There are certain precautions you should take before trying LSD. The
advice below helps to prepare you both physically and mentally. We want you
to be safe and enjoy your experience as much as possible, so if you have a
bad experience or are struggling with especially bad after-effects,
please take note of the advice below.
Every feeling is enhanced with LSD, this is why you want to plan your trip carefully.
Always test your LSD. Other hallucinogens can be sometimes sold as
LSD, many of these other drugs have a smaller safety window (i.e. the ratio of the
typical lethal dose to the effective dose)
Don't try LSD if you are in a bad state and feel a bit down. You
shouldn't take any drug when you are feeling low, but taking psychedelics
is probably the worst idea. You can easily fall into a very
unpleasant rabbit hole.
Try to have a trip-sitter look after you during your trip. Ideally, this
would be someone who remains sober, has had
previous experience with psychedelic drugs, and has read this guide! Or, let someone
you trust know when and where you are planning to take it.
Always take it with other people and, whenever it is possible, with familiar
and kind faces. Experienced users might start trying it out on their own, often to
seek artistic or intellectual inspiration.
Set and setting, i.e. the place you choose to take LSD, is extremely important.
It should be a familiar and safe place. Avoid places that may trigger
negative feelings for you or unsecure and unsafe locations with a lot of people.
If possible, prepare the site beforehand with a friend you trust.
Prepare a music list. Check our section: What should I listen to?
Gather any items you want to experiment with during your trip (books,
videos, pen and paper etc.)
Don't carry valuables while tripping as it's easier to become disoriented
and forgetful. Stay hydrated: bring a bottle of water and some light snacks.
Scientists, writers, doctors and gurus have written a lot about strategies,
ideas and mindsets one should take into account to enhance the experience
beyond the limits of your consciousness. Check the links in
Set and setting

Generally, the LSD experience can be divided into different stages:
Initial effects (come-up)
Slight visual changes, sense of intoxication, uncontrollable need to
laugh, euphoria, anxiety
The peak and plateau
Increase of visuals, time distortion, synaesthesia, loss of the sense of
self, spiritual-experience, suggestibility
Gradual decrease of physical and psychological effects, insomnia
The LSD experience, even when positive, can often be emotionally
and physically draining. Many people like to have a free day after taking
LSD, not to recover from the hangover, but so they can reflect on the
experience as it helps you to gain an even greater
insight from the trip. Know yourself!
You might feel an afterglow for some hours or days or you might feel a bit
off. People vary a lot on their feelings and mood after the trip. If you
avoid a bad trip and get enough sleep, drink plenty of water
and eat a sensible amount of food, you should wake
up in your usual state.
You might still feel that the world looks a bit weird after the trip, so
avoid driving, cycling or doing any risky activities. Wait around 24 hours before doing anything
that requires your full attention and physical coordination.
Just as how LSD can heighten positive feelings, it can also enhance negative feelings.
They can be very
overwhelming and unpleasant. LSD has also been shown to strongly increase
psychotic-like symptoms [Ref Carhart-Harris et al., 2016.]
Even though a bad trip can be absolutely terrifying at the time, it
could lead to beneficial long-term consequences when processed and integrated
properly [Carbonaro et al., 2016]. In
about challenging experiences after taking psilocybin mushrooms, 39% of users who had them said that the experience was
among the top 5 challenging experiences of their lifetime. Despite having
those difficulties, 84% reported having benefited from the experience and
76% reported increased well-being afterwards.
LSD can be very dangerous to people with pre-existing psychotic
illnesses or those who are highly at risk for developing psychosis. Research shows
that LSD makes existing psychotic symptoms worse and can trigger the onset
of the full-blown psychotic episode.
A bad trip can occur when taking a low or medium dose, but the chances
increase with higher doses. Both beginners and experienced users can suffer
a bad trip, so always take the appropriate preventions.
During a bad trip, you might feel:
Unwanted thoughts, emotions and memories
Distressing awareness of physiological processes
Feelings about evil forces/existential crisis
Each person may find their way of escaping a bad trip: listening to a
particular song, talking to a certain person, or looking at a pleasant painting.
We personally recommend lying down in a place without disturbances, close
your eyes and breathe deeply until you feel better.

Helping out a friend
If you are taking care of your friends, keep in mind the following:
Be patient, listen to and observe them
Empathise and express understanding of their fears
Don't try to guide them. Instead, listen to them and talk them through their
experience without imposing your own ideas of what ‘should’ be
Find a more peaceful spot
Tell them that their bad feelings will pass. It can happen and many
people before have suffered it

Accidental overdoses are very rare because LSD has a very high safety window
(the ratio of the typical lethal dose to the effective dose). There isn’t an
exact lethal amount, since it depends on many variables such as the person
and context. Estimates of lethal doses of LSD
are higher than 10 mg (10,000 µg) administered orally, more
than 100 times a normal moderate dose of LSD (100 µg).
Seek immediate medical attention if:
Do not doubt to call a paramedic if you see or feel any of these symptoms. You will
not get into trouble.
There has been only one human incident
where the death has been attributed to LSD
toxicity alone. The quantity of LSD in the blood indicated that 320 mg
(320,000 µg) had been injected intravenously. Very rare LSD-related
fatalities usually result from people committing suicide or accidental deaths.
Understand the trip
In this section The Beckley Foundation
and Drugsand.me provide you with a lot of neuroscientific information.
Let us know what else you want to know about!
A discovery the recent Beckley/Imperial studies have revealed is the shift in the overall connectivity of the brain.
The connectivity within the networks decreases and the connectivity between
the networks increases. The whole brain becomes more integrated, allowing new
functional connections to be formed between brain areas which which normally
do not ‘speak to each other’.
LSD enhances your emotional response to music, increasing wonder,
transcendence, power and tenderness of it. LSD and music
work together to change how your neurons talk to each other, that correlate
with the long lasting change in personality, such as increased openness and
optimism (Lebedev et al., 2016).
LSD intensifies the quality and significance of melodies and lyrics and
affects the perception of the basic musical features such as pitch, tempo and
timbre. LSD and music together
increase the flow of personal memories,
allowing the vivid experience of ‘visions of the past'.
This research by Mendel Kaelen, undertaken as part of the Beckley/Imperial
Research Programme is the first to shed light on how the brain processes
music under LSD, and provide a basis for understanding the therapeutic
effects of music.
What should I listen to?
The powerful influence that music has on your trip can enhance it or make it
really bad, this is why you should pick carefully the music you listen to
while on LSD. There isn't a standardized playlist suitable for everyone.
Follow this advice and adapt it to your taste and the experience you are

Mental time travel refers to the ability to think about future or past, to
recollect aspects of past autobiographical episodes or imagine future
experiences. LSD seems to tune you with the present and it enhances any
stimuli in your environment. This is why the context where you decide to take
LSD is extremely important to ensure you have a good trip and avoid a bad

Suggestibility is the susceptibility or response to suggestion. LSD strongly
enhances suggestibility. This means that the realism or vividness of
suggested situations or scenarios is stronger when you are under LSD.
Why does this matter to you? Again, this is another reason of the importance
of prior expectations (set) and environment (setting) in determining the
nature of your experience. You may want to hide or avoid any object or place
that arises any negative feeling or memory. Similarly, you probably want to
have around things that already calm you down or bring you good vibes in a
Timothy Leary described it as a ‘period of increased reactivity to stimuli,
both from within and without, there is an increase in suggestibility’
(Ref. Leary 1966; Carhart-Harris et.al suggestability paper)
Ego-dissolution is the loss of the sense of 'self' and the feeling of
belongingness to the world.

A visual hallucination
is the vivid perception of an external visual stimulus that does not exist.
Trippers usually see a distortion of what they are seeing. Fractals
(repeated patterns) are a common form of distortion.

is a psychological experience in which two or more senses that are normally
experienced separately are constantly and spontaneously felt together. For
example, the word 'Friday' makes the person to see the colour red. The painter
Kandinsky is a
famous example of a synaesthete (person with these experiences in their daily
LSD triggers synaesthesia-like experiences. This means that even if you are
not a synaesthete you may experience a similar sensation. However, the
experience is different as there is no consistency and specificity in the
pairing of stimulus-sensation. This means that you might suddenly taste the
sweetness of the word 'love' once, but not ever again and you might feel
afterwards how another unrelated word tastes sweet as well. (Ref. Terhune,
2016) In the contrary, a synaesthete constantly tastes sweet when he/she
hears the word 'love' and only this word would trigger the sensation of
sweetness (besides actual sweet food/drink).
Don't be afraid when you see a noise and enjoy the mind-blowing experience!
If you avoid a bad trip, some particular positive
feelings seem to be enhanced the most.
To investigate the effects of LSD on language, done as part of the
Beckley/Imperial Research Programme, a team asked participants to name the
pictures immediately after seeing them. Although the reaction times were the
same as on placebo, study volunteers made more mistakes in naming the
pictures. For example, when shown the picture of a bus, they were more likely
to call it a ‘truck’ or a ‘car’. The mistakes were from the similar semantic
category as the correct answer, but not exactly right. This research explains
how LSD affects semantic networks and the way the brain draws connections
between different words or concepts. "The effects of LSD on language can
result in a cascade of associations that allow quicker access to far way
concepts stored in the mind," said Family.
Psychedelics help to notice associations people wouldn't normally pay
attention to, or help form new connections – this has implications for
enhancing creativity. Ref Family et al., 2016
Pro-social effects of LSD
Under the effects of LSD people report a feeling of belongingness to the
environment, as well as a connection with those who are with them. LSD
changes the way you read people’s expressions and feelings. Consequently,
these are internalised differently and your reaction in social context
differs from your sober state.
To measure the social behavioural changes on LSD, a group of people were
given LSD while they undertook a series of tasks. The scientists aimed to
test some traits that influence our social behaviour such as empathy,
prosociality, emotional response to faces and subjective mood. These were
assessed twice per individual during the ‘trip’ since it lasts for several
hours. Ref Dolder et al., 2016
