yes but nearly all mass shooters are ON PSYCHIATRIC PILLS who's black box label (legally demanded warning label) says they cause suicide depression and organ failure (and obsession - which is a huge factor in murder)
if it were the CDC has ALLOT of explaining to do
if MARAJUANA were the key factor in mass murder (not psych pills and alcohol) then it should have been "exposed" and kept out of the country (ie, using agen orange - illegal but EFFECTIVE)
i doubt marajuana is any kind of leading factor, personally
BUT IF IT WERE I'D KILL THE PEOPLE SELLING IT for promoting mass murder
