The amount of caffeine in just couple cups of coffee can cause life-threatening changes in some heart rhythms. Where are the warning labels on my Folgers? You won't find any warnings in Fresh Cup Magazine either. Check for yourself:

But hey, just to make you happy, how 'bout we make marijuana legal and put a big fat warning label on it that proclaims:
CAUTION: THIS PRODUCT MAY CAUSE INJURY OR DEATH TO PEOPLE HAVING CERTAIN HEART CONDITIONS. CONSULT YOUR PHYSICIAN BEFORE USING.
That way, I am happy and you are happy. What do you say? Does this work for you?
One thing different about these examples is that it is common knowledge in our country that caffeine will increase heart rate and boost blood pressure. "Coffee nerves" is a well worn cliche. Nobody is suprised to find themselves revved up by a cup of strong coffee or tea.
Whereas the similar cardiovascular effect of pot will come as a total surprise to a lot of newbies. If pot were unbanned this would change in time, but an ethical case for unbanning it is easier to make when those who want it unbanned tell the unvarnished truth. And the unvarnished truth telling should start in places like High Times. I'd say the same thing for coffee and magazines like Fresh Cup if caffeinated drinks were currently verboten and the truth about their effects obscured by heaps of Barbra Streisand from both sides of the issue.
