Prescription drugs are used for a multitude of purposes, from fighting off infections to reducing pain. While they are legal when used in the correct manner by the person with the prescription, use by unauthorized individuals for other purposes is not legal and can actually get you in trouble with the law. Very Well Mind explains the ramifications of using drugs without a prescription.
The practice of wiretapping is nothing new. Government officials have been secretly monitoring individuals' telephone conversations for decades.
It can be surprising how much a person's life can change due to a minor traffic stop. Not from any traffic violation itself, but what can stem from it. For example, two men from Tennessee were recently pulled over by police simply for traffic violations, but ended up being charged with the drug crimes of possession of marijuana with intent to distribute, as well as drug trafficking in cocaine.
When authorities make an arrest they sometimes look to charge the suspects involved with whatever they can, even if they are not related to the reason they initially made the arrest. For example, if someone is arrested for drug possession but the authorities also find materials that could be used to make drugs, the authorities may also charge the suspect with other drug crimes such as drug manufacturing.
