Could you reference a study that makes that claim? I've never heard that before.

There are a couple listed here; some are from pro-cannabis campaigners. http://medicalmarijuana.procon.org/view.answers.php?questionID=636 http://medicalmarijuana.procon.org/view.answers.php?question... Erowid has a nice chart. See benzene. https://www.erowid.org/plants/cannabis/cannabis_info3.shtml https://www.erowid.org/plants/cannabis/cannabis_info3.shtml The british pro-drug site has a summary of some research: http://www.ukcia.org/research/smoke-contents.php http://www.ukcia.org/research/smoke-contents.php This UK National health service "behind the headlines" report looks at one study and how it was reported. http://www.nhs.uk/news/2012/06june/Pages/cannabis-lung-health-risks-underestimated.aspx http://www.nhs.uk/news/2012/06june/Pages/cannabis-lung-healt... > The report says that the constituents of cannabis smoke are similar to those of tobacco smoke apart from the presence of THC (which is only in cannabis) or nicotine (which is only in tobacco). This means that cannabis smoke has the same carcinogens (substances that cause cancer) as tobacco smoke, although concentrations of these may be up to 50% higher. Like tobacco, cannabis also contains toxic carbon monoxide. > It also points out that although people generally smoke cannabis less often than tobacco cigarettes, the way they inhale means the amount of smoke reaching the lungs is greater. The respiratory tract and the rest of the body may also retain far more of the products of cannabis smoke than when smoking a similar quantity of tobacco. Given the similarities in their constituents, there is concern that regularly smoking cannabis could have similar health risks as regular tobacco smoking, says the BLF. > Also, people often mix cannabis with tobacco. There is strong evidence that smoking tobacco causes lung cancer and chronic lung disease. This makes it difficult to isolate whether health problems are specifically caused by cannabis or tobacco, says the report.
