Can smoking marijuana thin your blood and cause your heart to beat faster?

It's the side effect of Marijuana. Your blood pressure lowers thus increasing our heartbeat. Being worried about it is Paraoia which is another side effect. Either of these...the Paranoia and the increased heart rate can actually make the other issue worse. If you are paranoid and get worried then your heart will beat faster and thus also if you notice your heart rate is up this can start or heighten paranoia.

Hello there ibittle,

Since the poster above me has already answered your question I would just like to add that smoking marijuana is really not that good especially if you are young.

If you are experiencing these nasty side effects of smoking marijuana I believe that you are aware that you need to stop. Increased heart rate can be a sign of Paranoia and this is very common side effect and it can really be very dangerous because Paranoia sometimes can awake fears buried deep inside of you.

Also if you are afraid that your blood is thinner because of the smoking marijuana than you should also inform your doctor about your bad habits because results of blood work can lead him in a different direction.
