From statehouses to the White House, attitudes toward marijuana laws are changing. California's top tax collector is endorsing proposed state legislation to legalize and tax pot, and Republican Gov. Arnold Schwarzenegger says he'd like the idea debated. More than a dozen other states have enacted or are considering laws to permit medical-marijuana use or remove criminal penalties for possession. In Congress, Democratic Sen. Jim Webb of Virginia -- a hard-nosed Marine combat veteran -- wants marijuana legalization considered in a top-to-bottom review of sentencing and drug laws. Full-scale, nationwide legalization still seems distant, but the Obama administration has declared a hands-off approach toward California's medical-marijuana outlets, unless the state-sanctioned sites are determined to be trafficking operations. Opponents of marijuana legalization object on moral and health grounds, but the opposition appears to be weakening, especially in a time when the economic crisis is cutting into police and prison budgets nationwide.
