1P-LSD (1-propionyl-lysergic acid diethylamide)

1P-LSD is a novel psychedelic compound that belongs to the lysergamide family, closely related to the well-known hallucinogen LSD (lysergic acid diethylamide). First reported in scientific literature around 2015, it is considered a psychedelic research chemical and is often described as a prodrug of LSD, meaning it may convert into LSD once metabolized in the body.

Users of 1P-LSD report effects that are very similar to LSD, including:

• Altered perception of time and space

• Enhanced colors, patterns, and visual hallucinations

• Intense introspection and changes in thought patterns

• Heightened mood, creativity, and sensory awareness

The effects generally last 8–12 hours, depending on dosage, environment, and personal tolerance. Many in the psychedelic community regard 1P-LSD as slightly less intense and more analytical compared to traditional LSD, though scientific studies are limited.

Since it is a research chemical, the legal status of 1P-LSD varies worldwide. In some regions, it exists in a legal grey area, while in others it may be controlled under analog laws that regulate LSD and its derivatives.

Potential risks include anxiety, confusion, overstimulation, and challenging psychological experiences. As with all psychedelics, set (mindset), setting (environment), and dosage play crucial roles in shaping the experience.
