Well I'll bite. Since tobacco was NOT ALLOWED to be regulated by the FDA until last year AND the FDA has made ZERO changes in cigarettes in the year it has had its regulatory power, then I can assume that FDA regulation has had ZERO benefit. And more importantly I can assume that since the country kept trucking during the couple hundred years of UNREGULATED tobacco, that UNREGULATED MJ will not harm the community.
Tobacco related deaths are huge yearly and the tobacco companies add thousands of chemicals and adulterants to their product and then nicely package it for sale in 7/11s. If someone wanted their weed sold in Walmart, 7/11, or Costco I could see the need for packaging but I'm sure growers and stores can work out packaging without government help.
You are just completely wrong if you think tomatoes are inspected by the gvt. There are regulations about how much chemicals and the like you spray on your crops but there are no police checking the tomatoes or making sure that the farmer doesn't have more than 25' of tomatoes. If the US Government had any ability to control food quality we wouldn't have e-coli outbreaks every week.
Why is ANY regulation of this plant necessary?
And exactly what is your point. Check pesticide regulations and tests in Ca. Keep in mind that the government is hampered by understaffed resources and enforcement is weak as it will be with cannabis in a legal framework.
As the Bill to have the FDA regulate tobacco was only passed in June 2009 there is yet a long way to go and again the FDA is hampered by lack of resources. Look man, stop throwing up distorted information - post links and relative information that support your arguments. No legislation is perfect - it never has been and never will be. What should we do overthrow the government and introduce anarchy. Well while you do that why not vote to end prohibition?

"Why is ANY regulation of this plant necessary?" It's called prohibition at the moment and based on your views you'd have it kept that way.
