How to Dose Cannabis: Edibles, Flower, and Vapes

Getting the dose right is the difference between a great marijuana experience and a bad one. This guide covers how to dose every common product type — edibles, flower, vapes, concentrates, and tinctures — with practical charts and tips from our budtenders at QCD Brooklyn and QCD Staten Island.

Why Dosing Matters

Cannabis affects everyone differently. Your ideal dose depends on your body weight, metabolism, tolerance level, the specific product, and even what you have eaten that day. Taking too little means you might not feel anything. Taking too much — especially with edibles — can lead to anxiety, paranoia, nausea, and an unpleasant few hours.

The good news: cannabis is not lethal in any practical dose. The bad news: an overconsumption experience can be genuinely uncomfortable and can scare people away from cannabis entirely. That is why the golden rule exists.

The Golden Rule: Start Low, Go Slow

Start with the lowest reasonable dose. Wait for the full onset. Then decide if you want more. This applies to every product type, every time, but it is especially critical for edibles, where the delayed onset catches beginners off guard.

Dosing Chart by Method

Method	Beginner Dose	Onset	Duration	Wait Before Redosing
Edibles	2.5–5mg THC	30–90 min	4–8 hours	At least 90 min
Flower (smoking)	1 small puff	1–5 min	1–3 hours	15 min
Vape	1 small puff (2–3 sec)	1–5 min	1–3 hours	15 min
Tincture (sublingual)	2.5–5mg THC	15–45 min	2–4 hours	45 min
Tincture (swallowed)	2.5–5mg THC	30–90 min	4–6 hours	90 min
Concentrates	Not recommended for beginners	Immediate	1–3 hours	15 min

How to Dose Edibles

Edibles are the product type where dosing mistakes happen most often. Because effects take 30 to 90 minutes to appear, new consumers frequently take a second dose before the first one kicks in — and then both doses hit at once.

• Beginner dose: 2.5mg to 5mg of THC. Many gummies and mints at QCD come in precisely dosed 5mg or even 2.5mg pieces.
• Moderate dose: 5mg to 15mg. For people with some experience who know how edibles affect them.
• Experienced dose: 15mg to 30mg+. Only for consumers with established tolerance.

Critical rule: Wait at least 90 minutes before taking more. If you still feel nothing after 2 hours, try another 2.5mg. Your metabolism, body fat percentage, and stomach contents all affect how quickly edibles are processed. Browse our edible selection.

How to Dose Flower and Pre-Rolls

Smoking flower is one of the easiest methods to dose because the effects are felt almost immediately (1 to 5 minutes). You can take a single puff, assess how you feel, and decide whether to continue.

• Take one small puff. Inhale gently — you do not need to take a huge hit.
• Wait 15 minutes. Feel the full effects before taking another puff.
• Repeat as desired. Most beginners find that 1 to 3 puffs is plenty for a session.

THC percentages on flower products range from about 12% to 35%+. For your first time, choose a strain under 20% THC, or ask your budtender for a milder option. Pre-rolls are convenient because they come ready to smoke.

How to Dose Vapes

Vape cartridges and disposable pens deliver concentrated cannabis oil, so each puff tends to be more potent than a puff of flower. The onset is similar (1 to 5 minutes), but the effects per puff are typically stronger.

• Take one short puff (2 to 3 seconds).
• Wait 15 minutes.
• Assess and repeat. Vapes make it easy to take small, controlled doses.

Look for vape products that list their THC percentage. Lower-THC or balanced THC:CBD cartridges are good starting points. Read more about THC vs CBD ratios in our THC vs CBD guide.

How to Dose Concentrates

Concentrates are not recommended for beginners. Products like wax, shatter, live resin, and budder typically contain 60% to 90% THC — several times more potent than flower. Even a tiny amount can produce intense effects.

If you are an experienced consumer interested in concentrates, start with a “rice grain” sized amount and wait 15 minutes. Dabbing requires specific equipment and technique — ask a QCD budtender for guidance.

How to Dose Tinctures

Tinctures come with measured droppers, making them one of the most precise dosing methods available. How you take a tincture affects onset time:

• Sublingual (under the tongue): Hold the oil under your tongue for 60 seconds before swallowing. Onset in 15 to 45 minutes. This is faster because the cannabinoids absorb directly into your bloodstream through the tissue under your tongue.
• Swallowed: If you swallow the tincture directly or mix it into food/drink, it acts more like an edible. Onset in 30 to 90 minutes.

Start with the lowest dose marked on the dropper (often 0.25ml to 0.5ml) and check the product label for the THC content per serving.

Microdosing

Microdosing means taking very small amounts of THC — typically 1mg to 2.5mg — to achieve subtle effects without a noticeable high. People microdose for mild relaxation, focus, creativity, or low-level pain management throughout the day.

Microdosing works best with precisely dosed products like low-dose edibles (many brands make 2.5mg gummies), tinctures, or beverages. It is a good strategy for people who want the benefits of marijuana without impairment. Learn more about cannabinoid options in our Cannabis 101 guide.

Tolerance and When to Stop

With regular marijuana use, your body builds tolerance — meaning you need more to achieve the same effects. This is normal and not dangerous, but it is worth being aware of. If you find your usual dose is not working as well:

• Take a tolerance break (T-break). Even 2 to 3 days without cannabis can noticeably reduce tolerance. A week or more will reset it significantly.
• Rotate products. Switching between strains, consumption methods, or cannabinoid ratios can help.
• Do not just keep increasing your dose. Higher doses mean higher costs and increased risk of side effects.

When to stop during a session: If you feel comfortable and pleasant, you are at a good dose. If you feel any anxiety, discomfort, or dizziness, stop consuming and wait. Drink water, find a comfortable spot, and breathe. The effects are temporary.

Frequently Asked Questions

How many mg of THC should a beginner take?

Beginners should start with 2.5mg to 5mg of THC, especially with edibles. This is considered a low dose and is enough to feel mild effects without being overwhelming. Wait at least 90 minutes before taking more, as edibles take time to kick in.

How long do edibles take to kick in?

Edibles typically take 30 to 90 minutes to produce noticeable effects, depending on your metabolism, what you have eaten, and the product formulation. Some people may not feel effects for up to 2 hours. Never take a second dose before waiting at least 90 minutes.

What happens if I take too much marijuana?

Taking too much THC can cause anxiety, paranoia, rapid heart rate, nausea, dizziness, and disorientation. While uncomfortable, these effects are temporary and not life-threatening. If it happens, find a calm space, drink water, eat a light snack, and wait. Effects will subside within a few hours.

What is microdosing marijuana?

Microdosing means taking very small amounts of THC, typically 1mg to 2.5mg, to get subtle therapeutic benefits without a noticeable high. People microdose for focus, mild relaxation, creativity, or low-level pain management throughout the day.

How do I dose flower or a pre-roll?

Take one small puff and wait 15 minutes before taking another. The effects of smoking flower are felt within 1 to 5 minutes, so you will know relatively quickly how it affects you. This is easier to control than edibles because the onset is fast and you can stop at any point.
