Which factor would enhance a dealing charge in Indiana?

Enhancing a dealing charge in Indiana often involves the presence of aggravating factors that indicate a greater level of danger or severity in the offense. Possessing firearms while engaged in drug dealing is a significant factor that enhances the charge because it suggests the potential for violence and poses a greater risk to public safety. Firearms associated with drug activity can imply a readiness to use force, which law enforcement and the judicial system tend to view very seriously. The presence of firearms further escalates the threat level inherent in drug dealing, which is why it is treated as an aggravating factor in the legal context.

Other factors provided in the options do not carry the same level of enhancement. For example, dealing drugs to adults, possessing drug paraphernalia, or being under 21 do not represent the same immediate threat to public safety or suggest an increased likelihood of violence associated with the drug transaction. Therefore, the presence of firearms is a clear and substantial factor in enhancing the seriousness of dealing charges in Indiana.
