I estimate that most students will focus on the harm when writing such articles, and talk about how smoking and drinking are bad. If we follow this routine, of course, it is not impossible, but I don't think readers will like it. But we must never sing praises for these actually harmful things. What shall we do? My idea is to cut into the subject from another angle:

We never mentioned the content in the video. At the beginning, we might as well list some data directly, such as the percentage of tobacco and alcohol products in a certain year's GDP, total tax revenue, import and export balance, export tax rebate and so on.

The second part analyzes and comments on these data.

The third part deeply discusses why people know that these things are harmful, but they account for an increasing proportion in people's daily consumption. It is best to combine the historical and cultural market for a deeper discussion.

Fourth, in fact, this is the end. Finally, you should give your own views on the questions raised in the third part.
