     A new weapon is on the way in the fight against smoking in Europe. Soon when smokers buy

cigarettes, they might see a shocking photo of a blackened lung or a cancer patient staring back at

them from the packet.

     Some boys may think of smoking ascool and sexy. Their friends won't agree

when they see their packets of cigarettes lying on the table.

    The European Union announced onOctober 22, that it had chosen 42

photos that showed the damage cigarettes could do to the body. It called on member nations to

put these pictures on packets to discourage young smokers.

   To catch the attention of teenagers, the special packets warn of long-term medical dangers, like

cancer. Short-term effects, like bad skin, are also on the list.

    "The true fact of smoking is disease, death and horror. That is the message we should send to

the young," said David Byrne, an EU health official. "Hopefully these pictures will shock students

out of their love for cigarettes. "

    The EU head office hoped the pictures would work better than current written warnings on packs

of cigarettes. The warning included "smoking kills" and "smoking can lead to a slow and painful death. "

    So far, Ireland and Belgium have shown interest in the photos. Canada has used similar pictures and

warnings on cigarette packs since 2000. The country has recently seen a fall in the number of smokers.

     According to studies, smoking is the single biggest cause of avoidable death in EU. Every year more

than 650, 000 smokers die, more than one person a minute.
