The producer of viagra, Pfizer, have made this rather stomach churning ad that has been shown in cinemas in recent weeks. The ad shows a man taking drugs bought over the internet which then leads to him regurgitating a dead rat. Lovely. The ad has received a number of complaints but the ASA have decided to allow the ad to continue being broadcast due to the important message that it contains regarding the dangers of drugs bought from an unknown source. Check it out below, but hold back on eating while you do.
