Artificial intelligence. Abortion. Guns. Marijuana. Minimum wages.Name a hot topic, and chances are good theres a new law about it taking effect in 2025 in one state or another.Many of the laws launching in January are a result of legislation passed this year. Others stem from ballot measures approved by voters. Some face legal challenges.Heres a look at some of the most notable state laws taking effect:Hollywood stars and child influencersCalifornia, home to Hollywood and some of the largest technology companies, is seeking to rein in the artificial intelligence industry and put some parameters around social media stars. New laws seek to prevent the use of digital replicas of Hollywood actors and performers without permission and allow the estates of dead performers to sue over unauthorized AI use.Parents who profit from social media posts featuring their children will be required to set aside some earnings for their young influencers. A new law also allows children to sue their parents for failing to do so.Social media limitsNew social media restrictions in several states face court challenges.A Florida law bans children under 14 from having social media accounts and requires parental consent for ages 14 and 15. But enforcement is being delayed because of a lawsuit filed by two associations for online companies, with a hearing scheduled for late February.A new Tennessee law also requires parental consent for minors to open accounts on social media. NetChoice, an industry group for online businesses, is challenging the law. Another new state law requires porn websites to verify that visitors are at least 18 years old. But the Free Speech Coalition, a trade association for the adult entertainment industry, has filed a challenge.Several new California measures aimed at combating political deepfakes are also being challenged, including one requiring large social media platforms to remove deceptive content related to elections and another allowing any individual to sue for damages over the use of AI to create fabricated images or videos in political ads.School rules on genderIn a first nationally, California will start enforcing a law prohibiting school districts from adopting policies that require staff to notify parents if their children change their gender identification. The law was a priority for Democratic lawmakers who wanted to halt such policies passed by several districts.Abortion coverageMany states have passed laws limiting or protecting abortion rights since the U.S. Supreme Court overturned a nationwide right to the procedure in 2022. One of the latest is the Democratic-led state of Delaware. A law there will require the state employee health plan and Medicaid plans for lower-income residents to cover abortions with no deductible, copayments or other cost-sharing requirements.Gun controlA new Minnesota law prohibits guns with binary triggers that allow for more rapid fire, causing a weapon to fire one round when the trigger is pulled and another when it is released.In Delaware, a law adds colleges and universities to a list of school zones where guns are prohibited, with exceptions for those working in their official capacity such as law officers and commissioned security guards.Medical marijuanaKentucky is becoming the latest state to let people use marijuana for medical purposes. To apply for a state medical cannabis card, people must get written certification from a medical provider of a qualifying condition, such as cancer, multiple sclerosis, chronic pain, epilepsy, chronic nausea or post-traumatic stress disorder. Nearly four-fifths of U.S. states have now legalized medical marijuana.Minimum wagesMinimum wage workers in more than 20 states are due to receive raises in January. The highest minimum wages will be in Washington, California and Connecticut, all of which will top $16 an hour after modest increases.The largest increases are scheduled in Delaware, where the minimum wage will rise by $1.75 to $15 an hour, and in Nebraska, where a ballot measure approved by voters in 2022 will add $1.50 to the current minimum of $12 an hour.Twenty other states still follow the federal minimum wage of $7.25 an hour.Safer travelingIn Oregon, using drugs on public transit will be considered a misdemeanor crime of interfering with public transportation. While the measure worked its way through the legislature, multiple transportation officials said drug use on buses and trains, and at transit stops and stations, was making passengers and drivers feel less safe.In Missouri, law enforcement officers have spent the past 16 months issuing warnings to motorists that handheld cellphone use is illegal. Starting with the new year, penalties will kick in: a $150 fine for the first violation, progressing to $500 for third and subsequent offenses and up to 15 years imprisonment if a driver using a cellphone cause an injury or death. But police must notice a primary violation, such as speeding or weaving across lanes, to cite motorists for violating the cellphone law.Montana is the only state that hasnt banned texting while driving, according to the National Conference of State Legislatures.Tax breaksTenants in Arizona will no longer have to pay tax on their monthly rent, thanks to the repeal of a law that had allowed cities and towns to impose such taxes. While a victory for renters, the new law is a financial loss for governments. An analysis by Arizonas nonpartisan Joint Legislative Budget Committee estimated that $230 million would be lost in municipal tax revenue during the first full fiscal year of implementation.Meanwhile Alabama will offer tax credits to businesses that help employees with child care costs.Kansas is eliminating its 2% sales tax on groceries. It also is cutting individual income taxes by dropping the top tax rate, increasing a credit for child care expenses and exempting all Social Security income from taxes, among other things. Taxpayers are expected to save about $320 million a year going forward.Voting rightsAn Oklahoma law expands voting privileges to people who have been convicted of felonies but had their sentences discharged or commuted, including commutations for crimes that have been reclassified from felonies to misdemeanors. Former state Sen. George Young, an Oklahoma City Democrat, carried the bill in the Senate.I think its very important that people who have gone through trials and tribulations in their life, that we have a system that brings them back and allows them to participate as contributing citizens, Young said.Associated Press writers Trn Nguyn in Sacramento, California; Kate Payne in Tallahassee, Florida; Jonathan Mattise in Nashville, Tennessee; Randall Chase in Dover, Delaware; Steve Karnowski in Minneapolis; Bruce Schreiner in Frankfort, Kentucky; Claire Rush in Portland, Oregon; Summer Ballentine in Jefferson City, Missouri; Gabriel Sandoval in Phoenix; Kim Chandler in Montgomery, Alabama; John Hanna in Topeka, Kansas; and Sean Murphy in Oklahoma City contributed.David A.
