Final answer:
Nikki is experiencing a social barrier due to peer pressure from her friend Lana, who is trying to convince her to take stolen prescription pills. The social dynamics of friendship and the desire to fit in are influencing Nikki's decision-making process.
Step-by-step explanation:
Nikki faces a social barrier in the situation described. Her friend Lana is pressuring her to engage in risky behavior by taking stolen prescription pills, which represents a challenge involving peer influence and social norms. This type of pressure can make it difficult for individuals, especially teenagers, to make safe and healthy decisions because of the desire to fit in or maintain friendships.
It is important for Nikki to consider the serious health risks associated with taking medication that is not prescribed to her, including potential side effects, interactions with other substances, and the risk of developing a substance use disorder. Seeking support from trusted adults, such as a family member or school counselor, can be an important step in overcoming this social barrier and making a decision that prioritizes her health and well-being.
