How may sudden weight change reflect substance abuse?

Sudden weight change can serve as a significant indicator of possible substance misuse. Many substances can influence appetite, metabolism, and overall health, leading to rapid fluctuations in weight. For instance, stimulants such as cocaine or methamphetamine can decrease appetite and lead to weight loss, while depressants like alcohol or opioids may cause weight gain due to changes in metabolism and increased caloric intake. Therefore, noticeable changes in a person's weight over a short period can be a red flag for assessing potential substance abuse issues. Recognizing this connection allows officers and healthcare professionals to better evaluate the behavior and health of individuals who may be struggling with addiction-related challenges.
