At this point, we all know smoking leads to some pretty serious health complications, including lung disease, stroke, heart disease, chronic obstructive pulmonary disease (COPD), gum disease, and certain types of cancer. Of course, that list is not exhaustive. Health care researchers are working every day to provide a comprehensive look at all that can go wrong with smoking.

The Centers for Disease Control and Prevention’s 2015 “Tips from Former Smokers” campaign is now focusing on some of the lesser known side effects of tobacco use, including macular degeneration and colon cancer.

"Please don't end up like me. Don't sit in a doctor's chair, have a clamp put on your eye, and have needles stuck in your eyeballs. It's horrible," Marlene, the 68-year-old subject of the CDC’s new campaign, who is currently being treated for macular degeneration, told NBC News.

In another advertisement from the campaign, Julia, 58, shows viewers how to use her colostomy bag, which she now requires after developing colon cancer.

Similar to the CDC’s previous campaign platform, this newest catch of ads shows the potential risks that await someone who picks up smoking in jaw-dropping fashion. Representatives from the CDC say no matter how shocking the images, you can’t argue with results.

"Over a million and a half smokers made a quit attempt because of our 12-week campaign — just a 12-week campaign created this effect," Dr. Tim McAfee, director of CDC's Office on Smoking and Health, told NBC News. "Over a 100,000 people quit successfully and permanently because of the campaign."
