If you’ve just been authorized for medical cannabis, the question almost everyone asks first is some version of: how much am I actually supposed to take? It’s a fair question, and it doesn’t have a tidy answer. Unlike a prescription for an antibiotic, cannabis doesn’t come with a single dose printed on the label that works the same way for everyone. Health Canada’s own guidance is direct about this: there is no precise, standardized dose for legal cannabis products. Each person has to find their own, working with their health care provider through a process called dose titration — starting low, going slow, and adjusting based on how you actually respond.
That sounds vague when you’re new to this. It isn’t, once you understand the framework. This guide walks through what Health Canada currently recommends, what most patients actually use day to day, and how to approach titration methodically instead of guessing.
Why Cannabis Doesn’t Have a One-Size-Fits-All Dose
A few things make cannabis dosing different from most medications. THC and CBD affect people differently depending on body weight, metabolism, prior experience with cannabis, the condition being treated, and even what you’ve eaten that day. Two patients using the identical product for the identical condition can land on very different effective doses — one comfortable at 2.5 mg of THC, another needing several times that before noticing relief.
Health Canada is upfront that this is still an evolving area of medicine. Cannabis products sold in Canada haven’t been reviewed or authorized to treat specific diseases or symptoms, and there’s no official maximum dose established for any condition. What we do have is a consistent, evidence-informed starting framework, and that’s what makes titration workable rather than a shot in the dark.
What Most Patients Actually Use
It helps to know what “normal” looks like before you start. According to Health Canada, most people using cannabis for medical purposes take between 1 and 3 grams of dried cannabis (or its equivalent) per day. Some patients need more, but that’s the exception rather than the rule — and it’s considered highly unusual to use more than 10 grams a day. A meaningful number of patients report benefits at less than a gram daily.
If you’re picturing needing to consume a lot of cannabis to get relief, this is usually a reassuring starting point. Most people land somewhere in a fairly modest range, especially once a dose is properly titrated.
Starting Doses by Method
How you take cannabis changes both how quickly you feel it and how precisely you can dose it. Here’s what Health Canada currently recommends as a starting point for each method.
Oils, tinctures, and other products taken by mouth or under the tongue
This is generally the most precise way to titrate, because doses are measured in milligrams rather than estimated.
- THC: start with 2.5 mg once per day. If you’re over 55, have certain health conditions, or take medications that may interact with cannabis, a more cautious starting point of 1.25 mg is recommended.
- CBD: start with 25 mg per day, which can be split into two doses of 12.5 mg or three of roughly 8.3 mg.
There’s currently no known maximum dose for either cannabinoid — but the pattern holds in both directions: the higher the dose, the more likely you are to notice side effects. If your product comes with an oil dropper, start with one drop. If it’s a metered spray, start with one spray. If it uses a graduated syringe, start with the smallest marked unit. Only increase in that same small increment, and only if you actually need to.
Products taken this way start working in roughly 15 to 40 minutes, peak between 1.5 and 4 hours, and can still be felt for up to 12 hours — which matters when you’re deciding what time of day to take a dose.
Edibles (gummies, capsules, drinks)
Edibles work through the digestive system, so onset is the slowest of any method — typically 30 minutes to 2 hours, with peak effects at 2 to 4 hours and lingering effects for 4 to 8 hours. That delay is exactly why edibles cause more accidental over-consumption than any other format: people don’t feel anything after 45 minutes, assume the dose was too low, take more, and then feel the full effect of both doses at once. The rule here is patience. Take your dose, wait the full window before deciding whether you need more, and never “top up” in the meantime.
Vaping or smoking dried flower
Health Canada doesn’t recommend smoking as a method for medical use — cannabis smoke carries many of the same harmful compounds found in tobacco smoke. Vaping avoids combustion but still carries lung-related risks that aren’t fully understood. That said, both methods act fast: effects begin within seconds to minutes, peak at 10 to 30 minutes, and last roughly 2 to 4 hours. If your care plan involves inhaled flour — our range of BC-grown organic strains includes options suited to different times of day and symptom profiles — start with just one or two inhalations per day and only increase if you’re not experiencing side effects and still need more relief.
Topical, nasal, vaginal, or rectal products
Health Canada notes there currently isn’t enough data to recommend a standard starting dose for these formats. If your care plan includes one of these, dosing should be worked out directly with your health care provider.
THC and CBD Aren’t Interchangeable
A lot of dosing confusion comes down to treating THC and CBD as the same thing measured differently. They’re not. THC is the cannabinoid responsible for the “high” and carries a real risk of impairment, while CBD doesn’t cause intoxication and isn’t associated with addiction. Some patients start their cannabis therapy with CBD-only products before introducing any THC at all, specifically to get a feel for how their body responds without the impairing effects. If your product is a blend of both, check the label carefully — CBD-forward products can still contain meaningful amounts of THC, and that matters for anyone titrating CBD specifically for daytime symptom control.
How to Titrate: A Step-by-Step Approach
- Start at the lowest recommended dose for your product and method.
- Take it in a safe, low-stakes setting — ideally in the evening, at home, with someone else around in case you have an unexpected reaction.
- Wait out the full onset window before judging the effect. This is the step people skip most often, and it’s the one that causes the most accidental over-dosing.
- Only increase if you’re not getting relief and aren’t experiencing side effects. Increase by the smallest available increment — one drop, one spray, the next lowest edible dose.
- Stop increasing the moment you notice side effects, even mild ones like drowsiness or dry mouth. That’s your body telling you where the upper edge of your comfortable range is.
- Keep a simple log. Record the product, the exact dose, the time you took it, what symptom you were treating, how intense it was before and after, and any side effects. This is genuinely the single most useful thing you can do — it turns titration from guesswork into a pattern you and your health care provider can actually read.
- Take it consistently — similar time of day, similar conditions (with or without food) — so you’re comparing like with like as you adjust.
This process can take anywhere from a few days to a few weeks depending on the product and your condition. There’s no prize for rushing it.
A Few Things Worth Knowing Before You Start
- You may still be impaired up to 24 hours later, regardless of method. Don’t drive or operate machinery after taking cannabis, even if you feel “back to normal.”
- Cannabis interacts with a long list of medications and substances — blood thinners, antidepressants, anti-anxiety medications, anti-seizure medications, certain heart medications, sedatives, and alcohol among them. Tell your health care provider everything you’re currently taking, including over-the-counter products and supplements.
- Certain people should avoid cannabis altogether, including anyone who is pregnant, breastfeeding, or planning a pregnancy; anyone under 25 unless a provider has specifically weighed the benefits against the risk to a still-developing brain; and anyone with a personal or family history of psychosis or schizophrenia, or living with significant liver, kidney, or cardiovascular disease.
- Store products securely, in original child-resistant packaging, out of sight and reach of children, teens, and pets.
None of this is meant to be alarming — it’s the same due-diligence conversation your pharmacist would have with you about any new medication. It’s just less familiar territory for most people.
How Much Can You Legally Have on Hand?
Separate from how much you use daily is how much you’re allowed to possess. In Canada, a patient can legally possess up to a 30-day supply of dried cannabis or its equivalent, based on the daily amount your health care provider has authorized — to a hard ceiling of 150 grams, whichever is lower. If your authorization is for 3 grams a day, for example, your legal possession limit is 90 grams (30 × 3g), not the full 150g cap. This is worth understanding early, particularly if you’re deciding how large an order to place at a time.
Matching Format and Product to What You’re Treating
Dosing decisions don’t happen in isolation from what you’re actually trying to manage. Patients using cannabis for chronic pain often lean toward products with a longer duration of action, like oils or edibles, so relief carries through the day rather than needing to be re-dosed every few hours. Patients focused on sleep, mood, or broader mental health support may prioritize consistency and timing over speed of onset. Others — including patients navigating cancer-related symptoms such as nausea or appetite loss — may need a faster-acting option on days when symptoms spike unpredictably.
If flower is part of your plan, strain selection is really just another layer of dosing — different cultivars carry different terpene and cannabinoid profiles that shape the character of the experience alongside the raw THC content. Our current lineup includes Dancehall, Lemon Cherry Pie, Bling Blaow, Frosted Fruit Cake, and Lilac Diesel — each strain guide includes its lab-tested THC and CBD range so you can titrate with real numbers rather than guesswork. If you’d rather explore formats beyond dried flower, our guides to cannabis oil and cannabis extracts cover how those products are typically dosed and absorbed.
It’s also worth reading through the fuller picture of medical cannabis benefits and risks before starting, and if you’re weighing cannabis against a current pain management plan, our comparison of cannabis and opioids for pain may be useful context for that conversation with your provider.
When to Loop In Your Health Care Provider
Titration isn’t a one-time decision — it’s meant to be revisited. Book regular check-ins with your health care provider to talk through whether your current dose is still doing its job, whether side effects have shown up, and whether the product or format still makes sense for you. This matters even more if you’re older, managing multiple health conditions, or taking other medications regularly.
If you’re a Coast Mountain Cannabis client and you’re not sure where to start, our client care team can walk through product options and formats with you — though the specific dose and titration plan should always come from your authorizing health care provider, since they know your full medical picture. All of our flowers are ProCert certified organic, grown without synthetic pesticides or fertilizers, which matters if you’re managing other health conditions and trying to reduce unnecessary exposures on top of what you’re already dealing with.
