Maryland’s allotment calculation is a hybrid of product category conversion ratios and THC-based calculations for concentrates, enforced through the METRC integration. Dutchie must use lab result THC values for concentrates and apply the correct conversion factors to ensure compliance and accurate tracking of patient allotments. Here’s a comprehensive breakdown of how Maryland allotment data is calculated:
Things to know
- Maryland uses METRC for tracking cannabis sales and patient allotments.
- There is a special "Maryland Allotment Check" setting in METRC-integrated systems (like Dutchie POS) that must be enabled to apply Maryland’s unique calculation logic.
- This logic uses lab results for concentrates and specific conversion ratios for different product types.
Product Category Conversion Ratios
Maryland defines conversion ratios to translate non-flower products into "flower equivalents" for allotment tracking:
-
Edibles:
- 100mg of edibles = 5.67g flower
- 10mg of edibles = 0.567g flower
-
Concentrates (including vapes):
- 1g of concentrate (vape) = 3.54g flower
- 0.5g of concentrate (vape) = 1.77g flower

THC-Based Calculation for Concentrates
For concentrates, the calculation is based on the THC content as reported in the lab results, not just the product weight. The system multiplies the THC content (in grams) by a conversion factor (typically 3.33) to determine the flower equivalent.
- Example: If a package has 400mg THC (0.4g), the flower equivalent is 0.4g × 3.33 = 1.33g flower.
Allotment Limits
- Medical Patients: Can purchase up to 120g of dried flower or 36g of THC product per month, or a combination (using flower equivalency).
- Recreational Customers: Limits are set per category (e.g., 42g flower/day, 12g concentrates/day), but flower equivalency is not always used for rec purchases.
System Enforcement
- The POS system checks the patient’s remaining allotment in real-time via METRC before completing a sale.
- The system uses the lab result THC value for concentrates and the product weight for flower.
- The calculated flower equivalent is subtracted from the patient’s available allotment.
Troubleshooting
- Discrepancies can occur if the POS system uses the product’s UnitThcContent instead of the lab result THC value, leading to mismatches with METRC’s calculation.
- The correct approach is to always use the lab result THC value for concentrates to match METRC’s allotment deduction.
