Cocaine is just one of many stimulants that can do a number on your head and heart. Stimulants are drugs that speed up activity in the central nervous system (brain and spinal cord). They make the heart beat faster and cause blood vessels to narrow – which can make you feel nervous and jittery. The caffeine is a stimulant. Any stimulant – even caffeine, to a mild degree – can become addicting. Other dangerous stimulants:
• Crack is cocaine in a form that is smoked.
• Amphetamines are pills that have some legitimate medical uses only when prescribed by doctors.
• Methamphetamine is a long-acting and highly addictive stimulant. It comes in many forms including crystals (“crystal” or “ice”) and powder (called “crank”).
• Ecstasy, or methylenedioxymethamphetamine (MDMA), usually taken in pill form, is part stimulant and part hallucinogen.
