LSD is approximately 200 times as potent as psilocybin and 5,000 times as potent as mescaline, meaning that it produces effects of similar magnitude at 1/200 and 1/5,000 times the respective doses. LSD is an extraordinarily potent substance, and is one of the most potent psychoactive drugs known. LSD is extremely potent, with noticeable effects at doses as low as 20 micrograms and is sometimes taken in even smaller amounts for microdosing. Lysergic acid diethylamide, commonly known as liquid lsd LSD (from German Lysergsäurediethylamid) and by the nicknames acid and lucy, is a semisynthetic hallucinogenic drug derived from ergot, known for its powerful psychological effects and serotonergic activity. Like all illicit drugs, LSD use poses potential physical and mental health risk

In the United Kingdom, Michael Hollingshead, liquid lsd reputed for introducing LSD to various artists and musicians like Storm Thorgerson, Donovan, Keith Richards, and members of the Beatles, played a significant role in the drug's proliferation in the British art and music scene. San Francisco-based artists such as Rick Griffin, Victor Moscoso, and Wes Wilson contributed to this movement through their psychedelic poster and album art. The last FDA approved study of LSD in patients ended in 1980, while a study in healthy volunteers was made in the late 1980s. Several figures, including Aldous Huxley, Timothy Leary, and Al Hubbard, had begun to advocate the consumption of LSD as it became central to the counterculture of the 1960s. In 1963, the Sandoz patents on LSD expired and the Czech company Spofa began to produce the substance. It was listed as a Schedule I controlled substance by the United Nations in 1971 and currently has no approved medical use
Presumed or known prodrugs of LSD, including 1A-LSD (ALD-52), 1P-LSD, and 1V-LSD, have been developed or encountered. However, detecting LSD in human tissues is more challenging due to its active dose being significantly lower (in micrograms) compared to most other drugs (in milligrams). The acute effects of LSD normally last between 6 and 12 hours depending on dose, tolerance, and age. However, it was found to have profoundly reduced activity at the serotonin 5-HT2 receptors relative to LSD in vitro. In an earlier 2016 study, intravenous LSD effects similarly peaked after about 1.7 hours. However, in the 2025 study, time to maximal effects was about 2.5 hours orally and about 1.2 hours intravenousl
How the drug works varies from person to person Experimental studies attempted to measure the effect of LSD on creative activity and aesthetic appreciation. It has been used as a treatment for cluster headaches with positive results in some small studies. A 2020 meta-review indicated possible positive effects of LSD in reducing psychiatric symptoms, mainly in cases of alcoholism. New clinical LSD experiments in humans started in 2009 for the first time in 35 years. By the 1960s however, controversies surrounding "hippie" counterculture began to deplete institutional support for continued studies.
The median lethal dose (LD50) of LSD in animals varies and is 50 to 60 mg/kg in mice, 16.5 mg/kg in rats, and 0.3 mg/kg in rabbits all given by injection. There is a case report of severe neurological sequelae following a single typical recreational dose of LSD involving seizure and cardiorespiratory arrest. Common adverse effects (2.4–42%) included agitation or irritability, tachycardia, hallucinations or delusions, confusion, pupil dilation, hypertension, drowsiness or lethargy, elevated creatine phosphokinase (CPK), nausea and vomiting, and others. In other reports, a 5 mg overdose of LSD produced severe nausea and vomiting along with severe behavioral disturbances, while a 10 mg overdose was also non-fatal.
What if I use other drugs with LSD?
The DEA performed a chromatographic analysis of blotter paper containing 2C-C which showed that the liquid lsd paper contained a much greater concentration of the active chemical than typical LSD doses, although the exact quantity was not determined. While it is true that LSD requires lower doses than most other hallucinogens, blotter paper is capable of absorbing a much larger amount of material. Many street users of LSD are often under the impression that blotter paper which is actively hallucinogenic can only be LSD because that is the only chemical with low enough doses to fit on a small square of blotter paper. Many mimics are toxic in comparatively small doses, or have extremely different safety profiles.
How does it make people behave?
Negative experiences, commonly known as "bad trips", can induce feelings of fear, agitation, anxiety, panic, and paranoia. Positive experiences, or "good trips", are described as intensely pleasurable and can include feelings of joy, euphoria, an increased appreciation for life, decreased anxiety, a sense of spiritual enlightenment, and a feeling of interconnectedness with the universe. The primary immediate psychological effects of LSD are visual pseudo-hallucinations and altered thought, often referred to as "trips". By the 1980s, the amount had reduced to between 100 and 125 μg, dropping more in the 1990s to the 20 to 80 μg range, and even further in the 2000s. In the mid-1960s, Owsley Stanley, the most important black market LSD manufacturer in the United States, distributed LSD at a standard concentration of 270 μg, while street samples of the 1970s contained 30 to 300 μ
