About LSD
LSD is also called:
- dots
- acid
- Buvard
- Window pane
- mellow yellow
- California sunshine
LSD stands for lysergic acid diethylamide. It causes hallucinations and it has very unpredictable effects.
In its pure form, LSD has the appearance of a white crystalline powder, odorless and slightly bitter in taste. On the street, it is often sold in the form of small squares of woody (absorbent) paper soaked in LSD. These squares each contain a dose of LSD and are consumed orally, usually kept on the tongue or swallowed.
LSD can also be sold in powder, capsule or tablet form. The powder can be converted into miniature pellets called “microtips”, which are consumed orally.
LSD crystals can also be dissolved in a liquid. This liquid can be sold in small bottles of breath freshener, or applied to various substances, including:
- candy
- biscuits
- of gum
- postage stamps
- Sugar cubes
- squares of gelatin
People rarely try to inhale or inject LSD.
The SDA is set out in Schedule III of the Controlled Drugs and Substances Act. Activities such as the sale, possession or production of LSD are illegal, unless authorized for medical, scientific or industrial purposes.
Short-term effects of LSD
The effects of the drug are gradually felt from 30 to 60 minutes after consumption and reach their peak after more or less two to four hours. Then the effects fade for a period of 10 to 12 hours. People call their experience under the influence of LSD a “trip.”
The consumption of LSD can lead to mental and physical effects in the short term.
Mental Effects
When you consume LSD, you can see, hear, or feel things that are not really there (hallucinations). LSD affects your brain in:
- changing your senses, moods and thoughts
- distorting your perception of yourself and the world around you
- altering this you hear, taste, feel and feel (more vivid colors, more acute sounds)
- mixing your senses, so that you hear colors and see sounds
LSD produces intense visual effects called pseudo-hallucinations. You know they are not real. The chances that you have hallucinations or do not have hallucinations when consuming LSD are related:
- at the dose of LSD consumed
- Your mood, your thoughts and your environment
Other effects of LSD may include:
- Difficulties of concentration
- impressions of weightlessness or heaviness
- changes or alterations in memory
- The feeling of being disconnected from your body
- extreme mood changes:
- From joy to despair
- from welfare to terror or aggression
- Calm to anxiety or depression
- impaired judgment of distance, time or speed
- the fear of losing control, the fear of death, panic attacks.
Deaths associated with LSD use are usually the result of an accident caused when you experience or see something abnormally. This can lead to errors of judgment. For example, a person may be convinced that they can fly or cross the street unharmed.
Physical Effects
You may also experience physical symptoms like the following:
- Insomnia
- Sweating
- Dizziness
- enlarged pupils (dilated)
- Numbness or tremor
- Less coordination and weakness
- loss of appetite, nausea or drying of the mouth
- Increase or decrease in body temperature
- Increased blood pressure and heart rate
Long-term effects of LSD
The health risks associated with frequent LSD use are more mental than physical. This drug can have long-lasting repercussions on your brain and emotional state. Sometimes the effects continue for years after the consumption of LSD, in particular:
- the paranoia
- Psychosis
- the Depression
- The Returns
Risks related to LSD consumption
If you consume LSD during pregnancy, you increase the risk:
- of spontaneous abortion
- Congenital abnormalities in your infant
You may experience a “bad trip”, especially if you have taken high doses. Bad travel can be scary and understand:
- the paranoia
- A loss of the limits of the self
- A distorted perception of self
Weakened judgment during “bad travel” can result in death or traumatic injury related to risky behaviour.
In some cases, you may experience frequent or excessively intense psychedelic effects. This can lead to sudden reversals that consist in reliving previous experiences.
Backlogs are quite common among hallucinogenic drug users and can cause a lot of stress. If these symptoms persist and disturb you over a long period of time, they are called “persistent post-hallucinatory syndrome.” This disorder is relatively rare.
Another risk of LSD is the psychotic reaction, although it is also rare. Some symptoms of psychosis include the following:
- Delusions
- Hallucinations
- Disorganization of speech
- Disorganized behavior
If you have a predisposition to mental problems or if you already have a mental disorder, there may be a high risk of side effects.
Over the past 10 years, the availability of a large number of new psychoactive substances including LSD-like drugs (analogues) has increased. The harms associated with new drugs are not yet known, but it is clear that these are not without risk.
Disorders related to consumption and withdrawal
LSD does not create physical dependence. Unlike other drugs, people who frequently use LSD are not encouraged to take them. Even if they do not experience physical withdrawal symptoms, some people may develop a psychological dependence on this drug.
If you consume LSD on a regular basis, your body becomes tolerant to its effects. This means that you have to take more and more to feel the same effects. LSD tolerance can develop very quickly.
If you do not stop using LSD for several days, no amount of drug will produce any effect. Sensitivity to the effects of the drug only returns if it is not used for three or four days.
