Step-by-step explanation:
The substances in question taken by a person for a variety of effects which can be legal or illegal include Medication, Substance, Drug, and Prescription. A drug is any substance that causes a change in an organism's physiology or psychology when consumed.
Psychoactive drugs are a particular kind of drug that alters the function of the brain, leading to changes in mood, perception, thinking, and behavior. This category includes not only illegal drugs like cocaine and LSD but also legal substances like alcohol, nicotine, and prescription medications such as opioids.
Legal medications prescribed by a doctor, which can have psychoactive effects, are used for medical purposes but sometimes are taken in doses that are too high, leading to an overdose. Such misuse can also involve taking legal prescription medications without a prescription, resulting in illegal use.
Psychoactive drug use can sometimes escalate to addiction, which is characterized by the compulsive use of the drug despite the negative consequences. Drug addiction and overdose, whether from legal or illegal substances, are serious risks associated with drug abuse. Overdoses from illegal substances and misuse of prescription medications highlight the potential dangers associated with drug use.
