What are the signs that someone is a drug dealer?

Signs that someone may be a drug dealer can include frequent, unexplained absences, particularly during odd hours, and a sudden influx of wealth or expensive items that seem inconsistent with their job or lifestyle. They might also have a large number of visitors at their home or frequent locations, particularly at unusual times. Additionally, the presence of paraphernalia such as scales, baggies, or large amounts of cash can be indicators. Finally, they may display secretive behavior or have a network of contacts involved in illicit activities.
