I thought the way that South Park put it (in the voice of Randy Marsh) many years ago was just about perfect:
“Well, Stan, the truth is marijuana probably isn't gonna make you kill people, and ...it most likely isn't gonna fund terrorists, but... Well son, pot makes you feel fine with being bored and... It's when you're bored that you should be learning some new skill or discovering some new science or... being creative. If you smoke pot you may grow up to find out that you aren't good at anything.” [0]
To be clear, I don’t wholly agree, I know too many talented and hard-working stoners, but it does sum up the passive danger of cannabis rather nicely I think.
