Marijuana policy ads protected as "free speech." In a stinging rebuke, a federal judge strikes down a law prohibiting the display of marijuana policy reform ads in public transit systems, saying the governments attempt to censor ads was "illegitimate and constitutionally impermissible." The judge also issues a permanent injunction prohibiting its enforcement. The law, known as the "Istook Amendment," cuts off more than $3 billion in federal funding from local transit authorities nationwide that accept advertisements critical of current marijuana laws. The court ruled that Americans have a right to hear the message that marijuana prohibition has been a cruel and expensive failure.
