Dear Dr. Roach: Two months ago, I had an upper respiratory infection that lasted for a long time, and now I suffer from fatigue. My sister suffered for a long time with the same symptoms. She took CBD and says she feels better and stronger. I had open heart surgery to replace my mitral valve, and I take metoprolol and warfarin. Is it safe for me to take CBD? — A.T.
There’s still a lot to learn about CBD
Cannabidiol, a nonpsychoactive component of cannabis (hemp), is marketed for many conditions. The scientific knowledge about its effectiveness and possible toxicities is quite limited.
