Addiction Potential Zero physical addiction potential. Not something that makes you want to do it again immediately. Essentially zero psychological addiction potential.
Adulterants Because of its extreme cheapness and potency, the purity of LSD in blotter form is not an issue: either it's lsd or untreated paper. The purity of powders, pills, and liquids cannot be assumed as safe....If there are 200 micrograms of LSD in a tablet, there could only be 200 mics of impurities present even if the LSD was originally only 50% pure (assuming nothing else has been added), and few compounds will produce a significant effect until a hundred to a thousand times this amount has been ingested.
Flashbacks ...it (LSD) is easily water soluble, thus cannot form bodily deposits. Furthermore, it is metabolized and excreted in hours. The bogus "loosened crystal" description in not necessary to explain flashbacks, which are psychological phenomena....
Mechanism ....LSD acts to preferentially inhibit serotonergic cell firing and seems to spare postsynaptic serotnergic receptors. This preference is shared by other similar hallucinogens but in a limited fashion....
Drug Tests No risk. Its not looked for, hard to find, and transient.
Tolerance Acquired rapidly, within 3 days. Tolerance dissipates equally rapidly, without withdrawal, craving, or symptoms of addiction. Cross-tolerance can and is developed between other indole hallucinogens, eg, DMT and Psilocybin.
L = pounds (the "L" comes from the Latin word for pound, libra, and a pound sign "£" is still a stylised L) S = shillings D = pence (the "D" again comes from Latin, this time from the word denarius which was a unit of currency in the Roman Empire)
The basic divisions were:
Hence there were 240 pennies in a pound. Just to confuse things further there were a number of other nicknames for various amounts of currency which were in common use (much like dime and nickel are used in modern USA).
There was also a value called a guinea which was 21 shillings. This value persists today in auctions, and also in the sale of livestock and race horses.
If you want an idea why the UK moved over to decimal currency imagine trying to work out prices of the following:
As Hunter S. Thompson once said, the great fallacy of the acid culture is the belief that...someone or something is tending the light at the end of the tunnel.
Anything you see on an acid trip, anything you think, is entirely a result of you. You will think about things you normally think about. You will see things you normally see. The difference between an acid trip and normal thought is not that great. It's not a magical chemical that will hook you into the collective unconscious, because if there is one, you're going to have to sober up a little to find it.
Since then, a few individuals here and there have, either from birth or with the assistance of various psychedelics, been able to use these organs at some semblance of their full capacity (I might name William Blake and Jesus as just two), but the onslaught of society has given rise to less and less need for these organs, causing them to degenerate to a point where they're nearly useless without a great deal of help.
There are, of course, other, non-drug-related ways to use these organs, all of which are just as valid. One might hope that through steady and varied use of these methods, some semblance of their previous strength might be attained.
One of the greatest questions about LSD is whether or not it causes hallucinations. While this may seem to be like asking whether rain causes things to be wet, it is not as simple as all that.
The consensus amongst The Merck Manual, alt.drugs.psychedelics and people I have talked to, is that LSD very rarely causes actual hallucinations. While the hallmarks of an acid trip include distortions of space and time, bright colors, and the feeling that inanimate things are moving; actual full on visuals of things that are not there is fairly rare for people who have taken LSD. A rough estimate that I was given on usenet is that less then 5% of LSD trips involve such appearences.
As for what caused LSD, when it was first became popular in the 60's, to be popularly known as a drug that caused hallucinations, the answer may lie in a good amount of media hysteria surrounding it, or in the fact that doses of the drug were much higher at the time, up to 100 micrograms per tab. In any case, unless someone is already mentally ill, or they are taking a lot of very strong, pure LSD, the chances that they will see full visuals of non-existent things is, supposedly, very slim.
Of course, we all know now that a great deal of psychotherapy was inane pseudoscience -- Freud was wrong, and Freud is dead. Their work did show something interesting to modern psychology, though, that there was an extreme difference between response to hallucinogen doses under and over a certain threshold. That is, it's not just our imagination that the giggly, colorful, euphoric, high you get from a hit or two of 'cid is dramatically different from the stunning, deep, potentially overwhelming trip caused by five to ten hits. This schism is also seen with psilocybin, DOM, and the rest, so when I mention LSD from now on, I mean any of the classic hallucinogens.
In the brain, LSD seems to give much of its effect by playing havoc with the serotonin system. Specifically, it is taken up by serotonin neurons and released in a manner no different from normal serotonin. Its effect as a drug comes from its interaction with the 5-HT receptors on other neurons, receptors that are meant to pick up transmissions from the serotonin neuron. LSD fits in the receptors pretty well, but isn't as effective as serotonin -- it produces about 25% of the neural response that a serotonin molecule would. LSD also stays stuck in the receptors longer than serotonin, making those receptors unable to pick up further serotonin neurotransmission.
What makes acid so interesting is that it has a much higher affinity for the receptors; whereas a low concentration of serotonin around a receptor doesn't stand a chance of making it fire, a low concentration of LSD probably will. In other words, not only are neurons that are supposed to be sensitive to a given serotonin neuron fired, a bunch of other, less-related neurons are too. This pseudo-random firing, combined with the receptors' temporary inability to receive further transmission, radically disturbs the brain's normal function, and therefore disturbs the user's consciousness.
So, with low (psycholytic, 50 to 200 micrograms) doses of acid, the transmission is effected more than the reception; the drug works primarily as an agonist on 5-HT receptors. There isn't enough LSD in the system to block all of the receptors, so near-normal neurotransmission can happen, even though a few extra neurons are fired in the process. With a high (psychedelic, 300 to 600 micrograms or more) dosage, the transmission doesn't matter as much because the reception isn't there to pick it up; at this dosage the drug's an antagonist. Receptors pick up all of that ambient LSD until they're all blocked, and any form of normal neurotransmission is shredded, entheogenically removing the person's consciousness from consensus reality.

According to James B. Appel, Professor of Behavioral Pharmacology at USC, LSD causes permanent changes to visual perception in lab rats, and I assume in humans. However, my assumption might be confounded by effective dosage and/or compensatory strategies. Unfortunately, there isn't much scientific research that looks at LSD's pharmacology in humans.
Due to personal experience with LSD and based on my training in cognitive psychology, I hypothesize that LSD disrupts iconic memory, i.e. the visual mode of sensory memory, because, in the widely accepted information-processing system models of cognition, sensory memory is the next stage of processing after sensory input. Iconic memory retains information for between 0.5 and 1.0 second, whereas echoic memory, the auditory mode sensory memory, lasts between 3.0 and 4.0 seconds, just long enough for working memory to grab hold of salient information. In particular, working memory recognizes patterns and feeds distilled information to long term memory where comprehension processes take over (i.e. the lexicon in the case of reading). Regardless of whether attention is the result of bottom-up or top-down phenomena (or both), sensory memory is a constantly renewed copy of low level perception.
Photographic memory occurs when iconic memory is precisely tuned and orderly to the extent that incoming visual stimuli do not rapidly decay. As to what this mechanism must be like, it does not employ afterimages or normal mental imagery. The human visual system is "hard wired" at infancy, and there is no hope for the full recovery of visual perception, as stated earlier. Also, considering that occular dominance columns must develop before a critical age, it is clear that the foundation the visual system does not deal very well with insult. Concerning the gradual extinction of visual tracers, this is probably due to attentional compensation provided through working memory, and is not the result of an increase in available visual information.
After using LSD, the representation of a visual stimulus in iconic memory is no longer governed by precise neuronal firing patterns, but is rather subject to whatever alterations has LSD wrought. LSD is not neurotoxic, yet it does alter synaptic configurations. In the early visual pathway, these changes are not readily reversed. Thus, as goes the early visual pathway, so goes the quality of information in iconic memory. Just as a photograph's detail is limited by the lens, so to is the detail of a memory limited by perceptual fluency. In conclusion, you can kiss your perfect photographic memory good bye forever the first time you take LSD!
LSD is also an abbreviation for Long Slow Distance, a method of running known for its relaxed and gentle approach to training.
The concept originated in the 1920's with Arthur Newton, a British marathoner living in South Africa. Dissatisfied with the training philosphies of his time which stressed fast running over short distances, Newton began running longer and longer distances at a more relaxed pace.
His guidelines for training boiled down to this:
That's it.
Newton had won the 1922 55-mile Comrades Marathon in 8:40. Using his new approach and running roughly 17 miles a day six days a week, he crushed this personal best, breaking the seven-hour barrier in 6:56.
Long slow distance was popularized in 1969 by former Runner's World magazine editor Joe Henderson in his books Long Slow Distance: The Humane Way to Train and The Long Run Solution. (The latter is one of the few books I would enter a burning house to retrieve.)
Henderson maintains that LSD is not so much a training method as it is a way to enjoy running. The easy, stress-free daily run is an end in itself. Hop out of bed, step into running shoes, head out the door for the better part of an hour and feel a gazillion times better, at least fully awake.
As it relates to its chemical namesake, LSD can indeed induce both euphoria and slight hallucinations. I can vouch for this.
On one run in particular along hilly canopy roads in north Florida, I ran with a horse for a few miles, and cool sun showers from the inside of a green breathing stained-glass cathedral washed me of sweat. I left the road and broke some trail, stopping at a clearing overlooking a small lake surrounded by prehistoric trees and thick underbrush. A blue mist rose from everything.
I then noticed that the mist rose also from me. It danced with the constant outward breath of every living thing around me. As I inhaled, I absorbed it. As I exhaled, it absorbed me. The division between me and the universe disappeared. My skin turned to vapor then vanished in a breeze.
Electric and naked, I bounded through fields a thousand yards at a time. Rain fell from leaves like crystal kisses from loving tongues as I broke more trail and found myself back on the road. It took me an hour at a good but effortless pace to get back home, the sun in the trees pouring gold on to puddles.
When I stopped in front of my house, my wife and new baby snoozing inside, I felt as if I had returned from an
