[env-trinity] Times-Standard- Pot farm poison; study find marijuana grows likely responsible for mammal deaths

[Joshua Allen]

Just another reason that cannabis should be decriminalized. Prohibition
does not work. It costs US over $42 billion a year in the War on Drugs for
a harmless herb that could potentially be spent elsewhere for social
investment. Yet the harm caused by the agencies against "drug-users",
society, lives, and our neighbors in Mexico goes beyond the money. Just
tack this on to the cumulative cost. Maybe if more of America toked up we
wouldn't be stuck on stupid or going to war for corporations. Though I
highly recommend everyone read "God's Middle Finger: Into the lawless heart
of the Sierra Madre" to get an idea of why they are here and in Mexico
growing.
