CBD and Potential Drug Interactions Certain substances such as (CBD, THC, grapefruit, St. John’s Wort, watercress, etc.) can affect drug metabolism, making certain drugs metabolize faster or slower than they would on their own. Cannabidiol (CBD) can temporarily inhibit the one of the most common metabolism pathways (CYP450) ability to metabolize certain drugs leading to an increase (or decrease) in blood levels, unwanted side effects, and sometimes, an overdose. Some pharmaceuticals, called “prodrugs” (tamoxifen,5-FU, Simvastatin, Levodopa, Enalapril) don’t become functional until they are metabolized into an active component. If CBD or THC slow the metabolism of a pro-drug, it can adversely affect final levels of the desired active drug. If you have been hospitalized resulting from CBD use or taking any of the below drugs consult with your doctor prior to registering.
