Dosing Cannabis Edibles + Vapes: A Practical Guide
How cannabis dosing actually works for edibles, vapes, and pre-rolls. Onset, peak, duration, milligram math, and how to avoid the most common dosing mistakes.
The most common mistake we see at Firestorm is a customer eating a 10mg edible, feeling nothing after 45 minutes, eating another 10mg, then having a rough three hours when both kick in at once. Cannabis dosing has rules — they're not strict, but ignoring them leads to predictable bad experiences. This guide is the practical version: start dose for first-timers, how onset works for each format, why edibles feel different from inhaled products, and how to read a Maine OCP label so you actually know what you're buying. We base these recommendations on standard Maine adult-use packaging (10mg per piece, 100mg per package) and on the timing guidance published by NIDA and confirmed by our own lab work.
- 01
First edible dose: 2.5–5 mg THC
Cut a 10mg gummy in half. Eat with food, hydrate, and wait the full 90 minutes before considering more. If 5mg felt like nothing, take another 5mg next session — not the same session.
- 02
First vape dose: a single 3-second puff
Inhale a 3-second puff, hold 2 seconds, exhale. Wait 10 minutes. If you want more, take a second puff. Vape effects build over the first 10–15 minutes.
- 03
First pre-roll dose: 1–2 puffs of a 0.5g joint
Same 10-minute wait between puffs. A 1g joint is rarely a single-session dose for a new consumer — share it or save half.
- 04
Re-dose protocol: wait the full onset window
Edibles: 90 minutes. Vapes: 15 minutes. Flower: 15 minutes. Re-dose stacking is the #1 cause of bad experiences. Patience is the dose-control mechanism.
Edibles onset: why it takes 90 minutes
When you eat THC, it has to pass through your digestive tract to your liver. The liver converts THC into 11-hydroxy-THC — a metabolite roughly 1.5–3× more potent than inhaled THC for the same dose. This process takes 30 to 90 minutes depending on what you ate, your metabolism, and the edible's formulation.
Effects peak around the 2-hour mark and last 4 to 6+ hours. This long tail is the reason edibles work well for sleep and chronic-discomfort use cases — and the reason they're tricky for first-timers expecting an immediate result.
Inhaled cannabis: seconds to minutes
Smoking flower or vaping a cartridge delivers THC directly to your bloodstream via the lung's alveoli, bypassing the liver. Effects peak within 10 to 30 minutes and taper over 1 to 3 hours.
This makes inhaled cannabis the most dose-controllable format for new users: you can take a single puff, wait, and decide if you want more. Edibles offer no such re-dose flexibility within the first 90 minutes.
We dose from our own distillate, by mass, every batch tested. 10mg means 10mg. If you took 10mg and felt nothing, it's not the gummy — it's the clock.
Reading a Maine OCP label
Every adult-use product in Maine must list: total THC per package, total THC per serving, batch number, harvest or production date, and an OCP child-resistant tamper-evident seal. A '100mg gummy pack' means 10 × 10mg pieces.
Pay attention to the per-serving line, not the package total. A 200mg bag is 10 × 20mg pieces — twice the per-piece dose. New users should default to the 100mg / 10mg-per-piece formulation.
What if I overshot?
Cannabis is not lethally toxic, but overshooting THC dose is unpleasant and can produce racing thoughts, elevated heart rate, nausea, and acute anxiety. The condition is self-limiting — it passes as the body metabolizes the dose.
Hydrate. Eat starchy carbs. Find a low-stimulation room. CBD-dominant products (1:1 or 4:1 CBD:THC) taken alongside can blunt THC overactivation. Sleep usually resets the system within 4–8 hours.
If symptoms are severe or you have a heart condition, call 911 or your physician. This is rare but not unheard of.

Questions answered.
01How long until an edible kicks in?
How long until an edible kicks in?
30 to 90 minutes for most people. Effects peak around 2 hours and last 4 to 6+ hours. Wait the full 90 minutes before re-dosing.02What's a low first dose?
What's a low first dose?
2.5 mg or 5 mg of THC. Most Maine gummies come in 10mg pieces — start with half a piece.03Why do edibles hit harder than vapes?
Why do edibles hit harder than vapes?
Edibles are metabolized in the liver to 11-hydroxy-THC, which is 1.5 to 3× more potent than inhaled THC at the same dose.04Can I sober up faster?
Can I sober up faster?
Not meaningfully. Hydration, food, and rest help symptoms. Sleep resets baseline. CBD can blunt acute THC overactivation when taken concurrently or shortly after.
