Module 6: Dosage Calculations
Welcome to Module 6 of the Cannabis Consumer Safety Course. This comprehensive module covers essential information about calculating and understanding dosages for cannabis and hemp products.
Section 6.1: Understanding Cannabinoid Measurements
Learning Objectives
- Understand different measurement units used in cannabis products
- Learn to interpret product labels and laboratory results
- Comprehend potency ranges across various product types
- Recognize industry measurement standards
Common Measurement Units
Percentage (%)
- Primary use: Flower and concentrates[1]
- Calculation: Weight of cannabinoid per total weight
- Example: 20% THC = 200mg per gram
- Typical ranges:
- Flower: 10-30%[2]
- Concentrates: 60-90%[3]
Milligrams (mg)
- Primary use: Edibles and tinctures[4]
- Measurement: Absolute weight of cannabinoids
- Example: 10mg THC per gummy
- Product-specific ranges vary
Product-Specific Measurements
Flower Measurements[5]
- Total cannabinoid percentage
- THC vs THCA values
- Total potential THC calculation
- Moisture content consideration
Concentrate Measurements[6]
- Higher percentage measurements
- Potency ranges by type
- Residual solvent testing
- Terpene content percentage
Important Note: Understanding how cannabinoid content is measured and displayed on different products is crucial for accurate dosing and safe consumption. Always verify that measurements are clearly stated and come from certified testing facilities.[7]
Reading Laboratory Results
Certificate of Analysis (CoA)[8]
- Cannabinoid profile breakdown
- Testing methodology used
- Measurement uncertainty
- Laboratory accreditation
Key Measurements[9]
- Active cannabinoid content
- Total potential cannabinoids
- Detection limits
- Testing date and batch information
Understanding Potency Ranges
Flower Categories[10]
- Low potency: 5-10% THC
- Medium potency: 10-20% THC
- High potency: 20-30% THC
- Ultra-high potency: >30% THC
Concentrate Categories[11]
- Standard extracts: 50-70%
- High-purity extracts: 70-90%
- Isolates: 90-99.9%
- Full-spectrum considerations
Measurement Standards
Testing Requirements[12]
- State-specific regulations
- Testing frequency requirements
- Acceptable variance ranges
- Reporting format standards
Quality Control[13]
- Laboratory accreditation standards
- Sample selection protocols
- Chain of custody documentation
- Result verification processes
Section Summary
Understanding these measurement fundamentals provides the foundation for accurate dosing calculations and conversions, which will be covered in the following sections.[14]
