Which of the following is an example of substance misuse/abuse that could contribute to a crisis?

• A. Alcohol
• B. Vitamin C
• C. Water
• D. Herbal tea

Answer: (A)

Substance misuse/abuse means using a substance in a way that harms health or safety, often leading to an emergency. Alcohol stands out because it rapidly affects the nervous system, causing intoxication, impaired judgment and coordination, risky behavior, and potentially life-threatening states like alcohol poisoning or withdrawal complications. In a crisis, you may see confusion, vomiting with decreased consciousness, slow or irregular breathing, and pale or bluish skin—signs that require urgent care.

Vitamin C, water, and herbal tea aren’t typical culprits for acute emergency crises in this context. They’re generally considered safe or only problematic in unusual, extreme situations, so they don’t illustrate the same immediate risk as alcohol misuse.
