Microdosing Basics

Macrodose (Full Dose)

What is a macrodose?

A macrodose is a full psychoactive dose of a psychedelic substance — the amount needed to produce a complete psychedelic experience with significant changes in perception, thought, emotion, and sense of self. This is what most people mean when they talk about "taking psychedelics" or "tripping."

Macrodoses produce effects that are unmistakable and impossible to ignore:

  • Vivid visual and auditory changes
  • Profound shifts in thinking and emotional processing
  • Altered sense of time and space
  • Possible ego dissolution or mystical experiences
  • Duration of 4–12 hours depending on the substance

Macrodose ranges

Substance Macrodose range Duration
Psilocybin mushrooms 2–5 g dried 4–6 hours
LSD 100–200 µg 8–12 hours
Mescaline 200–400 mg 8–12 hours
DMT (smoked) 20–50 mg 15–30 min
Ayahuasca Varies by brew 4–6 hours

Why macrodoses matter for microdosing

Even though microdosing and macrodosing are fundamentally different practices, understanding macrodoses is important for microdosers because:

1. Microdoses are defined relative to macrodoses

A microdose is typically 1/10th to 1/20th of a macrodose. Without knowing the macrodose reference point, you can't properly calibrate a microdose.

2. Macrodose experiences can inform microdosing intentions

Many microdosers have had prior macrodose experiences that revealed insights, patterns, or areas for growth. Microdosing can serve as a way to integrate and sustain the benefits of those larger experiences.

3. Accidental macrodosing is a real risk

Potency variation in natural materials means a dose intended as a microdose can occasionally cross into macrodose territory. Understanding what a macrodose feels like — and having safety strategies in place — is part of responsible harm reduction.

4. Research context

Most clinical research on psychedelics uses macrodoses in therapeutic settings. Understanding the macrodose research helps contextualize the more limited microdosing research.

Macrodosing vs. microdosing: key differences

Microdose Macrodose
Intensity Sub-perceptual Fully psychoactive
Function Normal daily activity Requires dedicated time and space
Duration No noticeable duration 4–12 hours
Frequency Regular schedule (2-4x/week) Occasional (weeks to months apart)
Setting Normal environment Safe, controlled environment
Support Self-directed Trip sitter or therapist recommended
Integration Ongoing, subtle Intensive, post-experience

Safety considerations

If you're a microdoser who accidentally takes too much:

  • Don't panic — the effects are temporary
  • Move to a safe, comfortable environment
  • Contact a trip sitter or trusted person
  • Avoid driving or operating machinery
  • Practice grounding techniques: cold water on wrists, slow breathing, familiar music
  • Remember: no one has ever fatally overdosed on psilocybin or LSD
