Methamphetamine is a powerful, cheap drug and it is a growing problem in some surprising parts of America. Unlike crack cocaine, which primarily targeted the inner-city during its reign of terror in the 1980's, crank is making it's mark in Small Town, U.S.A. The drug's users range from middle class and well-educated people to teens -- even mothers who have passed on their addictions to their babies. One of the reasons crank is growing so quickly is that methamphetamine is easily produced in makeshift labs from inexpensive raw materials. In addition, users experience a "high" lasting up to 30 hours -- much longer than many other drugs. "Methamphetamine may be the worst drug ever to hit America," says retired General Barry McAffrey, the nation's Drug Czar. "It's expanding in a very bizarre manner. It's all over the Midwest. It's in Idaho, Arizona, Hawaii, San Francisco, Southern California. It's now showing up in Georgia." Crank's explosive growth is being fueled by mass production labs run by Mexican nationals. Authorities say they produce up to 95% of the crank on America's streets. CBS News 48 Hours took a close look at methamphetamine on Thursday, and found a drug that threatens to tear apart the lives of countless Americans. Could your community be at risk?

After ravaging parts of the Caribbean and Florida, Hurricane Georges recharged and slammed into the Gulf of Mexico, flooding the Gulf Coast with rain measured in feet instead of inches. Property damage from the storm -- which once packed 174 mile-an-hour gusts -- are expected to reach the $2 billion mark. With at least 300 confirmed dead in the Caribbean, the human costs are incalculable. But even with such grisly statistics, Hurricane Georges was by no means the most powerful or costly storm to blow through this part of the world. And even in a field as unpredictable as the weather, it is a virtual certainty that the coming years will bring more hurricanes, more damage and more death. What causes these monstrous storms to form? If a hurricane were headed your way, would you know what to do? On Thursday, CBS News 48 Hours took an in-depth look at hurricanes and the path of misery left in their wake.

Among the singular people you'll meet on this week's show: Rick Nagle: a detective with the Cold Case Unit of the Massachusetts State Police.

He spends hours going over every aspect of the crime, even visiting crime scenes that are decades old to get a sense of how the murderer was thinking. Talking about the victims whose cases he tries to close after so many years, Nagle says: "I look at those pictures [of the victims] a lot and I reflect on them. It reminds me that they're gone and there's no one to speak for them, and that's why I get emotional."

Imagine being so worried about germs that you feel compelled to wash your hands dozens of times a day, or so concerned about giving the correct change that you count the coins over and over before you give them to the cashier.

CBS News 48 Hours takes a look at this strange malady. You'll meet men and women who must battle their obsession every minute of every day.

Howie deals with his obsession without psychological help. He has a special guest house in his backyard, to which he repairs when his wife or children are sick. But Howie says he is content: "I couldn't be happier. I'm probably the most happy neurotic person in the world." Jeremy Lyons, a 16-year-old tenth grader from Milwaukee who is so terrified of germs that he takes three-hour showers.

Both Rebecca and Picabo are being treated by the same doctor, and they strike up a friendship. Over their months of rehab, they become closer and closer. They take a vacation together to a spa in Arizona, and Rebecca decides that she will attempt to scale a 45-foot high rock-climbing wall. Before she'd come down with RSD, she'd been an avid rock climber, and she wants to conquer this obstacle. Amazingly, she does it, and in the process gives herself - and Picabo - a sense of the power of the human will. Robert Garcia, a 33-year-old man who also suffers from RSD.

It's every parent's nightmare: a missing child. With every passing hour, the tendency to think the worst grows. CBS News' 48 Hours reports on how parents and authorities responded in three cases. Traci Rene Conrad: On Feb. 25, 1996, Traci, an 11-year-old girl who lived in California's Central Valley, disappeared. Authorities and local people spent the next 25 days searching frantically for the little girl, often slogging their way through pouring rain. Finally, Rene's body was found in a kiln, just a few blocks from the Conrads' house. The kiln belonged to the Galik family, and police soon arrested a former truck driver named Kevin Galik, then 37. When she disappeared, Rene had been on her way to visit Galik's children. She was found wrapped in a sheet matching those inside the Galik home, and a man's T-shirt was wrapped around her head. The shirt was Kevin Galik's size. Galik claimed innocence, but at his trial, prosecutors produced several witnesses who undercut his alibi. He was convicted of murder and sentenced to life in prison without the possibility of parole. Rene's parents, Chris and Terri, have since become vocal advocates for better, quicker police response to child-related crimes.
