Why do drug users have body odor?

Drug users may have body odor due to several factors, including changes in metabolism, poor hygiene, and the effects of certain substances on the body. Some drugs can cause excessive sweating or alter the way the body processes odors, while others may lead to neglect of personal care. Additionally, the use of substances like alcohol or illicit drugs can impact the liver and other organs, further contributing to body odor. Overall, a combination of physiological changes and lifestyle choices often plays a role.
