When someone gets hurt or commits a crime, figuring out what drugs they took can be crucial. Usually, experts look for drugs in blood or other body fluids. But what if those aren't available? That's where things get tricky.

Sometimes, the only clues left are on clothes, bedding, or other items. These items can have biological materials like vomit or stains that might contain drugs. Testing these items isn't straightforward. It's not like testing blood, where methods are well-established. Each item is unique, so scientists have to adapt.

A new approach has been developed to handle these unusual samples. The process involves careful preparation, special quality control measures, and strict criteria for results. This method has successfully identified various drugs, from illegal substances to over-the-counter meds. For example, scientists found zolpidem in vomit on clothing and cocaine in stains on bedding.

This method isn't perfect, but it's a valuable tool. It can help investigators understand past drug use, link drug exposure to specific locations, or provide insights into events where a person is missing. While it has limitations, it's a step forward in forensic toxicology.

The key takeaway is that science is always finding new ways to solve problems. Even when traditional methods don't work, innovative approaches can provide answers. This method shows how important it is to think outside the box and adapt to unique challenges.
