💡 Tips for Using This Calculator

  • Flower: THC typically ranges from 15-30%. Premium flower can hit 30%+.
  • Vape Carts: Usually 70-95% THC. A 0.5g cart at 85% has ~425mg THC.
  • Concentrates: 60-99% THC. Great value if you dab.
  • Edibles: Fixed dose (e.g., 100mg total). Just divide price by mg.
  • Best Deals: Look for products under $0.10/mg for excellent value.

Why Calculate Price Per Milligram of THC?

Florida medical marijuana patients often struggle to compare deals across dispensaries because products vary in potency and size. A $40 eighth (3.5g) at 20% THC offers very different value than a $40 eighth at 28% THC. By calculating the cost per milligram of active THC, you can make apples-to-apples comparisons and find the best deals.

How to Use THC Percentage

Check the product label or COA (Certificate of Analysis) for the THC percentage. For flower, this is typically 15-30%. For concentrates and vapes, expect 60-95%. Edibles always list total THC in milligrams, so you can skip the percentage calculation.
