The short answer

A cannabis microdose from an edible is roughly 1 to 2.5 mg of THC. That is a fraction of the standard 10 mg serving sold in most legal US markets. Take it once, then wait two full hours before taking any more. Edibles digest slowly, and what you feel at 90 minutes is usually not the peak.

If you have tolerance or use cannabis often, your microdose may sit closer to 5 mg. If you are new, start at 1 mg or less.

What counts as a microdose

  • 0.5 to 1 mg THC: the floor. Most people feel calm or nothing at all. Useful for testing your response.
  • 1 to 2.5 mg THC: the standard microdose. Mild mood lift, easier focus for some, no real impairment for most.
  • 2.5 to 5 mg THC: a low dose, not a true microdose. You will notice it. Fine for a night in, not for a workday until you know your response.

Microdosing means staying under the threshold where you feel high. Where that threshold sits is personal, and it shifts with tolerance, sleep, and what else is in your body.

Why edibles act differently than smoking or vaping

Inhaled THC reaches the bloodstream in minutes. Swallowed THC goes through the stomach and liver, where enzymes convert a large share of it into 11-hydroxy-THC, a metabolite that crosses into the brain more readily. In practice, that means a slower start and a longer, sometimes heavier ride per milligram.

What Is Microdosing Cannabis? Doses, Effects, and How to Start

Typical timing: 30 to 120 minutes to onset, a peak somewhere around 2 to 4 hours, and effects that can linger 6 hours or more. Vape users who try the same number they see on an edible label often overshoot. The number is not transferable.

How to measure a dose from what you bought

  1. Read the label. Find mg THC per serving and per package. Many states cap a package at 100 mg total with 10 mg servings.
  2. Do the math on the piece. A 10 mg gummy cut into quarters gives about 2.5 mg each. Halve one of those quarters for 1.25 mg.
  3. Prefer products that divide cleanly. Gummies and chocolates molded into squares are more consistent than a brownie or a homemade cookie, where THC can clump in one corner.
  4. Use a tincture or oil with a dropper if you want precision. A 30 mL bottle at 300 mg THC holds about 10 mg per mL, so 0.1 mL is 1 mg. Measure with the marked dropper, not a kitchen spoon.
  5. Shake oils and tinctures before each use. Cannabinoids settle over time.

A starting protocol that works

  1. Pick one product and stay with it. Switching products resets the math.
  2. Day one: take 1 mg. Note the time.
  3. Wait two hours. Do not add more because nothing seems to be happening at 45 minutes.
  4. Write down onset, peak, how long it lasted, and how you felt. Rate it 1 to 10.
  5. Next session, no sooner than the following day, adjust by 0.5 to 1 mg. Small steps.
  6. Stop climbing once you reach the effect you want. That is your microdose.

What changes the math

  • Food in your stomach. A fatty meal can slow onset and raise peak intensity.
  • Your liver and metabolism. Two people can take 2 mg and report very different days.
  • CBD content. A 1:1 product feels different from a THC-only gummy at the same THC number.
  • Alcohol and other drugs. Skip the pairing while you calibrate. Ask a pharmacist about interactions with your prescriptions.
  • Tolerance and frequency. Daily use blunts the effect and pushes your number up.

Common mistakes

  • Redosing at 60 minutes because the first dose seems to be doing nothing.
  • Treating a packaged edible and a homemade one as equivalent.
  • Assuming a body weight formula exists. It does not translate well for edibles.
  • Microdosing right before driving or a shift. Even low doses impair some people.

Storing it safely

Keep edibles in the original child-resistant package, labeled, and out of reach of kids and pets. THC poisoning in children is a real and rising reason for emergency visits, and gummies look like candy. Do not decant them into a snack jar. If someone accidentally eats a large dose, call Poison Control.

Legal US markets require 21+ for purchase. That rule exists for a reason, and microdosing does not change it.
