LSD or Lysergic Acid Diethylamide (li-ser-jic acid die-ethil-a-myde) also known as acid, tabs and trips was discovered by scientist Albert Hofmann in 1938 and became increasingly popular as a recreational drug in the 1960s. In the past it has been used for treating some psychiatric illnesses as well as alcoholism however it is now an illegal drug.

LSD is a strong psychedelic (trippy) drug. It can alter your senses and thinking, causing colours to appear more vivid and music to sound clearer. It also increases your heart rate and blood pressure. People using it can experience a high, spiritual insight, wakefulness and reduced appetite as well as a feeling of time slowing down, confusion, anxiety and paranoia.

The dosage is dependant on purity and route of administration. An average dose for sublingual administration is around 75?g

(this dose should not be taken as a recommendation). The concentration of LSD on blotter paper may vary considerably

and people taking LSD should be careful with doses and start with a half or quarter. Blots should be halved by cutting diagonally across the paper.

A trip can last from 8-12 hours depending on the dose although users may experience effects (flashbacks) for days, weeks and occasionally years afterwards.

What you need to know

If you choose to take LSD:

Try and buy from a reliable source.
Always use with people you know and trust.
If you find yourself in a bad trip the number one rule is don’t panic. Unpleasant feelings will subside if you don’t focus on them.
Do not drive or operate machinery while on LSD.
Altered perceptions mean you may not spot dangers, so be careful.
If you are in a group have a ‘spotter’ – someone who stays ‘straight’ and knows what to expect from LSD.
People who are experiencing emotional or psychological problems and those who have a family history of mental illness should avoid LSD.
A non-fizzy, sugary drink can be useful for people having a negative experience.
Most people who take trips recommend having a break of a few weeks or months between sessions to allow time process the experience.
There is an increase in the availability of ‘synthetic trips” which may be stronger than LSD so dose low.
