Does Fentanyl have yellow dye

Fentanyl itself does not contain yellow dye; it is a potent synthetic opioid that is typically a white powder or a clear liquid. However, illicitly manufactured fentanyl may be mixed with other substances or cut with various additives, which could potentially include dyes for identification or aesthetic purposes. It’s important to note that the appearance of street drugs can vary significantly. Always exercise caution and seek information from reliable sources.
