Final answer:
The major factors making it difficult to remain drug-free include peer pressure, social isolation, depression, low parental education, and a history of childhood mistreatment. While peer pressure is directly mentioned as a challenging factor, the other factors indirectly contribute to the risk by influencing one's emotional state and support systems. Parental involvement, planning ahead, and being a role model are supportive in drug recovery.
Step-by-step explanation:
The factors that can make it more difficult for a person to remain drug-free include: peer pressure, social isolation, depression, low parental education, and a history of mistreatment as a child. Peer pressure may influence someone to experiment with or continue using substances, especially during adolescence, in order to fit in or gain approval from friends. Additionally, factors such as social isolation and depression can increase the likelihood of substance use as individuals may turn to drugs to cope with their feelings. Moreover, low parental education and a history of childhood mistreatment are associated with a higher risk of substance abuse and difficulty remaining drug-free.
It is essential to note that planning ahead, being a role model, and parental involvement are typically factors that support recovery and help individuals maintain a drug-free life, rather than make it more difficult. Therefore, from the options given, only peer pressure is a factor that contributes to the difficulty of remaining drug-free.
