PSAs are getting more graphic... Are they getting your attention?

In a recent article on CNN the effectiveness of extremely graphic Public Service Announcements (PSA) was questioned. The PSAs for the Meth Project, Cervical Cancer prevention and Buzzed Driving is Drunk Driving  all are graphic, but in different ways. The Meth Project PSAs, vividly depict the way a life can crumble when young adults start using meth. The commercials are rather disturbing. They actually gave me the chills. These commercials are the most graphic. The Cervical Cancer awareness ads are realistic in their tone and setting and seek to unsettle viewers.The Buzzed Driving is Drunk Driving ads depict very serious situations that are awful and scary, but use a bit of humor to knock some sense into the viewer's head.

Buzzed Driving is Drunk Driving Ad

School administrators claim that the students have changed over the years and that they are exposed to a lot more at a younger age. I completely agree that the messages should be stronger, but the commercials like the meth projects ads are just disturbing.
Readers, do you think these ads are effective in getting peoples attention or would they make you want to change the channel?
