According to JAMA Study and John Hopkins, almost a 25% CBD and hemp products sold today contain THC. Most of these products do not list THC in the product labeling. John Hopkins lab tested a single instance of vaping cannabis that has 0.39% THC in it (similar to the legal allowance in hemp of 0.3%) can result in a positive drug test for THC.
John Hopkins is continuing the studying the potential to produce impairing drug effects of taking CBD/Hemp in regards to the administration (vaping, oil, jellies, etc.) and dosage.
It is important to be aware of possibility of the impairing affects CBD/Hemp could have. Always consult your doctor before taking.
When buying CBD, make sure to look at recent testing reports for that brand. Retailers should have these reports online – if they do NOT, then don’t buy from them!
HappyHippie.com recommends: Plus CBD Oil for their consistent quality and testing practices.
