If someone's abusing the use of Cannabis, which organs of the body are badly affected quickly? Some people usually think it's the lungs or heart that gets affected immediately but I think they are wrong. It's one of the myth of using Cannabis.
I would say that every part of the body is usually affected whenever you are using cannabis too much because it has the potential of affecting one part of your body which is going to move into another and generally mess up your health.
The lungs will be certainly affected by too much using of Cannabis. The heart can also be affected too. This is why using of Cannabis should be done in a careful way to avoid having a disorder.
Cannabis can either be inhaled or ingested. This makes it possible for them to affect mostly the cardiovascular system of the body. Their main receptors is the brain.
