Using a highly sensitive new test,
scientists in Europe are reporting "convincing evidence" that marijuana smoke
damages the genetic material DNA in ways that could increase the risk of cancer.
Their study is scheduled for the June 15 issue of ACS' Chemical Research in
Toxicology, a monthly journal.
Rajinder Singh and colleagues note that
toxic substances in tobacco smoke can damage DNA and increase the risk of lung
and other cancers. However, there has been uncertainty over whether marijuana
smoke has the same effect. Scientists are especially concerned about the
toxicity of acetaldehyde, present in both tobacco and marijuana. However, it has
been difficult to measure DNA damage from acetaldehyde with conventional tests.
The scientists describe development and use of a modified mass
spectrometry method that showed clear indications that marijuana smoke damages
DNA. "In conclusion, these results provide evidence for the DNA damaging
potential of cannabis [marijuana] smoke, implying that the consumption of
cannabis cigarettes may be detrimental to human health with the possibility to
initiate cancer development," the article states. "The data obtained from this
study suggesting the DNA damaging potential of cannabis smoke highlight the need
for stringent regulation of the consumption of cannabis cigarettes, thus
limiting the development of adverse health effects such as cancer."

no shit.. same goes for cigarettes..
There will still be ppl who will stick to marijuana despite the risks.
