This is just a topic about what you think about smoking. But, do you want smoking to be illegal? If you want to decide, you've came to the right place to make a smoke-free environment! If you want to say yes or no, you need a description of your opinion.
For example-
I'm saying yes because it will give you lung, tongue, and mouth cancer. Smoking will also give you heart disease. Smoking can even cause blood clot and stroke. I think smoking should be illegal.
So, that was an example of what your description will look like. So, decide yes or no, and have a description.
