''Masturbation causes blindness'' teas.
This one has truth to it, though. Cigarette causes vision loss and smokers are more likely to go blind later in life.
They already use these pictures and quotes on packs here in my country. They're really gross but I don't know if they have any remarkable effect on people. But the plain package thing is cool. I remember buying cigarettes based on package when I used to smoke a few years ago. Some of them had really cool designs.
Thank God those days are behind me now.
