I’ve seen a lot of anti-smoking ads, and learned a lot of reasons smoking is bad for you, but this video really drives the message home. It’s a vine that shows a healthy lung inflating, followed by a smoker’s lung inflating. While you may hear that tar can change the lung black, and make breathing like sucking through a straw. In this case, after reading this post on Flash by Self, seeing really is believing. Even if it’s not 100% medically accurate, at least it gets the message across that smoking sucks, right? Right.
