Hallucinogens Drugs like LSD and psilocybin that alter perceptions, thoughts, and emotions, potentially inducing hallucinations and distorted sensory experiences. The Opioid Crisis: A National Epidemic 1 Overprescribing Overuse of prescription opioids for chronic pain, leading to widespread dependence and diversion. 2 Heroin Emergence The rise of heroin use as a cheaper and more readily available alternative to prescription opioids. 3 Fentanyl's Rise The proliferation of fentanyl, a highly potent synthetic opioid, contributing to a surge in overdose deaths. Stimulants: Cocaine, Methamphetamine, and More Cocaine A powerful stimulant that produces a euphoric rush, followed by a crash and intense cravings, leading to potential heart problems, stroke, and psychosis. Methamphetamine A highly addictive stimulant known for its long-lasting effects, causing alertness, energy, and euphoria, but can also lead to paranoia, anxiety, and severe health complications. Amphetamines Stimulants like Adderall and Ritalin, typically prescribed for ADHD, but can be abused for their cognitive-enhancing and mood-boosting effects, potentially leading to dependence. Depressants: Alcohol, Benzodiazepines, and Barbiturates Alcohol A widely consumed depressant, affecting brain function, coordination, and judgment.
