LSD Use: What Is the Lethal Dose of LSD?

LSD Use What Is the Lethal Dose of LSD

So, what is the lethal dose of LSD? The amount that can possibly cause death is unknown, but estimated to be 14,000 micrograms (more than 100 times the normal dosage). This hallucinogen has an exceptionally low toxicity, and it’s highly unlikely that one would ingest a lethal dose even if they had the access to massive dosages LSD. There are also very few case reports of fatalities from taking LSD.

However, it is possible to take a large dose of LSD and suffer severe adverse effects. It’s important to remember that even taking small amounts of LSD can lead to intense and long-lasting psychological effects (up to 12 hours), so it’s always best to start with a very low dose.

Editor’s Note

There have been a few reported LSD overdoses, but there are “miraculous” overdoses, too. One woman took a dose 550 times higher than usual, and survived. It only proves the low LSD toxicity, and supports the thesis that doses are very individual. This is why it’s so important to start slowly. 

Can a Normal Recreational Dosage of LSD Cause a Bad Trip?

Yes, a normal recreational dosage of LSD can cause a very bad trip. The effects of taking too much LSD can range from intense anxiety and fear to suicidal thoughts and violent behavior. It’s important to remember that the effects of LSD are unpredictable, so it’s important to always be careful when dosing with this powerful psychedelic drug.

People can react differently to LSD, and it can be difficult to predict how someone will react, especially if they suffer from mental conditions like bipolar disorder. It’s important to always start with a low dose and gradually increase it until you reach the desired effect. Taking too much LSD can lead to an unpleasant experience, known as a “bad trip.” 

While it’s not a lethal dose of LSD, any dose over 200 micrograms will probably “hit too hard.” Most bad trips happen due to negative external factors, or low mood. But it’s possible that such big of a dose will overwhelm you, which will consequently spark negative emotions, and eventually end in a very unpleasant experience.
