Final answer:
The description 'street drugs or illicit drugs without medical purpose and illegal to handle' best corresponds to illegal drugs. Illegal drugs include non-medical, psychoactive substances like LSD and heroin, which are against the law to manufacture, possess, buy, or sell.
Step-by-step explanation:
“Street drugs or illicit drugs that serve no medical purpose and are against the law for people of any age to manufacture, possess, buy, or sell,” describes illegal drugs. These are substances like LSD and heroin, which are psychoactive but have no legal or therapeutic use, making them illegal. Psychoactive drugs can have medical, ritual, or recreational purposes and include both legal and illegal substances altering mood, perception, thinking, and behavior. Examples include legally prescribed opioids that are sometimes used illegally, as well as substances like alcohol and nicotine that are legal nonprescription drugs but can be misused. Misuse of these substances can lead to addiction, which may require rehabilitation involving psychotherapy and sometimes other psychoactive drugs.
