What the Yuck: Does acid cause brain damage?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Is it true that acid causes permanent brain damage? I'm worried because years ago I took it once!

I wouldn't worry. Some past LSD users experience occasional flashbacks - hallucinations or reliving of a "trip" - that last a few minutes and aren't permanent.

Rarely, you can develop frequent distressing flashbacks or visual disturbances called Hallucinogen Persisting Perception Disorder. But if you haven't experienced either of these problems yet, you're probably okay.

In the short term, using LSD can lead to psychosis or severe depression, but those conditions happen at the time of use, not years later.

Are you worried because you heard that acid stays in your system forever? Don't believe it; the drug is usually gone the next day.

    I did acid and shrooms at different times throughout the college years...........always preferred shrooms – more natural feel – but they were both amazing experiences.

    If you're wonder the damage that acid can do, read or watch about Syd Barrett of early Pink Floyd. LSD pretty much destroyed his music career and eventually his life. Tripping ONE time in life is enough, if you are in the process of soul searching or spirituality searching. Acid is not a party drug.

      sorry Mike. i've been there, done that (a lot between '73 and '78 and a couple of times for "old times sake" in '85) and it's obvious to me you know not where of you speak. i never reccomend drugs (including alcohol) to anybody but my extensive personal experience possibly has enhanced my life possibly not but there are, a quarter century plus down the line, not a single reason for any regrets about lsd

      I have to agree with Rick on this one – been there done that (91 thru 98). No lasting impact here. Graduated college with a 4 year degree and I am now a senior programmer for a fortune 400 company. No depression, nothing.
      I never regret my time in the 90s. I had a blast. Met fantastic people. And... I became who I am today. Wouldn't trade it for the world.

      Just because some didn't get long lasting brain damage, it doesn't mean all people won't, especially if they have a family history of mental illness. If people do have a history or genetic predisposition to mental illness LSD may not be a good idea.

      Syd Barrett was destined to be mentally ill before he ever did any drug. Scientifically indefensible remarks like yours do more than just give drugs a bad name, they give sobriety a bad name.

      Syd's contemporaries all pretty much agree that he had underlying problems long before he took drugs. His father passed away when he was 14 and his mother became overprotective of him as a result. All the stresses of fame and fortune combined with the drugs did him in. I'm sure acid was one of the many things that pulled the trigger, but I don't think it was the sole cause.

      Citing one example that is questionable at best doesn't prove your point. Syd Barret had psychological problems before LSD ever entered into the equation. It would be easier to argue that lsd actually helped his music career and his well being.

    LSD works almost the opposite way that "Ecstasy" does. They both manipulate serotonin receptor signaling but almost oppositely. Both drugs are dangerous and curiously, repeated use of both drugs leads to profound depression. However, I believe research should continue with both drugs since they can be useful in a controlled setting supervised by a physician to effect receptivity to either emotional input or sensory input. Don't ever ban research on anything. That's just dumb.

    A lot of people here are talking about how they had acid 300 times like it's something to take lightly. Look, hallucinogens are like any other class of drug, there are many variations. Take stimulants, caffeine and crack are both stimulants are both stimulants, but their effects are wildly different. I've used that point to argue that some hallucinogens are safer than others and shouldn't be treated the same, but most are dangerous and NONE are toys! I've had peyote twice with Native Americans and treasure the experience, but I could clearly tell this was nothing to play around with. Neither is LSD or anything else. If you want to have this experience, respectfully try to find a Native American Church that will allow non-Native Americans, or, if you can, find a tribe in Mexico or South America (that doesn't cater to tourists for a price, that is) and take it their way. But you are talking about your brain here people. Don't take this lightly, and don't just play around with this stuff on your own. Yes, some of the "Horror stories" are just urban myths, but plenty are real, and plenty of people who have worked in mental hospitals can tell you real stories of what can go wrong when people treat LSD and the like as toys or something to experiment on their own with.

      Native Americans are no better qualified than anyone else to administer hallucinogens. The fact that you trust them is the only thing that made your experience seem better. In my 20s and 30s I used hallucinogens (acid, mushrooms, and peyote) dozens of times. Having a trusted person that is not on the drug is a good idea, whether they are Native American or not is inconsequential. as for the long term effects, there have been none, other than fond memories.

      They don't have to be Native Americans, but someone who is serious about the spiritual value (or medical, if it's therapy), very, very careful, very mindful of the dangers, and well aware of the need to be very sparing with the use of it. These days, that's mostly Native Americans or the few doctors licensed to use such drugs. But I didn't mean to imply that there is something in the DNA of Native Americans that makes them the only people fit to use them, just that in this country they are among the last people left with a cultural tradition that gives them the respect needed to gain the enormous benefits and minimize the many potential dangers.

    Well it is said to open your mind, and I can agree with that, (dozens of trips when I was young). A study of LSD trips in Baltimore is showing a increased general well being that last months. It would be good for some people to do, but others that I would call not mentally strong it could be a bad experience. (They should stick to mushrooms).

      That doesn't surprise me, but I'm surprised they use LSD. There are far safer, similar drugs. It's like with many other drugs, a carefully supervised medical dose made in a lab is will have a different effect than when it's made in a bathtub and taken by someone who thinks it's a toy.

      Some much ingnorance in regards to LSD its crazy, first off the nonsense about it being physically harmful has essentially been disproven. From a mental/emotional standpoint, it is like any other intense experience in your life, you have to be mentally prepared.

      And some of these postings worried about it being made in a bathtub obviously have not clue about chemistry and probably think it's made from old Foster's beer.....Stop feeding on all the propoganda, maybe it's you who is missing something....

    I literally don't know how many times I tripped. I never had a bad experience and there are no aftereffects for me. It isn't for everyone. Some people are just not mentally strong enough; they are the ones who freak. I totally came at it as a Disney ride. I knew I was tripping, I knew the whole time when things were freaky that I was tripping and I knew approximately the time it would end. Not everyone is mentally stable enough to do that and get lost in the experience, but it is the same with alcohol or any other drug. Those are the people who turn into d!cks when they drink. I haven't dropped acid in 15 years, but I would do it in a heart beat if I could get rid of my wife and kids for a day and find the stuff. Do people even make it anymore?

      Let's assume this is made up. But the kids are ALMOST grown and my time is my own.
      So the issue is how long until I have to drive somewhere.
      Yes, LSD is still out there, go hang out in a Phil Lesh concert parking lot.
      But then go get the shrooms. Shorter duration means it fit into modern life.

    "Are you worried because you heard that acid stays in your system forever? Don't believe it; the drug is usually gone the next day."

    As a matter of fact, LSD is mostly gone by the time the trip starts. LSD causes a chemical change in your brain, and you "trip" until the change goes away. However, the LSD itself doesn't stick around and actually participate. That's why there isn't a blood test for it.

    People do lots of foolish, risky things and sometimes get away with it. Nothing to be proud of. Unfortunately, many aren't so lucky and suffer the consequences the rest of their lives. Far better to invest your time and money into something that improves your life and the lives of others.

    I've tripped in the 80's and 90's – probably about 105 times on LSD, bunch of times on 'shrooms... Did I get flashbacks? Nope. Saw some black spots floating around on occasion, but that was probably floaters in the eye... From acid, I gained an immense amount of introspection – learned to look at things in a different way, and not worry about stuff so much.

    I never had a bad trip – but I have a strong mind. I knew how long it would last, and just went with it and enjoyed it for the 12 hours... That said, I've seen some weak-minded people lose it and cry for 12 hours – those are people who shouldn't use acid – ever.

    I always considered it to be a mood-amplifier – however you feel, multiply that by 10,000 for the next 12 hours.

    Have you ever laughed for 3 hours straight? I and a buddy of mine did – tripped our balls off. Had a great time. We both graduated, both have graduate degrees, and great jobs. We're productive members of society.

    Do we trip now? Nope. Got too old, have responsibilities and families, and can't be completely out of it for 12 hours to trip, then sleep it off for another 18 hours...

    But we do have our memories – and we cherish them.

    If it caused drain bramage, we'd be vegetables for over 20 years by now......

    Acid can be good and bad at the same time. Most people I know did it in high school and college. This is inherently dangerous because we were driving around and interacting with general society. It is good though because it gives a "big level perspective" of one's life that was probably not known before. The closest thing I compare it to is flying over my neighborhood for the first time in a jet plane. I saw how really small my existance was within the big picture. That perspective is inportant because it made me aware that I could do so much more. That said, I did it about 10 years ago when I was in my 40's and it was horrible – too much work.

    In summary, make sure you stay out of a car, in a controlled environment, and use it judiciously – it is not a casual thing. I have seen peoiple that treated it as a casual thing and they were fried – and of course SOME PEOPLE HAVE NIGHTMARISH TRIPS so it is a risk.

      I don't know, when I did it, driving came easy. It didn't have effect on my ability to drive. It caused me to have an infinite amount of patience, such that I could tolerate anything, even Republicans. I doubt the stuff out now could make me tolerate today's Conservative. This breed must be stricken from the earth.

    I did orange sunshine, purple micro dot, MDA blotters, smoked big fatties, and did hot rats of Acapulco gold in the late 60s.
    I went on to own three companies, retired a multi millionaire when I was 49 and still smoke a dobbie before I go to bed every night.

    Couldn't tell you how much acid I've done, I did a lot when I was in high school and in the army, and had loads of fun I havent done any in over 10 years, I'll catch a tracer every now and then (only people who have done acid will know what I am talking about), but that is about it, no flashbacks. My wife is about half my size and she used to do the same amount I would and she has never had any flashbacks either.

The baby boomers are the most immature, self adsorbed, self righteous bunch of scrotum lickers to ever curse American society. They also happened to drop LSD like it was skittles. Coincidence? I've done acid by the way and it didn't hurt me as far as i can tell. By all means give it a shot but using it like weed or booze is foolish. Trip a couple of times and be done with it. After those first few times all acid will teach you is how to be completely self absorbed.
