Point your camera at the label. We read the THC, the milligrams and the weight, then tell you what those numbers actually add up to.
Estimates come from a photo and can be wrong. Always check the actual label. Not medical advice.
The app that clears you for good
Clear30 is the #1 science-based weed-break app. Built with clinicians and researchers, used by 150,000+ people — a private, structured 30-day program to reset your relationship with cannabis.
Dispensary packaging is dense with numbers, and most of them are regulatory rather than useful. There are really only four that change how a product will affect you.
The share of the product's weight that is THC. Modern flower usually tests between 15% and 30%. Concentrates and vape carts run from 60% to 90%+, which is why the same lungful is a completely different dose.
Anything eaten or swallowed is dosed in milligrams instead of a percentage, on a “Cannabinoid Facts” panel that works like a nutrition label. The number that matters is milligrams per dose — a 100 mg chocolate bar scored into ten squares is a 10 mg product, but only if you stop at one square.
How much product is in the package: 1 g, 3.5 g (an eighth), 7 g, 28 g (an ounce). This is what turns a percentage into a real quantity of THC.
Listed as a percentage or in milligrams alongside THC. A roughly balanced 1:1 ratio tends to soften some of THC's effects, which is why the scanner lowers its risk read when it sees one.
A gram is 1,000 milligrams. The THC percentage tells you what share of that is THC, so:
Total mg of THC = grams × 1000 × (THC% ÷ 100)
That works out to a simple shortcut: 1 gram of 20% flower is about 200 mg of THC. Put next to the 10 mg standard edible serving, the numbers get striking fast.
| Amount | 15% THC | 20% THC | 25% THC |
|---|---|---|---|
| 0.5 g (a joint) | 75 mg | 100 mg | 125 mg |
| 1 g | 150 mg | 200 mg | 250 mg |
| 3.5 g (an eighth) | 525 mg | 700 mg | 875 mg |
| 28 g (an ounce) | 4,200 mg | 5,600 mg | 7,000 mg |
One caveat worth keeping in mind: that is the THC contained in the material, not the amount that reaches your bloodstream. A large share is destroyed by combustion or exhaled. The number is still the best available way to compare one product against another.
There is no single answer, because tolerance moves the line further than anything else. As a rough map for edibles:
If a dose that used to be plenty now does almost nothing, that is tolerance, not a weaker product — and it is the most common reason people end up taking a break.
Inhaled THC reaches your bloodstream in minutes and peaks in about half an hour, so the feedback loop is immediate — you know quickly whether you have had enough. Eaten THC has to pass through your digestive system and liver first, which takes one to two hours and converts a portion of it into a metabolite that is stronger and lasts longer.
That gap is the whole problem. Nothing happens, so you take another. Then both doses arrive at once, several hours of them. The single most useful rule with any edible is to wait two full hours before deciding it isn't working.
It reads printed numbers well. If the THC percentage, the dosing panel, or the net weight is legible in the photo, it will pull them out and do the arithmetic for you.
It cannot weigh anything. When no weight is printed, it gives a range and labels it a visual estimate rather than inventing a precise figure. You can drag the amount slider to the real number and everything recalculates.
It cannot identify a strain from a bud. If a name appears on the label it will read it and describe what that strain is typically like, framed as a best guess — visual strain identification is not a real thing anyone can do reliably.
It is not a lab. Printed lab values themselves vary between testing facilities. Treat the output as a well-informed approximation, not a measurement.
The photo is resized in your browser, sent once to be read, and then discarded. It is never saved to a database, never attached to an account, and never used for training. There is no signup, no email field, and nothing to delete afterward.
You take a photo of a cannabis product, its label, or its packaging. A vision model reads whatever is printed on it — THC percentage, CBD percentage, milligrams per dose, milligrams per package, net weight, strain and brand — and turns those numbers into a plain-language read on potency, total THC, and how the effects usually play out over time. Nothing you type is required.
A gram is 1,000 milligrams of plant material, and the THC percentage on the label tells you what share of that is THC. So a gram of 20% THC flower contains roughly 200 mg of THC. The formula is grams x 1000 x (THC% / 100). That is the total in the material, not the amount that reaches you — a good deal is lost to combustion and exhalation.
For an edible, 10 mg is the standard single serving in most legal markets, and it is a meaningful dose for someone with little tolerance. Many clinicians and state health departments suggest starting at 2.5 to 5 mg. A regular user may feel very little at 10 mg — tolerance changes the answer more than almost anything else.
No, and the scanner says so. If a net weight is printed on the package it reads that number and marks it as coming from the label. If there is no printed weight it gives a range rather than a single number and flags it as a visual estimate. A photo cannot weigh anything, so we never present an eyeballed amount as exact.
Inhaled THC reaches your bloodstream through your lungs in minutes and peaks within about half an hour. Eaten THC has to pass through your digestive system and liver first, which takes one to two hours and converts some of it into a compound that is stronger and longer-lasting. That delay is why edibles are the easiest way to accidentally take far too much — people redose before the first dose has arrived.
No. The photo is resized in your browser, sent once to be read, and then discarded. It is not saved to a database, not attached to an account, and not used for training. We do not ask for your name, email, or any signup.
No. This is an AI estimate from a photograph, not a lab measurement, and it can be wrong — always check the actual label and follow the product’s own dosing guidance. Nothing here diagnoses or treats anything. If cannabis is affecting your life in ways you do not like, talk to a clinician.
Curiosity about what is actually in your weed is usually the first sign you would like a little more control over it. Clear30 is a science-based 30-day reset built with clinicians and researchers, used by more than 150,000 people, with daily tools, a 24/7 AI coach for cravings, and real human support.
A structured break is the fastest way to find out what cannabis is really doing for you. Clear30 gives you the plan: daily steps, craving tools, human peer support, and a community of 150,000+ people doing the same reset.
