Can you take beta-blockers while vaping CBD oil?

"I take Metoprolol daily."

You can take beta-blockers and CBD oil together but you must do so cautiously. Beta- blockers slow down your heart rate while cannabis increases your heart rate. Beta-blockers and cannabis both lower blood pressure and the additive effect may be to much. Look out for dizziness, fainting, irregular heart beat, fatigue and confusion.
