What is LSD?

LSD stands for Lysergic Acid Diethylamide, the most powerful conscious-altering substance known to man.

Made from a fungus called ergot, LSD was first made in 1938 by two chemists from Switzerland, Albert Hofmann and Arthur Stoll. Its hallucinogenic properties were discovered when one of them accidentally ingested some of the drug they had created.

LSD Addiction

Lysergic Acid Diethylamide, commonly known as LSD, is taken by mouth. It has a slightly bitter taste, and is available in tablets, capsules or as a liquid. Acid is commonly sold on a piece of blotter paper, and the user simply chews or swallows it to ingest the drug - without having to buy or conceal any paraphernalia to do so. LSD has zero physical addiction potential. It is not physically addictive and it is not a drug that you will want to immediately do again. This is not the type of drug where a user experiences withdrawal if another dose isn't ingested within a relatively short period of time.

LSD Basics

LSD is a synthetic psychedelic derived from ergot fungus. It is the most powerful conscious-altering substance known to man. Doses of LSD are measured in micrograms (ug) or millionths of a gram. One ounce of LSD contains enough doses for 300,000 adults. Two suitcases of the stuff would be enough to dose the entire population of the USA. LSD is colorless, tasteless and odorless and usually comes soaked into blotters - squares or sheets of paper decorated with kooky designs (sunflowers, strawberries, rockets etc). They cost about $7 per 'tab'. In the 1960s, LSD in small pills (or 'microdots'), gelatin sheets, or in liquid form were common. These forms, however, are extremely rare now.

LSD Drug Tests

Of all the hallucinogens, LSD is the most potent known to man. Taken orally, it takes as little as 25 micrograms or 0.000025 grams of LSD to produce rich and vivid hallucinations in the user. While it is possible to test one’s urine for LSD, the very tiny amounts involved makes detection very difficult. There is also the fact that it is rapidly removed from the body, usually within 24-48 hours.

LSD Effects

The LSD effect is described as a 'trip' because it is a long (8-12 hours) and powerful experience which takes you beyond normal perception and then back again. Simply put, it profoundly alters and expands consciousness by loosening or -- at higher doses -- completely erasing the normal filters and screens between your conscious mind and the outside world.

LSD Legality

In the US, it is categorized under Schedule 1 along with magic mushrooms, cannabis, and heroin. In the UK, LSD is a class A drug.

LSD Mixing

LSD is powerful and unpredictable. As a rule, do not mix with other mind-altering drugs, especially if you are inexperienced or far from home. Please note: there have been very few scientific studies into the effects of combining psychoactive drugs. The information presented here is anecdotal. It is based on the subjective reports of experienced users. Different people will respond differently to different drugs and drug combinations. Know your body. alcohol takes the edge off the effect and can help you to relax; drunkenness disappears during the trip; large amounts increase the nausea; drinking on the comedown is not recommended

LSD Psychedelic Effects

The effects below describe the common physical, mental and emotional effects which comprise the psychedelic experience. This information has been compiled from two sources: the decades of observation and study by psychiatrists in a clinical setting before LSD and other psychedelics were outlawed in the late 1960s; and books and anecdotal trip reports written by users. See here for a list of sources.

LSD Dangers

Scare tactics from the 1960s and 1970s still abound surrounding LSD use. Stories of users who believed they could fly and then died after jumping off multistory buildings still circulate, as well as stories that speak of permanent brain damage or ongoing “flashbacks.” While there may be extremely rare and isolated cases of these dangers, they are not common with LSD use, even higher doses than most users will take. Debunking the rumors is as important as relating the true danger of LSD use to those who seek information about this drug.
