👉 Illegal fluids, often referred to as "drugs" or "controlled substances," are substances that are prohibited by law due to their potential for abuse, harm, or other serious consequences. These can include prescription medications like opioids, stimulants, and sedatives when misused or diverted from their intended medical use. The term "fluid" here can be misleading, as these substances are not liquids but rather chemicals or compounds that can be administered intravenously, inhaled, or ingested. Their illegal use is strictly regulated and punishable by law due to their dangerous effects, including addiction, overdose, and death.
