Your Brain on Eggs.

Both videos are similar in that they both argue that drugs will indefinitely destroy the brain. The two videos both use eggs to represent the brain and frying pans to destroy the egg. Likewise, they imply that the brain will be decimated on the first use by instantly frying/ smashing the egg. In the both videos, pathos is the most prominent strategy. The first video shows us a raw egg one second and a fried one the next. The second video shows us the emotional performance of a teenager and things being smashed and broken. We recognize things being smashed as a negative action which the video associates with drugs. At the end of the videos the narrator asks rhetorically, "Any questions?" and the video immediately ends. The immediate ending tells us that there are absolutely no questions and if there are you can ask them to Captain Crunch in the next commercial.
The videos contrast in more ways that they are similar. In the earlier video a disembodied narrator sends a short message to general audience. The first video is also more general in that it uses "drugs" rather than "heroin". Since the more recent video is more specific in naming its drug, it is trying to reach a certain audience. Likewise the recent video uses a teenager (a rock star, in fact) that appears in the video rather than just a voice over. The teenager, Rachael Lee Cook, grabs the attention of other teens and also goes on to show what happens to your body, family, friends and so on. Cook also gets angry and smashes things causing the audience to be shocked and to pay attention during the commercial. Without a doubt the loud, emotion performance of Rachael Lee Cook provides a much more effective argument than the dull, disembodied 80's narrator that drugs should not be used.
