My name is Eric Wendt and I am the Chief Science Officer for Green Leaf Labs, an accredited analytical chemistry laboratory located in Portland Oregon, who has been performing hemp and cannabis testing services since 2011. We have encountered a number of issues regarding hemp testing and consumer protection in Oregon that I believe are applicable to the Federal guidelines that will be implemented. I would like to discuss the following topics during the listening section:

1.	The discrepancy between testing for delta-9 THC vs THCA and total THC.
a.	Degradation of THCA into delta-9 THC during storage and transport. 
b.	CBD concentrates and extracts produced from hemp that result in THC levels above 0.3%
c.	Importance of representative sampling of hemp material and the variability of plants in a field. 
2.	Standardized methodology for testing hemp material: equipment, extraction, procedures, instrument calibration

These are the topics I would like to comment on during the listening session. If you require a formal written statement please let me know.
