Overview

Educational resource. Last reviewed: June 2026. This article explains Alabama’s regulatory dosage framework for general education. It is not medical advice and does not recommend any dose. Dosing decisions are made by a certifying physician. Program rules can change; verify current requirements with the Alabama Medical Cannabis Commission.

Ask most people what Alabama’s medical cannabis dose limit is, and they will tell you “75 milligrams.” That answer is incomplete in a way that matters. The 75 mg figure is a ceiling reached only under specific conditions – not the everyday limit. The actual framework the Legislature built is a tiered system that starts lower, allows a supervised increase, and carries a striking consequence at its outer edge.

This article explains that framework precisely, using the language of the Compassion Act itself. It is written for patients trying to understand what they can be recommended and for certifying physicians who administer these limits in practice. Throughout, one distinction is essential: this is an article about the legal dosage rules, not a guide to how much any individual should take. The question of an appropriate personal dose is a clinical decision, and nothing here changes that. What follows is a careful walk through each tier of the framework, the exact conditions that unlock each one, and the misconceptions that most often lead patients to misread the law.

What “daily dosage” means

Before the numbers make sense, the unit has to be clear. Under the Compassion Act, a “daily dosage” is the total amount of one or more cannabis derivatives – including cannabidiol (CBD) and tetrahydrocannabinol (THC) – that may be present in a medical cannabis product ingested by a registered qualified patient during a 24-hour period, as determined by a registered certifying physician [1].

Two features of that definition are worth noting. First, “daily dosage” is a per-24-hour concept, not a per-product one; it describes total daily exposure. Second, the physician determines the specific daily dosage for the patient, within the maximums the law sets. So the statutory ceilings discussed below are outer boundaries, and the individualized daily dosage a patient actually receives is set by their physician beneath those boundaries.

The default ceiling: 50 mg of delta-9-THC per day

Here is the fact most summaries omit. The Compassion Act directs the Commission to specify, by product form and THC content, a maximum daily dosage for each qualifying condition – but that maximum “may not exceed 50 mg of delta-9-tetrahydrocannabinol” [2]. Fifty milligrams, not seventy-five, is the baseline ceiling.

This default applies at the start of a patient’s course of care. It reflects the conservative posture of Alabama’s program: begin within a defined, relatively modest limit, keyed to the specific condition and product form, rather than opening at the highest number the statute contemplates. For a patient reading a headline that says “75 mg,” this is the correction that reframes the whole picture – the ordinary starting ceiling is lower.

The first increase: up to 75 mg after 90 days of continuous care

The 75 mg figure enters the framework only as a supervised step-up. Under the Act, a registered certifying physician may increase a patient’s daily dosage if, after 90 days of continuous care under that physician during which the patient was using medical cannabis, the physician determines that a higher daily dosage is medically appropriate. Even then, the increased maximum “may not exceed 75 mg of delta-9-tetrahydrocannabinol” [2].

Three conditions are built into that single sentence, and all must be satisfied:

1. A time requirement: at least 90 days must have passed.
2. A continuity requirement: those 90 days must be continuous care under the physician, during which the patient was using medical cannabis.
3. A clinical-judgment requirement: the physician must determine that a higher daily dosage is medically appropriate.

Only when all three are met may the ceiling rise from 50 mg to as much as 75 mg. This structure keeps dose escalation inside an ongoing physician relationship rather than allowing it on demand, and it is why the “75 mg” answer, given without context, misleads: it is a second-tier maximum, not the standing limit.

The outer edge: terminal illness and the driver’s license consequence

There is one circumstance in which the daily dosage may exceed even 75 mg. Under the Act, a physician may increase a patient’s daily dosage above the ordinary limits if the patient has been diagnosed with a terminal illness. But the statute attaches a specific, consequential condition: if the recommended daily dosage exceeds 75 mg of delta-9-THC, the physician must notify the patient that the patient’s driver’s license will be suspended [2].

This provision is little known and important. It ties a high-dose recommendation for terminal illness directly to driving privileges, and it obligates the physician to deliver that notice. For a patient weighing a higher dose near the end of life, the trade-off is written into the law itself. It is also a vivid illustration of how tightly Alabama couples medical cannabis to public-safety concerns around impaired driving – a theme that recurs throughout the program’s rules.

Minors: a potency limit that functions as a separate constraint

The dosage framework above governs milligrams of THC per day. For patients under 19, a distinct limit applies to potency. A registered certifying physician may not recommend, and a minor may not legally use, medical cannabis with a potency greater than 3% THC – whether or not the minor holds a valid card [3]. The Act extends this further: a parent or legal guardian of a minor cardholder may not legally possess medical cannabis with a potency greater than 3% THC, unless that parent or guardian holds a valid card for their own qualifying condition [3].

Potency (a concentration) and daily dosage (a per-day quantity) are different measures, but for minors they operate together to keep both the strength and the amount within tightly bounded limits. Because the minor pathway carries several such distinctions, it is treated in depth in our dedicated article on medical cannabis for minors in Alabama.

Why the framework is built this way

The tiered structure is not incidental; it encodes the program’s core philosophy. The 50 mg default keeps most patients within a defined limit tied to their condition and product form. The 90-day, continuous-care requirement for any increase ensures that dose escalation happens inside a real, ongoing physician relationship rather than at a single visit. The terminal-illness provision creates a narrow, high-dose pathway while forcing an explicit public-safety trade-off. And the minor potency cap layers an additional protection over the youngest patients. Read together, these rules describe a system designed to keep dosing conservative, supervised, and accountable.

For physicians, the practical upshot is that the maximums are administered through the certification relationship: the physician records the recommended daily dosage and type at certification and revisits it over time, within these statutory bounds. For patients, the upshot is that the “limit” is not a single number to aim for but a supervised range whose top values are gated behind time, continuity, and clinical judgment.

How the physician administers the limits in practice

The statute does not leave dosing to the patient or the dispensary; it routes it through the certifying physician at defined points. At the time of certification, the physician enters into the patient registry the information needed to identify the patient, the qualifying condition or conditions, and the daily dosage and type of medical cannabis recommended [4]. That recommended daily dosage sits beneath the statutory ceiling that applies to the patient’s condition and product form.

A physician certification is valid for a limited period – no longer than 12 months – which builds in a natural point for the physician to reassess [4]. The 90-day continuous-care requirement for any increase then adds a second checkpoint: a physician cannot move a patient to the higher ceiling at a first visit, but must have provided continuous care over that period and formed a judgment that a higher dose is medically appropriate [2]. In effect, the framework distributes dosing decisions across an ongoing relationship rather than concentrating them in a single transaction. This is what distinguishes a certification-based program from a retail one: the milligram ceilings are administered clinically, over time.

Common misconceptions about the limits

Because the dosage rules are widely paraphrased, several misconceptions recur. It is worth addressing them directly.

“The limit is 75 mg.” Only as a second-tier ceiling. The default maximum is 50 mg of delta-9-THC, and 75 mg is reachable only after 90 days of continuous care [2].

“A higher dose is always available for serious conditions.” The terminal-illness pathway does allow doses above 75 mg, but it is narrow and carries an explicit consequence – the driver’s-license-suspension notice – rather than being a general option [2].

“The dose limit tells me how much I should take.” It does not. The ceiling is a legal maximum; the appropriate personal dose within it is a clinical judgment, and it is typically well below the maximum, especially early in care.

“Potency and dose are the same thing.” They are different measures. Potency is a concentration (relevant especially to the 3% cap for minors), while daily dosage is a per-24-hour quantity of THC [1][3].

Clearing up these points matters because each misconception can lead a patient to misread what the law actually permits – and to mistake an outer legal boundary for a personal target.

How this relates to pharmacology

It is worth separating the legal ceilings from the pharmacology of dosing. The statute sets outer boundaries in milligrams of delta-9-THC; it does not tell a patient how their body will respond to a given amount. Because oral cannabinoids are absorbed and metabolized in ways that vary considerably between individuals – and because ingestible onset is delayed – clinicians commonly favor cautious, gradual titration well within these legal maximums. That pharmacological reasoning, including why onset timing matters and why individual responses differ, is covered in our companion article on oral cannabinoid pharmacokinetics. The legal ceiling and the appropriate personal dose are two different things, and the second is always a clinical determination.

Key takeaways

• The default maximum daily dosage in Alabama may not exceed 50 mg of delta-9-THC – not 75 mg [2].
• A physician may raise the ceiling to as much as 75 mg only after 90 days of continuous care during which the patient used medical cannabis, and only if a higher dose is medically appropriate [2].
• For a terminal illness, the dose may exceed 75 mg, but the physician must then notify the patient that their driver’s license will be suspended [2].
• “Daily dosage” is the total THC and other derivatives permitted in a 24-hour period, as determined by the physician [1].
• Minors are limited to cannabis with no more than 3% THC potency, a separate constraint from the milligram ceilings [3].
