## The Short Answer
Cannabis dosing is the single most important skill for adults 21+ new to the regulated market. Get it right and the experience is pleasant and controlled. Get it wrong and you're anxious, paranoid, or sedated for hours longer than you planned. The universal rule: **start low, go slow, and never double up before you've felt the first dose.**
## The Universal Dose Ladder
For adults 21+ with no recent cannabis use, regardless of product format:
| Dose | Expected Experience | Who It's For |
|---|---|---|
| **1–2.5 mg THC** | Subtle, barely perceptible | First-time users, microdosers |
| **2.5–5 mg** | Mild, manageable, entry-level | Most adults for their first dose |
| **5–10 mg** | Clear cannabis experience | Experienced consumers |
| **10–25 mg** | Strong, often sedating | Regular users with tolerance |
| **25 mg+** | Very strong, overconsumption risk | Not recommended without established tolerance |
New York caps adult-use edibles at 10 mg THC per serving and 100 mg per package, a deliberate design choice to keep accidental overdose rarer than in some older markets.
## Format-Specific Dosing
### Edibles
Clearest dose math: THC per serving is printed on the label. Onset 30–90 minutes, peak 2–3 hours, duration 4–8 hours.
**Starting dose:** 2.5 mg. Wait the full two hours before any reassessment.
See our full [edibles guide](/blog/edibles-101-how-they-work-dosing-tips-and-what-to-expect).
### Tinctures (Sublingual)
Each dropper is calibrated. Onset 15–45 minutes, shorter duration than edibles (2–4 hours).
**Starting dose:** 2.5 mg. Hold under the tongue 60 seconds before swallowing.
### Flower (Smoked or Vaped)
Dose is imprecise. Each draw delivers a different amount depending on draw length, flower potency, and individual metabolism.
**Starting dose:** One or two modest draws. Wait 15 minutes before considering more. If you've had none recently, expect effects within 1–5 minutes.
### Vape Cartridges
More consistent than flower because the oil is standardized. Still imprecise compared to edibles.
**Starting dose:** One 2-second draw. Wait 15 minutes.
### Concentrates / Dabs
**Not a beginner category.** THC concentrations of 60–90% mean even a "small" dab is often 25+ mg THC equivalent. Revisit after 3–6 months of regulated experience.
## The Two-Hour Rule
The most common overconsumption pattern in any format, but especially edibles, is taking more because the first dose "isn't working." At 45 minutes into an edible, most people feel nothing. At 90 minutes, they feel a little. At 2 hours, the peak hits.
If you take more at the 45-minute mark, both doses stack and the peak doubles.
**Set a timer. Put the edibles somewhere inconvenient. Don't revisit dose for two hours.**
## Tolerance Matters
With regular use, THC receptors downregulate and effective doses increase, sometimes dramatically. A daily consumer may need 25–50 mg to feel what a new consumer feels at 5 mg.
Tolerance also works the other way. After a tolerance break of 2–4 weeks, receptors upregulate again and previous doses feel much stronger. Adults returning to cannabis after a long break should reset to beginner doses.
See our tolerance break guide.
## Individual Biology Varies
Two adults taking the same 5 mg edible in the same setting can have markedly different experiences. Factors include:
- **Body weight** (loose correlation; not as strong as intuition suggests)
- **Metabolism speed**
- **Digestive state** (food in the stomach slows onset; fatty food improves absorption)
- **THC-metabolizing enzyme variants** (genetic; some adults are fast metabolizers and feel less effect per milligram)
- **Cannabis tolerance history**
- **Medications**, see our drug interactions guide
The implication: **your dose is your dose**. Don't match a friend's intake. Find your own minimum effective dose and work up carefully from there.
## If You Overshoot
A greening-out experience is uncomfortable but not dangerous for a healthy adult. Symptoms: anxiety, paranoia, elevated heart rate, dry mouth, occasional nausea. Protocol:
1. Stay calm. It passes.
2. Hydrate. Eat something light.
3. Lie down in a familiar space.
4. Soft music, comfort TV, a trusted person present if possible.
5. Peak discomfort resolves within 2–4 hours.
6. If you feel alarmed, call a doctor or poison control.

## What Not to Do
- **Don't mix with alcohol** at a first session, combined effects are much stronger and less predictable.
- **Don't drive** at any dose, for at least 4–6 hours (edibles) or 2–3 hours (inhaled).
- **Don't combine multiple formats** at the same session until you know how each affects you alone.
- **Don't take cannabis for a health reason without talking to a doctor**, especially if you take prescription meds.
