Question

sophias doctor suspects shes been using marijuana for a long period of time. which set of symptoms best describes what sophias doctor observes? sophia exhibits impaired memory and learning. sophia is hoarse and malnourished with nosebleeds. sophia complains of itching, nausea, and a racing heart. sophia has severe dental problems, anxiety, and a sleep disorder.

Explanation:

Marijuana use, especially long - term, can affect the brain's function. The main psychoactive component of marijuana, THC, acts on cannabinoid receptors in the brain. These receptors are involved in various functions including memory and learning. Long - term use can lead to impairment in these cognitive functions.
Hoarseness, nosebleeds, and malnourishment are more associated with substances like cocaine (especially crack cocaine which is often smoked and can damage the nasal passages and throat). Itching, nausea, and a racing heart are symptoms that can be seen in a variety of conditions (e.g., allergic reactions, some heart conditions) but are not the most characteristic of long - term marijuana use. Severe dental problems (like "meth mouth" in methamphetamine users) and some of the other symptoms mentioned are not the primary symptoms of long - term marijuana use.

Answer:

Sophia exhibits impaired memory and learning.
