Can You Die from LSD?
LSD Toxicity and Fatal Poisoning
LSD (lysergic acid diethylamide) is generally considered non-toxic and medically safe when taken at standard dosages (50-200 µg)2. However, there have been rare instances of fatal poisoning associated with LSD. The first reported case of fatal poisoning by LSD involved the detection and measurement of LSD in ante-mortem serum, plasma, and post-mortem blood, liver blood, and stomach contents1. These cases are extremely rare and often involve massive overdoses or other complicating factors.
Psychological and Physiological Risks
LSD is known to cause significant psychological disturbances, such as "bad trips," which can lead to accidental deaths or suicides, particularly when the drug is taken under suboptimal conditions2. While the drug itself is not typically lethal, the psychological effects can lead to dangerous behaviors, such as attempting to fly from a building5. Additionally, some fatalities have been associated with extreme physical restraint or hyperthermia caused by substances mistaken for LSD2.
Safety and Tolerability in Controlled Settings
Studies have shown that LSD is generally safe and well-tolerated in controlled settings. For example, a study involving healthy adults administered doses of 50, 75, and 100 µg found no serious adverse events, with only mild adverse events reported4. Another study on older adults using low doses (5, 10, and 20 µg) also reported good tolerability and no significant adverse effects6. These findings suggest that, under controlled conditions, LSD can be administered safely.
High-Dose Risks and Adverse Effects
While standard doses of LSD are generally safe, higher doses can lead to more severe physiological and psychological effects. A pooled analysis of studies involving doses up to 200 µg found that higher doses increased the likelihood of both positive and negative subjective effects, as well as physiological responses like increased heart rate and body temperature8. However, even at these higher doses, the physiological effects were moderate and did not result in severe harm in a controlled research setting8.
Conclusion
In summary, while LSD is generally non-toxic and safe at standard dosages, there are rare instances where it can be fatal, particularly in cases of massive overdose or when combined with other risk factors. The psychological effects of LSD can also lead to dangerous behaviors that may result in accidental death. However, in controlled settings, LSD has been shown to be safe and well-tolerated, even at higher doses. It is crucial to understand the context and conditions under which LSD is used to accurately assess its risks.

Case ReportIs LSD toxic?
LSD is non-toxic and medically safe when taken at standard dosages (50-200g), and the true causes of fatalities attributed to LSD toxicity include massive overdoses, excessive physical restraints, and psychoactive drugs other than LSD.
The mutagenic effect of lysergic acid diethylamide. II. Dominant lethal test in mice.
LSD induces dominant lethals in both male and female mice, with the frequency of dominant lethals depending on the dose applied and the stage of spermatogenesis.

Animal StudySafety, tolerability, pharmacokinetics, and subjective effects of 50, 75, and 100 µg LSD in healthy participants within a novel intervention paradigm: A proof-of-concept study
50, 75, and 100 g LSD are tolerable with favourable safety profiles in healthy adults, causing mild adverse events and mystical-type subjective experiences.

Meta-AnalysisVery Rigorous JournalAlterations of consciousness and mystical-type experiences after acute LSD in humans
Mystical-type experiences are infrequent after LSD, with greater or different alterations of consciousness at 200 g dose compared to 100 g dose, and ego dissolution may reflect plasma levels of LSD, rather than robustly induced effects.
