We invited five Florida-licensed physicians — three internal medicine, one psychiatrist, one palliative care — to the same table for one long afternoon. The brief was simple: talk about moderation. What it means in a medical cannabis context. Where the line is. How to coach patients who haven't found it yet. The conversation ran three and a half hours; what follows is roughly half of it, edited for length and clarity.
None of the physicians quoted below would let us use their names — they treat patients in a regulated program and didn't want their case recommendations attributed. We've identified them by specialty and a number, so you can follow the threads. Their composite credentials: 78 years of combined practice, 4,400 medical cannabis certifications, and one shared frustration with how rarely the moderation conversation gets had in public.
On the basic question
Q: Let's start at the bottom. Is there a "right" amount of medical cannabis to use?
Internal Medicine 1: The honest answer is no. "Right" depends on what we're treating, how the patient responds, what other medications they're on, and what they're trying to do with their day. The right dose for a chronic-pain patient is going to be very different from the right dose for someone using it for sleep, and very different again from someone using it for anxiety.
Psychiatrist: But there's a more useful question hiding under that one, which is: what's the least amount of cannabis that gets the clinical job done? That's the question I try to make my patients ask themselves. The whole frame shifts when you go from "how much can I use?" to "how little do I need?"
On daily use
Q: Most of your patients use cannabis daily. Is daily use inherently a problem?
Palliative: No. I have patients who use cannabis daily for the same reason they take their other medications daily. The indication is real, the dose is steady, and the benefit is clear. We should be careful not to pathologize daily use just because it's cannabis.
Internal Medicine 2: Agreed. The flag isn't frequency, it's escalation. If you're using the same amount you were six months ago and getting the same benefit, that's a stable medication regimen. If you're using twice as much for the same benefit, that's tolerance, and we need to talk about it.
Internal Medicine 1: The other flag is function. Is the patient still doing the things they previously valued? Still showing up at work, still maintaining relationships, still getting outside? If yes, daily is fine. If no, we have a different conversation, irrespective of dose.
"The flag isn't frequency. It's escalation, and it's function."

On tolerance
Q: Walk me through how tolerance builds.
Psychiatrist: The CB1 receptor — the main receptor THC binds to — downregulates with sustained use. You need more to get the same effect. This happens within weeks of regular dosing for most patients, and faster at higher doses.
Internal Medicine 1: The clinical implication of that is patients often don't realize they've crossed from "this is helping me" into "this is keeping me from feeling worse than I'd feel without it." Those are very different states. The first is medication. The second is closer to dependence.
On the tolerance break
Q: Talk to me about tolerance breaks. How long, how often, do they actually work?
Internal Medicine 2: They work, and the science is clearer here than people realize. CB1 receptors begin to upregulate within 48 hours. Most patients report meaningfully restored sensitivity at the seven-to-fourteen-day mark. A three-week break gets you closer to baseline.
Palliative: I recommend most of my non-acute patients take one one-week break per quarter. Not because I think daily use is bad, but because it gives both me and the patient a clean look at how much benefit the medication is actually producing. Sometimes a patient comes off for a week and says, "I'm honestly not sure I needed the last six months of this." That's useful information.
Psychiatrist: The thing nobody warns you about with tolerance breaks is that the first three to four days are unpleasant. Sleep gets worse. Appetite drops. There's an irritability piece. None of this is dangerous, but you should plan around it. Don't do it during a stressful work week.
On the question of dependence
Q: Can you become dependent on medical cannabis?
Internal Medicine 1: Yes, in the clinical sense. Cannabis Use Disorder is in the DSM. The numbers vary by study, but somewhere around nine percent of adult users will develop it at some point. Higher in patients who started young, higher in heavy daily users, higher with high-THC products.
Psychiatrist: But it's important to keep "dependence" in proportion. The withdrawal syndrome is real but it's not severe in the way alcohol or benzodiazepine withdrawal is severe. You will not die from cannabis withdrawal. You will be irritable and sleep badly for a week. That distinction matters.
Internal Medicine 2: The other distinction is physical dependence versus addiction. A patient on a long-term opioid regimen for cancer pain is physically dependent — they'd have withdrawal symptoms if you stopped abruptly — but they are not necessarily addicted. Same is true for cannabis. The two can occur together; they often don't.
On format
Q: Does it matter whether someone is using flower, edibles, tinctures, or something else?
Internal Medicine 2: A lot. Inhalation produces fast onset and short duration — that's actually protective against escalation, because you feel the effect quickly enough to know you can stop. Edibles produce slow onset and long duration. Patients escalate edibles all the time because the first dose hasn't kicked in yet.
Palliative: Tinctures are the most underrated format. Precise dosing, predictable onset window, longer duration than inhalation but shorter than edibles. For patients struggling with moderation, I often switch them from flower to tinctures and the problem solves itself.
On the dose ceiling question
Q: Is there a maximum daily dose you'd flag?
Internal Medicine 1: I get this question a lot and I try not to give a single number, because the question is wrong. The question isn't "what's the max?" — it's "what's the effective dose?" The lowest dose that gets the clinical job done. For most of my patients, that's somewhere between five and twenty milligrams of THC per day.
Psychiatrist: If a patient tells me they're using more than fifty milligrams a day, I want to have an explicit conversation about whether the dose is still producing benefit or whether we've crossed into tolerance-driven use. That's not a moral judgment, it's a medication-management question. Same conversation I'd have with a patient on any other long-term medication.
On knowing when to stop
Q: How do you advise a patient who suspects they're using too much?
Palliative: The first thing I say is: come talk to me. Not because I have a magic answer, but because the conversation itself often clarifies what's going on. Patients are usually right when they suspect this; they just haven't said it out loud yet.
Internal Medicine 1: The second thing is that the structured taper is real, and effective. We bring the dose down slowly over a few weeks, switch to a more controllable format if needed, and add a tolerance break at the end. Most patients are surprised by how manageable it is when they actually plan it, versus trying to white-knuckle it.
Internal Medicine 2: The third thing — and this is the one nobody wants to hear — is that for some patients, the right answer is to stop entirely. Not most patients. But some. And our job is to help with that as actively as we help with certification.
On what they wish patients knew
Q: One last question. What do you wish every new patient walked into your office knowing?
Psychiatrist: That low doses do more than they think. The marketing in this industry skews toward "more THC is more value," and that's wrong. Two and a half milligrams is a legitimate dose. A lot of patients should never go above ten.
Internal Medicine 2: That this is medicine. Not a recreational product they happen to be getting through a clinic. The same rules that apply to other medications — track what you take, notice the effect, talk to your physician — apply here.
Internal Medicine 1: That the entire program works best when patients participate in their own care. Tell us when something's working. Tell us when something isn't. The program is flexible. We can adjust.
Palliative: That moderation is not abstinence. The goal isn't zero use. The goal is the dose that makes your life work, no more.
Internal Medicine 2: And — last thing — that this isn't a conversation that has to happen once. It happens at every visit. The right dose this year may not be the right dose next year. That's normal.
We talked for another forty minutes after that. The dishes came; coffee was offered; the door was opened to let some air in. By the time we left, the room had emptied around us. Two of the physicians were heading back to clinic. Three were going home. The conversation, they all agreed, was the kind they wished they had time for in their offices, between certifications. Maybe more of it would help.
