Key Takeaways:

  • LSD is a powerful psychedelic drug that can cause intense hallucinations and drastically alter the perception of reality.
  • It is important to be aware of the potential physical and psychological dangers associated with LSD use, including flashbacks, anxiety, paranoia, psychosis, and dangerous behaviour.
  • Long-term abuse of LSD can result in lasting mental health issues.


LSD, also referred to as acid, is a hallucinogenic drug that is exceptionally powerful and often takes your mind on a wild trip (not always the good kind). 

Much like shrooms, the trip that you experience can vary between something life-changing and something absolutely awful.

But is LSD dangerous?

While LSD has a bad rep among many circles, it is one of the least toxic drugs, and a fatal overdose (while possible) is highly unlikely. There will always be risks, but they are lesser with LSD than with other drugs.

In this guide, we will take you through everything you need to know about LSD, including asking important questions like “is LSD safe?” and “can LSD kill you?”.


What Is LSD (Acid)?

LSD, also known as acid, is a chemical COMPOUND found in ergot fungus. It is commonly used as an illegal recreational drug and is known for its intense effects that produce VIVID sensory experiences, such as hallucinations.

Did You Know: The ergot fungus produces lysergic acid, which is what makes LSD. This is found in grains, such as rye.

The effects of LSD vary from person to person, depending on their mental state and the dosage taken. Generally, the effects are UNPREDICTABLE and range from a pleasant spiritual experience to an overwhelmingly bad trip.

Is LSD Addictive?

No, LSD is not physically addictive. Unlike drugs like opioids and cocaine, there is NO evidence that indicates a physical dependence on LSD [3]. However, tolerance to its effects can occur QUICKLY with frequent use.


How Dangerous is LSD?

So, is acid safe or dangerous? It is IMPORTANT to understand the potential risks [1] associated with taking LSD. Randomized controlled clinical trials have shown it to be SAFE, but there are some risks.

The biggest physical risk is that you can become physically exhausted from the drug’s effects. 

This results from your body being UNABLE to cope with its intense effects for too long. Other physical risks include nausea, headaches, and dizziness.

The biggest psychological risk is that you can have a bad trip, which is an unpleasant experience caused by LSD use. 

It is important to note that ANYONE who takes LSD is at risk of having a bad trip, even if they have taken it before without any problems.


Can You Die From LSD?

While LSD is not considered to be a deadly drug, it is possible to overdose on the drug. However, an LSD overdose is typically characterized by INTENSE physical and psychological effects that can last up to 12 hours.

It is important to note that while an LSD overdose is possible, death is highly unlikely; even if someone takes EXTREMELY high doses of the drug, they would not likely die. 

Despite this, any suspected overdoses should always be treated at a hospital.


Signs of an LSD Oversdose

If someone is experiencing an LSD overdose, they may exhibit the following symptoms:

  • Shallow or irregular breathing
  • High body temperature
  • Agitation or aggression
  • Irregular heartbeat
  • Chest pain
  • Hallucinations or delusions
  • Seizures
  • Loss of consciousness


In cases like this, it is important to call EMERGENCY services immediately and give them a full list of symptoms so that you, or the person you are looking after, can get treatment.


Pro Tip: If you’re worried about police involvement, you do not need to disclose the drug taken over the phone. Just be specific with the symptoms and discuss the LSD with paramedics in person.


Risks and Side-Effects of LSD

It is important to understand that although LSD is not considered to be a deadly drug, it is still very powerful and can have serious consequences [2].


Physical risks of LSD include:

  • Nausea
  • Headaches
  • Blurred vision
  • Dilated pupils
  • Dry mouth
  • Flushed complexion
  • Dizziness
  • Sweating
  • Tremors
  • Loss of appetite
  • Numb/tingling fingers and toes
  • Increased blood pressure
  • Increased heart rate/palpitations


Psychological LSD risks include:

  • Anxiety
  • Depression
  • Euphoria
  • Visual hallucinations
  • Paranoia
  • Panic attacks
  • Synthesis
  • Flashbacks
  • Psychosis
  • Fear
  • Mood swings
  • Intensified senses
  • Feeling detached from your body


Pro Tip: The combination of effects will vary from person to person, and no two experiences are quite the same.


What About the Long-Term Effects of LSD?

LSD, or acid, has been shown to produce long-term effects in some users. This is one of the prevalent LSD dangers that need to be considered before you take it.

Those who take large doses of LSD or have an underlying mental health disorder, such as schizophrenia, are at GREATER risk of experiencing long-term side effects [4]. 

This includes the possibility of becoming stuck on a bad trip with difficulty adjusting to the real world afterwards.

It could also lead to the development of hallucinogen-persisting perception disorder (HPPD), where people experience CONSISTENT hallucinations and other sensations associated with LSD for extended periods.

Lastly, due to the nature of how LSD affects one’s emotional state and mental perspective, it can leave them vulnerable to more serious risks as well, with physical withdrawal symptoms.

A powerful hallucinogenic drug like acid has mind-altering effects that can cause a person to do things they would NEVER consider doing while sober.

For some, this can even lead to AGGRESSIVE or violent behaviour as the intoxicating substances dangerously alter one’s emotional state and sense of reality.

It is clear that under the influence of such dangerous substances, an individual’s judgment can become vastly impaired, and they enter a state of EXTREME emotionality wherein they are unable to manage their reactions or determine appropriate responses.


How to Take Acid Safely and Responsibly

It is important to be aware of the potential risks associated with LSD use and to take steps to reduce these risks.


If you choose to use LSD:

  • Start with a low dose – Always start small and gradually increase your dosage until you find your desired level.
  • Take it in a safe environment – Choose somewhere that is familiar and comfortable. Make sure there is someone else with you who is not using the drug.
  • Know your source – Is acid bad for you? Only when you buy from a dodgy dealer. Only buy LSD from trusted sources and make sure that it is pure.
  • Don’t mix drugs – Avoid mixing LSD with other drugs, including alcohol, as this increases the risk of an adverse reaction. 

By being aware of the risks and taking steps to PREVENT them, you can have a safer and more enjoyable experience with LSD.
