Stimulants, such as caffeine and amphetamines, increase alertness and energy, making them useful in treating conditions like ADHD. On the other hand, depressants, including alcohol and benzodiazepines, promote relaxation and can help with anxiety but carry risks of addiction and withdrawal symptoms. Understanding the effects, medical uses, and potential risks of these substances is crucial for making informed decisions about their use. Both stimulants and depressants play significant roles in medicine, but they must be used responsibly to avoid negative health consequences.
