ToddCast Vol. XX: CBD researcher Alex Capano, Ph.D., studies at the Lambert Center for the Study of Medicinal Cannabis and Hemp at Thomas Jefferson University in Philadelphia. Her groundbreaking work was on CBD for opioid addiction—which also found, not surprisingly, quality of life improvements around pain, sleep and anxiety. Natural Products Insider senior editor Todd Runestad sat at the bench with Capano to discuss the frontiers of CBD research. Listen in as they discuss:

  • Safety concerns around liver toxicity, drug interactions, and whether drowsiness is a side effect or an effect.

  • The best way to take hemp CBD—a loading dose, or start low and go slow?

  • What the science says around possible maximum upper intake dosages.
