Maryland Law on Safe Storage
Maryland adult-use regulations generally require that cannabis be stored securely and out of reach of anyone under 21. While Maryland does not mandate a specific lock type for home storage of personal-use amounts, the intent of the law — and good practice — is that cannabis is inaccessible to minors and to household visitors who have not consented to access.
Generally described storage practices under Maryland law include:
- Cannabis should remain in its original, labeled, child-resistant packaging or in an equivalent child-resistant container
- Home storage of personal-use quantities (within current per-transaction limits) is legal; larger quantities are not
- Cannabis should not be stored in a way that makes it accessible to minors
Storage Best Practices by Product Type
Cannabis degrades over time due to light, heat, humidity, and oxygen exposure. Proper storage extends freshness and maintains product quality.
| Product Type | Ideal Storage | Key Threats | Shelf Life (unopened) |
|---|---|---|---|
| Flower | Airtight glass jar; cool, dark, dry location (60–70°F, 55–62% relative humidity) | Light, heat, excess humidity (mold), low humidity (dryness, terpene loss) | 6–12 months if stored correctly |
| Pre-rolls | Original airtight tube or case; cool, dark location | Humidity, heat, physical crushing | 3–6 months |
| Vape cartridges | Upright in original packaging; room temperature; away from direct light | Heat (liquefies oil), cold (thickens oil and may clog cartridge), light | 12–18 months |
| Edibles (gummies, chocolates) | Original child-resistant packaging in a cool, dark cabinet or refrigerator (for chocolate) | Heat (melting), humidity, light exposure | Per label; typically 3–12 months |
| Beverages | Sealed, refrigerated after opening; original container | Heat, oxidation after opening | Per label; consume promptly after opening |
| Tinctures | Upright in original dropper bottle; dark, cool cabinet | Light, heat, contamination of dropper | 12–24 months sealed; 3–6 months after opening |
| Concentrates | Original silicone or glass container; cool, dark location or refrigerator for rosin | Heat, light, oxidation, humidity | 6–12 months; varies by type |
| Capsules / tablets | Original child-resistant container; dry, cool, dark cabinet | Moisture, heat | Per label; typically 12–24 months |
Recommended Storage Equipment
A few practical options for compliant, child-resistant home storage:
- Lockable storage boxes: Purpose-built cannabis storage cases with combination or key locks. Many brands are available and specifically designed for this use.
- Locked cabinet or drawer: Any locked furniture that places products out of reach and view.
- Original child-resistant packaging: If undamaged, the packaging your product came in already meets child-resistant standards under Maryland regulations. Keep products in their original containers.
The goal is that a child or a pet cannot independently access the products — a high shelf alone is not sufficient for small children who can climb.
Pet Safety
Cannabis is toxic to dogs and cats. THC poisoning in pets — caused by ingestion of cannabis flower, edibles, or concentrate — causes symptoms including lethargy, incoordination, drooling, vomiting, and in severe cases, seizures or coma. Edibles containing chocolate (toxic to dogs independently) or xylitol (a sugar substitute also toxic to dogs) carry additional risk.
If a pet has ingested cannabis, contact the (888-426-4435) or your veterinarian immediately. Do not wait to see if symptoms worsen.
Traveling With Cannabis in Maryland
Within Maryland, adults 21+ generally may transport legal personal-use amounts in a motor vehicle, subject to the following common guidelines:
- Cannabis should be in sealed, unopened, original packaging
- Opened containers in the passenger area may trigger open container violations; the trunk is generally the safest location
- Consuming cannabis in a vehicle is generally prohibited under Maryland law
Across state lines or on federal property: Cannabis is a Schedule I controlled substance under federal law. Transporting cannabis across state lines or onto federal property (national parks, federal buildings, airports) is generally a federal offense, even between two states where cannabis is legal.
Air travel: TSA screening is federally regulated. Cannabis is not permitted in carry-on or checked luggage regardless of its legal status at the departure or destination. SOL recommends against any air travel with cannabis products.

Disposal
Unused or expired cannabis should be disposed of in a way that prevents access by children, pets, or unauthorized individuals. Options include:
- Drug take-back programs: Some Maryland locations accept cannabis for disposal. Check current availability at cannabis.maryland.gov.
- Home disposal: Mix flower with an undesirable substance (coffee grounds, dirt, cat litter) in a sealed bag before discarding in household trash. Do not flush cannabis down the toilet — it may affect water treatment systems.
- Edibles and liquid products: Dispose in sealed containers mixed with undesirable material in household trash.
