     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 as cool and sexy. Their friends won't agree when they see their packets

of cigarettes lying on the table.

     The European Union announced on October 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.
