CBD From Hemp Versus Marijuana
CBD or Cannabidiol extracts, which are produced directly from marijuana flowers, are up to 15 percent CBD (or 150,000 ppm).
CBD extracts can be produced indirectly from hemp manufacture as a by-product of the flowers and leaves that are mixed in with the stalks during hemp stalk processing for fiber. This has been done mostly in Europe and 30 other countries and imported into the US until recently, as it was illegal to cultivate hemp in the US until the 2014 Farm Bill.. Now many states have voted to make hemp cultivation legal for research and industrial production
So, Currently CBD from hemp plants are usually only 25 parts per million (so 25ppm vs. 150,000 ppm CBD from cannabis flowers).
