Right.

Thanks again!

The correct answer is option D: all of the above.

To arrive at this answer, let's break down the options and explain how to get the answer:

a. Chronic bronchitis and damaged lung tissue: This refers to the potential respiratory effects of long-term marijuana use. Smoking marijuana involves inhaling smoke, which can irritate and damage the lungs over time. Chronic bronchitis is a condition characterized by inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

b. Alzheimer's Disease: There is some evidence suggesting a link between long-term marijuana use and increased risk of cognitive impairments, including memory problems. However, it is important to note that the relationship between marijuana use and Alzheimer's Disease is not fully understood and further research is needed to establish a definitive connection.

c. Tongue cancer: While there is evidence linking tobacco smoking to various types of cancer, including oral cancer, the direct association between marijuana smoking and tongue cancer is still a topic of debate. However, it is worth noting that smoking in general can increase the risk of developing various types of cancer, including oral cancers.

Based on the information provided, option D encompasses all these potential risks associated with long-term marijuana use, making it the correct answer.
