I no longer appreciate how strong ket actually is. It's a powerful drug and people should be more aware of the consequences. I'm not saying don't do it cause I can't imagine my life without it. it's nice and to be fair that's the point. there wouldn't BE a point otherwise. I'm just saying that you don't think of the consequences until they materialise and smack u round the face. it's not funny.

with regard to the spiritual experiences. are they real? are they in my head? maybe I am really close to god from being that close to death??? the American Indian's used peyote for spiritual enlightenment. maybe it unlocks the door?? maybe i'm full of shit. to be fair no one can know for sure until they die. what say u?

"ket therapy" could nurture those with autism

interesting.... what do u study?? & have u actually read any journals to support this? & if you have could you share it with me plz??

or to help along people suffering with emotional stress from something bad happening to them e.g

i still really dont agree with this tho, i think it's a very dangerous line towards addiction!

Hello VikiKity.

To be fair I am talking about my own mind and personal experiences / observations. I cant back up the second one with evidence. It was an opinion and yours is damn right because to be fair as I already stated I'm an addict. your point makes me see that I'm likely to be wrong there.
I'm probably just talking out my arse but I strive for truth and say what I think and the above is a genuine account of my experiences.

I do believe strongly in "Ket therapy". The autism thing... I have asperger's syndrome which is a form of autism. my brain is very active and ket actually helps me. my mind is constantly thinking s**t ALL the time. I can never switch off or chill and if there is something bothering me then I wont sleep. I can't sit still. I am a victim of my own brain. I find ket constructive in that it stimulates my mind. every last single thought is processed on fast forward and is over and done with in one go. I come out of my hole and can move on, usually with a great epiphany of what I can do to help things along.
I swear by it but things do affect people differently. ket logic makes a lot of things in life make sense to me which would normally confuse the f**k out of me.

I'm a theatre technician hence am a creative person. not a logical one and definitely not a medic. I've got a fair idea because I've seen first hand what it can do to people and what it's done to me.

I know someone who was on anti depressants for a while. He got to a stage where he didn't want to be on them any more because they were rather strong and left him pretty dopey all day long. He decided that, instead of doing what the doctors would have told him to do, he wouldn't bother weaning himself off over a period of weeks, but would do it over a period of about 1 day. Around a day or so after he took his last AD pill, he had an epiphany and thought he had found the meaning of life or something. He started to write a book about it. This lasted about 3 days, and then he realised the drugs he was on had made him FUCKING DELUSIONAL!!!

It sounds to me like you're thinking on the same lines Ben.

ok the original report (bare in mind iv not read it) im assuming is talking about a trait known as schizotypy - it's not really a new finding to find a connection between this & ketamine use. Personally I would say that ketamine isn't the only drug which is likely to give u a high schizotypy score, I think it's very likely that amphetamines would do exactly the same.

Schizotypy is basically having eccentric thoughts - but u have to consider that a lot of drug users will be quite open minded in the first place, & so maybe that is the reason why they also demonstrate belief in conspiracy theories & such.

I might look into finding out if there is a connection between autism & ketamine use tho, iv never heard of one before & i think interesting that uv mentioned it
