I concur with Sasaki above.

And this claim is absolute tosh. Do you have any statistics to back up your claim that people you smoke pot are more likely to smoke cigarettes?

And secondly do you have any reliable data of any documented death where the cause was marijuana in its 2000+ years of human usage? Do you have any reliable data of it causing cancer? I can assure you that you won't find cancer marijuana cases, due to the chemical make up of the plant. It doesn't create the same toxic concoction that tobacco does after burning (especially when smoked through a bong). Actually I could list over 200 human illnesses that marijuana is an effective treatment for, so much for health issues.

And that doesn't even take into account the superior quality of fabric hemp produces over, the inefficient to produce, cotton.
