I've heard that people have been able to successfully smuggle drugs using balloons before, is that true?

Yes, balloons have been used as a form of aerial transportation for smuggling drugs across borders. Balloons are often filled with lighter-than-air helium, hydrogen or hot air and are used to transport illicit substances above detection equipment at checkpoints. They have successfully been used to transport substances such as marijuana, cocaine and heroin and have been used to bypass border patrol agents and drug-sniffing dogs. The drugs are often attached to the walls of the balloon or hidden inside of the balloon envelope.
