Earlier this month, Lancaster emergency medical services responded to 65 drug overdoses during a three-day period. None of the overdoses were fatal, most occurred in Lancaster city. Officials blamed it on a bad batch of synthetic marijuana.

Synthetic cannabis, or "spice," uses chemicals to artificially mimic the composition of real marijuana but manufacturers typically use dangerous cleaners and consumer products found at stores. Nobody really knows how batches are made and users don't know what they're ingesting.

Spice can is often sold in retail stores, usually under the counter. It's cheap, easy to find and frequently marketed to youths. Lancaster County District Attorney Craig Stedman said in a statement, "While we are in the midst of a still-escalating opioid abuse epidemic, we must not forget the many other poisons being dealt and used in our communities."

On the Monday edition of Smart Talk, we'll discuss the dangers of synthetic marijuana and methods used to catch manufacturers and distributors. DA Stedman will join Special Agent Patrick Trainor of the DEA's Philadelphia Field Division to talk about synthetic marijuana in the region.

Also, the Cold War ended 26 years ago and the threat of nuclear annihilation at the hands of the Soviet Empire faded away. In 2017, the world is confronting a very different type of nuclear power in North Korea. As tensions mount on the Korean Peninsula, people are once again confronting an antagonistic nuclear threat.

Smart Talk discusses renewed feelings of nuclear anxiety and how those fears have contributed to culture from the dawn of the nuclear age to present day with Dan Zak, a feature writer with The Washington Post and author of Almighty, an "examination of America's love-hate relationship with nuclear weapons."
