Legal LSD session in the Netherlands
In the Netherlands, LSD is illegal because it is on the Opium List as a hard drug with a high degree of danger and addictive properties. LSD is classified as a Schedule 1 drug, meaning it is considered a substance with no medical value and a high risk of abuse and addiction. The possession, production and sale of LSD (and other hard drugs such as cocaine and heroin) is therefore punishable under the Dutch Opium Act. The aim of the law is to protect public health and combat drug crime. According to various studies, LSD may have a medical value and LSD is wrongly placed on list 1 of the Opium Act.
In the Netherlands we can still offer an LSD session in a legal way by not using illegal LSD, but a legal analogue. This legal LSD analogue has exactly the same effect as LSD after ingestion and after conversion by this acidic environment of the body. As a result, the LSD sessions with that legal analogue are also called an LSD session, even though the session does comply with the legislation. According to current legislation, an LSD session is not an official treatment that replaces regular mental health therapy.
Scientific findings
In the past five years, there has been a renewed interest in research into LSD (Lysergic acid diethylamide) and its potential in the treatment of various mental disorders. Old studies from the 1950s and 60s, which had shown that LSD could be a potential therapeutic agent, were abandoned during the war on drugs in the US.
Recent studies have shown that LSD can be used to reduce symptoms of depression, anxiety and addiction. Research is being conducted into LSD's ability to reduce the sense of ego, which can lead to a greater sense of connection with others and the world around us.
A new study has recently been started by the University of Basel, combining LSD with virtual reality therapy to see whether this increases the effectiveness of this treatment. Much is still being discovered about the therapeutic potential of LSD, and more interesting results will undoubtedly be published in the coming years.
How LSD works
With an LSD session, the first noticeable effects start about half an hour after ingestion. The peak of the effects is reached on average after 45 minutes. The effect of LSD can be divided into the subjective experience and the measurable changes in the brain. Read more about the change in brain functioning and the change in perception via the pages below.

The contraindications
According to various studies, LSD is a very safe psychedelic, just like psilocybin. However, combinations with various medications or conditions can be dangerous. It is therefore important to go through an intake process before an LSD session. The intake is a check and can help determine whether you are at increased risk of adverse effects, such as panic attacks, paranoia, hallucinations and other psychological problems. Furthermore, the intake also serves as the basis for personal advice in preparation for a possible LSD session.
- Lithium medication
- Tramadol medication
- MAO inhibitors, SSRI, antidepressants or antipsychotics
- An increased risk of psychosis
- Susceptibility to paranoia
- Susceptibility to suspicion
- High blood pressure or heart problems
