Final answer:
College students may engage in drug selling primarily due to economic necessity, lack of educational opportunities, and cultural pressure.
Step-by-step explanation:
The primary reason college students may engage in drug selling is typically economic necessity. Many college students face financial pressures such as student loans, tuition fees, and living expenses. Selling drugs can provide a quick source of income to help cover these expenses.
Additionally, some college students may lack access to educational and job opportunities, making drug selling an appealing option for making money.
Cultural pressure can also play a role in drug selling among college students, as peer groups or the local community may normalize or encourage involvement in the illegal drug trade.
