  • There is currently NO over-sight by the U.S. Food & Drug Administration of the CBD Industry.
  • Over-The-Counter CBD products claim to contain CBD from hemp. Some do. Some do not.
  • Many CBD products that claim to contain CBD are fraudulent, containing no CBD at all.
  • More than 600 CBD products tested in Colorado were found to be THC-rich with little or no CBD.


  • THC (the psychoactive component in cannabis) is cumulative, meaning it builds-up in the body over long periods of use.5
  • Even the smallest amounts of THC can accumulate in the system with repeated use.
  • At this time, use of CBD products may yield a positive drug test result due to the THC content.
  • An individual may test negative for THC for a few weeks and then test positive once the THC accumulates.


  • THC resides in the body’s fat cells, which include the brain.
  • At this time there is no scientific measurement of impairment, however one can be considered under-the-influence of an impairing substance if the THC accumulates in measurable amounts.

Use of CBD products is a “Buyer Beware” situation, because one never knows what they are consuming!
