Heroin is a powerfully addictive substance derived from morphine, a naturally occurring compound extracted from the resin of the seed pods of the opium poppy plant. This narcotic has profound effects on the mind and body, altering brain chemistry and influencing behavior and perception. Heroin can come in several forms depending on how it is manufactured and what substances it's been cut with. It may appear as a fine white or brownish powder, or in the case of what's known as “black tar heroin,” it’s a dark, sticky resinous substance resembling roofing tar.

Ecstasy is the street name commonly used to refer to a synthetic drug known scientifically as MDMA—short for 3,4-methylenedioxy-methamphetamine. It’s classified as an illegal psychoactive substance that functions primarily as a stimulant but is also known for its mild hallucinogenic effects. While the terms “ecstasy” and “molly” are sometimes used interchangeably, they don't always mean the same thing. Both refer to MDMA, but the difference lies in the form: ecstasy typically comes in colorful pills or pressed tablets, often decorated with logos or symbols, while molly usually refers to a supposedly purer form of MDMA, usually in the form of a white powder or crystalline substance.

“Speed” is a popular street term that refers to a group of stimulant drugs—substances that elevate brain activity and increase physical and mental alertness. These stimulants are often used by teenagers, young adults, and even some older individuals for various reasons: to stay awake longer, to increase concentration, to lose weight, or to simply experience an artificial high.

Drugs come in a vast array of forms, purposes, and potencies. Some are prescribed for legitimate medical reasons, others are used recreationally, and many are misused with dangerous consequences. Regardless of whether they’re legally available or illegally sold, all drugs share one common trait—they have the power to significantly alter how the body and mind function.
