Yeah, and those "statistics" about how many drivers in accidents tested positive for marijuana is crap too. Sure, maybe that many people had THC in their systems, but that just means they had gotten high sometime in the past several weeks, and they're trying to imply that all those people were high when they had the accident. Sure it may slow your reaction time down a little and it might not be the brightest idea for an inexperienced driver to drive high, but they're trying to associate it with phenomena like drunk driving where not only is reaction time slowed but coordination is completely fucked up.

And so what if marijuana contains 4 times as much tar causing chemicals as tobacco? TAR DOES NOT CAUSE LUNG CANCER, RADIOACTIVE TOBACCO DOES. But the media, the politicians, and their buddies the tobacco giants don't want you to know that.
