According to the study, smoking three marijuana cigarettes a day can cause the same damage as 20 cigarettes. And those who smoke both marijuana and cigarettes are further increasing their risk of lung damage.

Dr. Mark Britton, chairman of the foundation, said that tar from cannabis cigarettes contains 50 percent more carcinogens than tobacco. Since marijuana smokers tend to inhale up to four times more deeply than tobacco users, more poisonous carbon monoxide and tar enter the lungs, he added.

"These statistics will come as a surprise to many people, especially those who choose to smoke cannabis rather than tobacco in the belief it is safer for them," said Britton. "It is vital that people are fully aware of the dangers so they can make an educated decision and know the damage they may be causing."

As a result of the study's findings, the group is urging the British government to implement a public-health education campaign on the health risks of marijuana smoking.

Its funny how people have the wrong idea about which is more harmful tobacco or marijuana. Most people think tobacco is more harmful. I think its a good idea that the group urges the British government to implement an educational campaign.
