From the Industry, For the Industry. • Charas Scientific is a product of Colorado’s marijuana industry and brings a fresh approach to testing • We understand cannabis at the molecular level and empower our clients to use that knowledge • Charas delivers more than just results, we offer solutions to problems that we find in testing • Our team of scientists innovate new products and methods to take cannabis to the next level
  6. 6. Potency Testing • All retail marijuana including flower, concentrates and edibles must be tested for potency prior to sale • Product must be labelled with potency test results • Cannabinoids required: • THC, THCA, CBD, CBDA, CBN
  7. 7. Chemical Contaminant Testing • Some chemical contaminant testing is mandatory, and some is random. • The testing rules are dynamic, so it is important to stay current on them to avoid violations • Current Mandatory Testing (August 2014) • Residual Solvents • Current Random Testing • Pesticides and Heavy Metals
  8. 8. Residual Solvent Testing • All concentrates made with chemical solvents must be tested for residuals • Solvents allowed for use: propane, butane, acetone, ethanol, isopropanol, water, heptane and CO2 • Current Approved Solvent Limits • Butane < 800 ppm (parts per million) • Heptane < 500 ppm
  9. 9. Biological Contaminant Testing • Biological contaminant testing is required for most retail marijuana including flower, edibles and some concentrates • Must test for harmful E. coli, Salmonella and Aspergillus • Current limits for all microbes are <1 CFU (colony forming unit)
  10. 10. Who Must Test? • All retail marijuana products must be tested prior to sale by the producer • Growers AKA OPCs • Infused product and extraction companies AKA MIPs • Retail stores are generally not required to test products
  11. 11. How Often Do You Test? • Every harvest batch and production batch must be tested for potency • Pooling of packages or harvest and production batches produced within 7 days is allowed for contaminant testing • Validation program is designed to reduce testing burden on producers • Once validated, producers only need to test 10% of batches for contaminants
  12. 12. OPC Validation • Cultivation Facilities (OPCs) can be validated to reduce testing burden • Potency: Test four harvest batches produced three weeks apart within six months • Contaminants: Test every harvest batch for 12 weeks, minimum of 12 batches separated by 6 days
  13. 13. MIP Validation • Marijuana Infused Product companies (MIPs) can be validated to reduce testing burden • Potency: Every batch of concentrate and edible must be tested • Contaminants: Every batch within 4 week period, minimum of 4 batches separated by 6 day period
