Navigating the world of medical cannabis can be confusing, especially when it comes to staying compliant with state laws. Whether you’re a first-time patient or just looking to refresh your knowledge, it’s important to understand how Maryland’s medical cannabis laws affect your access, use, and responsibilities.
At CannaLeaf Health, we’re committed to helping you make informed choices about your wellness. Here’s what every medical cannabis patient in Maryland should know about current laws and how to stay compliant.
You Must Be Certified by a Registered Provider
To legally purchase and use medical cannabis in Maryland, you must first register with the Maryland Medical Cannabis Commission (MMCC) and receive a written certification from a licensed provider, like our team at CannaLeaf Health.
What you need to do:
- Register on the Maryland OneStop portal (you’ll receive a patient ID number)
- Schedule an evaluation with a registered provider
- Once approved, visit a licensed dispensary to purchase medical cannabis products
Without a valid certification and MMCC ID, you cannot legally buy or possess medical cannabis in the state.
Legal Age and Minor Access
Adults 18 years old and older can apply for a medical cannabis card. Minors can also qualify but must have a caregiver, such as a parent or legal guardian, who is registered and responsible for purchasing and administering the medication.
Minors also require certifications from two registered providers.
Where You Can and Can’t Use Medical Cannabis
Even with a valid medical cannabis card, usage is restricted to private settings. You cannot use medical cannabis:
- In public places (parks, sidewalks, restaurants)
- While operating a vehicle, machinery, or heavy equipment
- On federal property (including military bases, national parks, and federally subsidized housing)
Violation of these rules could result in legal consequences, even for registered patients.
Possession Limits and Purchasing Rules
Maryland sets clear guidelines on how much medical cannabis a patient can possess:
- Patients may purchase up to 120 grams of dried flower or the equivalent of 36 grams of THC in processed forms (like edibles, tinctures, or vapes) within a 30-day period
- Your dispensary tracks this usage, so exceeding it is not possible unless your provider updates your certification with different limits based on your medical needs
Always carry your MMCC ID card when purchasing or transporting cannabis.
Driving Under the Influence Is Illegal
Even if you’re a certified patient, it’s illegal to drive under the influence of cannabis. If you’re pulled over and found impaired, you could face DUI charges, license suspension, and other penalties—just like with alcohol.
Tip: Always wait several hours after medicating before getting behind the wheel, especially if you’re using THC-dominant products.
Out-of-State Cards Are Not Accepted
Maryland does not recognize out-of-state medical cannabis cards. If you move to or visit Maryland and want legal access, you must register with the MMCC and receive certification from a Maryland provider.
Medical Use Is Still Separate from Adult-Use
Although Maryland legalized adult-use cannabis, medical patients still have distinct advantages, including:
- Access to a wider range of products and potencies
- Lower taxes on purchases
- Guidance from medical professionals
- Personalized dosage and treatment plans
- Shorter lines and reserved hours at dispensaries
