Water is also a solvent and at high quantities is also toxic. No where did the lab (an no, they weren't a DEA or FDA lab, they are labs that are registered with the DEA and FDA, they don't work for the DEA or FDA) say they found those chemicals to be at toxic levels.
The chemicals that were found to be present are also found in all cooking oils as it is part of the manufacturing process. The sample that was tested was the Gold RSHO and it is a mixture of the CBD hemp oil and hemp seed oil.
FYI...every time you eat fried food, you are eating the chemicals that were found in the sample.
