🧠 Understanding Stimulants
Stimulants are substances that speed up the activity of the central nervous system. They increase alertness, energy, and attention. Think of them as substances that put your body and mind into overdrive.
- ⚡ Definition: Substances that increase the activity of the central nervous system.
- 📈 Effects: Increased heart rate, blood pressure, and brain function.
- ☕ Examples: Caffeine, nicotine, amphetamines, and cocaine.
😴 Understanding Depressants
Depressants, on the other hand, slow down the central nervous system. They reduce alertness, reaction time, and can induce relaxation or sleep. They essentially have the opposite effect of stimulants.
- 📉 Definition: Substances that decrease the activity of the central nervous system.
- 🧘 Effects: Reduced heart rate, blood pressure, and brain function; drowsiness.
- 🍺 Examples: Alcohol, benzodiazepines (like Valium), and opioids.
