There is no single medical cannabis dosage chart that fits every patient. A dosage chart is a starting reference, not a prescription: it pairs THC and CBD amounts with a route of administration and shows how to move up in small steps. Most clinicians advise beginning at the lowest available dose and increasing slowly until symptoms ease or side effects appear.
Why one chart cannot cover everyone
Cannabis response depends on the person as much as the product. Body weight, liver enzyme activity, prior use, age, and the condition being treated all shift how a given milligram behaves. Two patients can take the same 5 mg THC edible and report completely different experiences. That is why a medical cannabis dosage chart is best read as a range with a titration schedule, not a fixed number to hit.
Medical Cannabis Dosage for Cancer Patients
What a medical cannabis dosage chart usually includes
- Product form: oil, tincture, capsule, edible, flower, vape cartridge, or topical.
- THC per dose: often listed in 1 mg, 2.5 mg, 5 mg, and 10 mg steps, especially for oral products.
- CBD per dose: tracked separately because CBD can change how THC feels.
- THC-to-CBD ratio: rows such as 1:1, 1:4, or 1:20, used to match products to goals.
- Onset and duration: how long until effects start and roughly how long they last.
- Step-up interval: how many days to hold a dose before raising it.
Reading the chart by route
Oral edibles and capsules
Oral products pass through digestion, so onset is slow and effects last longer. Charts typically list the smallest practical starting amount and warn against redosing too soon, since a second serving can stack on the first.
Sublingual tinctures and oils
Held under the tongue, these often begin working sooner than edibles. Many charts give both a starting point and a ceiling to stay under while adjusting.

Inhaled flower and vapor
Effects arrive within minutes, which makes inhalation easier to self-titrate. The tradeoff is a shorter duration, so charts usually describe number of inhalations rather than milligrams.
Topicals
Creams and balms act locally and are generally listed separately, since they are not dosed for systemic effect.
How to titrate using a chart
- Pick the row that matches your product and route.
- Start at the lowest listed amount.
- Keep that dose steady for several days.
- Note symptom relief and any side effects.
- Increase by one small step only if needed.
- Stop at the lowest dose that works.
What changes your effective dose
- Previous cannabis experience and tolerance.
- Whether you ate recently and what you ate.
- Other medications and how they interact.
- Time of day, sleep, and stress levels.
- Product accuracy, since label potency can vary by batch.
Convenience has become part of dosing
Ready-made low-dose formats, pre-measured droppers, and scored gummies make titration easier to follow without guesswork. For many patients, the deciding factor in sticking with a plan is how simple the routine is, not the numbers on the chart alone. A chart you can actually follow beats a precise one you abandon.
When to stop and call a clinician
Contact a healthcare provider if you feel faint, confused, or unusually drowsy, if heart rate or blood pressure concerns you, or if symptoms are getting worse rather than better. Cannabis is not appropriate for everyone, and it can interact with prescription drugs.
Keep a simple dose log
Write down product, route, amount, time, and how you felt two hours later. Patterns show up quickly, and a log gives your clinician real information to adjust the plan instead of guessing from a generic chart.
