There is much misinformation out there. I agree with you on the assertion of Hemp based CBD oil extracted.
I can personally attest to the fact the CBD Oil that helped Charlotte in the attached article also helped me. I went from 2 to 3 hours of broken sleep per night to now 8 to 9 hours of unbroken sleep per night additionally relieving pain.
What you didn't get from this misleading article are the quality issues such as contaminates caused by how it was grown pesticides, fungicides, and types of fertilizers used. How it was processed and what it was diluted with to get at the reported CBD level. Other contaminates can come from funguses such as powdery mildew which can be harmful if inhaled or ingested. But all things considered CBD is CBD no matter if the original source is hemp, marijuana or Hopps.
