Key Information





Lysergic Acid Diethylamide


Acid, Trips, Tabs, Flash, Strawberries, Penguins, Microdots.


A ‘trip’ begins after about 1hr and can last anywhere from 2hrs up to 12hrs depending on the strength of the dose and once it starts it can’t be stopped. Strengths vary and it is impossible to know how strong a dose is being taken. The effects vary depending on the strength, the setting and the person’s mood. Hallucinations, changes in sense of time and place and intensified colours are all common effects. Some people experience a ‘bad’ trip, which can make people feel anxious, paranoid and that they are going mad.


LSD is usually found impregnated on small squares of paper with a colourful design. Can also come as tablets. LSD is usually swallowed but it can be absorbed through the pores in the skin.

HEALTH RISKS (long term) which includes withdrawal & tolerance:

LSD can trigger underlying mental disorders. Flashbacks can also occur (when the person relives the trip) which can be extremely frightening. Serious accidents may occur while on a ‘trip’ as hallucinations and paranoia can be very intense, especially for the inexperienced user. There has only been one recorded death worldwide due to overdose, however suicides and accidental deaths are also reported.  Tolerance develops quickly after 3-4 days so that further doses are ineffective. No physical withdrawal symptoms have been reported but users can become psychologically dependent.


LSD is a Class A drug - illegal to have, give away or sell. Possession can get you up to seven years in jail. Supplying someone else, including your friends, with LSD can get you a life sentence and an unlimited fine.

  1. The threshold dosage level needed to cause a psychoactive effect on humans is between 20 and 30 µg (micrograms).
  2. Typical doses in the 1960s ranged from 200 to 1000µg while street samples of the 1970s contained 30 to 300µg. By the 1980s, the amount had reduced to between 100 to 125 µg, lowering more in the 1990s to the 20–80 µg range.
  3. LSD was first synthesized on November 16, 1938 by Swiss chemist Albert Hofmann at the Sandoz Laboratories in Basel, Switzerland.  Its psychedelic properties were unknown until 5 years later,
  4. During the Cold War, intelligence agencies were keenly interested in the possibilities of using LSD for interrogation and mind control, as well as for large-scale social engineering.
  5. LSD is between five to ten thousand times more active than Mescaline.

  7. It has been used experimentally in the treatment of alcoholics and psychiatric patients.
  8. It is often sold as “glue” on the back of stamps and is to be licked off.
  9. LSD is a product of professional chemists. The primary chemical involved, Lysergic Acid, is illegal, so it requires a professional to derive the compound and to turn it into LSD
