Question:

If someone has arrhythmia, is it safe to consume medical grade marijuana? 

If some one has arrhythmia, is it safe to consume medical grade marijuana? The reason is it can cause a drop in blood pressure -- is this true?

submitted by Jake from Michigan on 2/3/2013

Answer:

by Texas Heart Institute cardiologist, Scott R. Sherron, MD  Scott R. Sherron, MD

The acute cardiovascular effects of marijuana use have been extensively studied although predominately in young healthy males. There is a slight increase in resting BP and a predictable increase in heart rate. This is related to an increase in sympathetic tone and can be blunted with B-blockers. Sympathetic stimulation is a common trigger for several arrhythmias and B-blockade is a mainstay of therapy. Marijuana use has been specifically associated with bouts of atrial fibrillation. Therefore, there are numerous reasons that the use of even medical grade marijuana would be ill-advised with a history of arrhythmia.   

Hope that is helpful.
