  Illegality doesn't help, but there are jurisdictions where marijuana is legal. In fact there are plenty of studies, but the answers are so disparate that the original study authors reasonably chose not to factor them in: depending on whose studies you believe, a couple of joints a day could be a bit more likely to induce lung cancer than a few cigarettes, pose a negligible risk or even mildly reduce the risk if you're already smoking the tobacco. A bigger (although not entirely unrelated) problem than legal status is that controlling for appropriate variables is an absolute minefield when studying usage of something as heavily correlated with certain demographics, behaviours and attitudes as cannabis.

  Marijuana and Heroin are both Schedule 1. the reasons for this cannot possibly be objective (and aren't).
