Laws affect almost every aspect of our personal lives as well as civic society.
For example, many countries regulate tobacco, alcohol, and very mind-altering substances such as opioids and marijuana. In some countries these substances are illegal and in others some may only be usable by adults and others only with prescriptions. Buying, selling, or consuming such substances in manners violating these laws can result in criminal convictions.
Laws also regulate the safety of products ranging from food to medications to motor vehicles. This means that in countries with strong regulatory environments and enforcement, consumers can have a certain degree of confidence in the safety of the products they consume or use.
Most countries also regulate traffic. Laws create order out of chaos and increase road safety by licensing drivers, ensuring that vehicles conform to safety and emissions standards, and that traffic flows in a safe and orderly fashion. Disobeying these laws can result in suspended driving privileges or even criminal charges.
Other sets of laws define certain acts as criminal and specify the types of penalties for committing such acts. Most countries outlaw murder, stealing, rape, and other forms of behavior that might endanger other people.
