The Different Types of Drugs


Marijuana is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant. Marijuana has a chemical in it called tetrahydrocannabinol, better known as THC. All forms of marijuana are mind-altering (psychoactive). In other words, they change how the brain works. A lot of other chemicals are found in marijuana, too — about 400 of them, some of which are carcinogenic. Marijuana is addictive with more teens in treatment with a primary diagnosis of marijuana dependence than for all other illicit drugs combined


Impaired judgment and motor coordination / Shortened attention span and distractibility / Anxiety and panic attacks /Increased heart rate / Increased risk of heart attack / Increased risk for schizophrenia in vulnerable individuals / Impaired judgment / Problems with memory and learning / Lowered motivation / Decreased alertness and coordination / Addiction / Withdrawal symptoms from stopping drug use (in a chronic user): irritability, sleeplessness, anxiety, impaired appetite, and aggression.


Cocaine is a powerfully addictive stimulant drug. The powdered form of cocaine is either snorted or injected. Crack is cocaine that comes in a rock crystal that is heated and smoked. The term “crack” refers to the crackling sound produced by the rock as it is heated.Many cocaine users report that they seek but fail to achieve the same experience as they had with their first use. Some users will increase their dose in an attempt to intensify and prolong the effect, but this can also increase the risk of adverse psychological or physiological effects


Increased body temperature, heart rate, and blood pressure / Headaches / Abdominal pain and nausea / Decreased appetite, resulting in malnutrition / Irritability, restlessness, anxiety, and paranoia / Paranoid psychosis (loss of touch with reality and auditory hallucinations) / Addiction or dependence


Heroin is a highly addictive white or brown powder or brown sticky tar made from opium poppies. Users may snort, smoke or inject it. Heroin is a depressant. It enters the brain, where it is converted to morphine and binds to receptors known as opioid receptors. These receptors are located in many areas of the brain that deal with pain but also within the brain stem — important for automatic processes critical for life, such as breathing, and blood pressure. Heroin overdoses frequently involve a suppression of respiration.


Warm flushing of the skin / Dry mouth / Heavy feeling in the extremities / Nausea / Vomiting / Severe itching / Clouded mental functions / Infectious diseases, including HIV/AIDS and hepatitis (from injection needles) / Collapsed veins / Infection of the heart lining and valves / Abscesses at the injection location / Liver or kidney disease



MDMA, known as Ecstasy, is a chemical that is usually taken orally as a capsule or tablet. It is a man-made drug that is chemically similar to both stimulants and hallucinogens. It distorts the perception of time and the sense of touch. Taking Ecstasy causes chemical changes in the brain that affect your mood, appetite and sleep


Confusion / Depression / Sleep problems / Severe anxiety / Muscle tension / Involuntary teeth clenching / Nausea / Blurred vision / Faintness / Chills or sweating / Dependence and withdrawal effects (fatigue, loss of appetite, depressed feelings, and trouble concentrating) / Some problems can occur while or soon after taking the drug, others come days or weeks after taking Ecstasy.

Hallucinogens, LSD and PCP

Hallucinogens are strong mood-changing drugs with unpredictable psychological effects.LSD, or "acid," is sold as tablets, capsules, liquid, or on absorbent paper.PCP is illegally manufactured as tablets, capsules, or colored powder and can be snorted, smoked or eaten. Other hallucinogens can come in many forms, including plants and cough suppressants.

Methamphetamine, or meth, is a highly addictive synthetic chemical that acts as a stimulant. It is snorted, injected, smoked, or swallowed. Most of the methamphetamine abused in this country comes from foreign or domestic superlabs, although it can also be made in small, illegal laboratories, where its production endangers the people in the labs, their neighbors, and the environment.


Increased respiration, rapid heart rate, irregular heartbeat, increased blood pressure, and hyperthermia (when the body overheats) / Unhealthy weight loss / Severe dental problems / Anxiety, confusion, insomnia, mood disturbances, and violent behavior / Psychotic features, including paranoia, visual and auditory hallucinations, and delusions (for example, the sensation of insects "Meth Bugs" creeping under the skin)


Prescription Drug 

Prescription drugs are medicines that are prescribed to a patient by a doctor to manage pain, treat or cure a health condition such as pain, mental disease, diabetes, cancer, or common infections. These drugs are regulated by the Food and Drug Administration (FDA) and are shown to have medical benefits when prescribed and taken exactly as directed by a health provider. For people who are suffering, these drugs allow them to control their symptoms, cure or treat their diseases, control pain, or fight an infection. However, these medicines are only safe when taken exactly as directed by a doctor, healthcare provider, or as indicated on the packaging. This includes following directions on dosages, how often to take these drugs, and never taking any drug that is not prescribed for you.

Over-the-Counter Drug Abuse 

Over-the-counter (OTC) drugs are medications that can be purchased at a pharmacy, grocery, or convenience store without a prescription to treat the symptoms of common colds or pains, such as a headache. The Food and Drug Administration (FDA) has determined that these medications have medical benefits for common ailments and are safe for general consumption if taken exactly as prescribed by the packaging.

Rohypnol, the trade name for flunitrazepam, has been a concern for the last few years because of its abuse as a "date rape" drug. In reference to date rape, this drug is most commonly referred to as a "roofie."
