About This Course

This course covers ASTM D8196 Standard Practice for Determination of Water Activity in Cannabis Flower and D8197 Specification for Maintaining Acceptable Water Activity Range for Dry Cannabis Flower. The course includes information on what water activity is, the importance of water activity control, and economic and regulatory considerations.

Learning Outcomes

By the end of this course you will be able to:

  • Define water activity in technical and in lay terms
  • Compare the difference between water activity and moisture content
  • Iterate the ideal water activity range for cannabis flower specified in D8197
  • Explain the risk of consuming cannabis stored at water activity greater than 0.65 or less than 0.55
  • Identify the steps to properly perform a water activity measurement
  • Evaluate options and provide means to successfully maintaining the proper aw in cannabis flower
  • Recognize the economic implications of aw control
  • Identify how inspecting for water activity range reduces chance of diversion

Course Outline

This course should take approximately one hour to complete and is organized into the following sections:

  • Introduction
  • Learning Outcomes
  • What is Water Activity (aw)
  • Why is it important to control aw to < 0.65?
  • Why is it important to control to > 0.55?
  • The risk of using a moisture content specification
  • Measurement of aw of Cannabis Flower
  • Control of aw in cannabis flower
  • Economic Considerations

Who Should Attend

The course is appropriate for anyone in the Cannabis industry including business owners, producers, regulators, and consumers.

ASTM Standards Referenced

This course makes reference to and includes the following ASTM Standards:

  • ASTM D8196 Standard Practice for Determination of Water Activity (aw) in Cannabis Flower
  • ASTM D8197 Standard Specification for Maintaining Acceptable Water Activity (aw) Range (0.55 to 0.65) for Dry Cannabis Flower

How Learning Will Be Assessed

Learning will be assessed by completing the course and passing the assessment with a score of 80% or higher.
