Should smoking be banned in campuses and public places?

Order Description
a persuasive speech targeting a policy.
The title is if we should ban smoking in campuses and public spaces.

My side on the topic is YES it should be banned.

The speech should focus on 3 main points. one of the main points should focus on environmental aspect. The two main points are up to the writer to choose, maybe health concerns, etc.

As for the sources, one source for each point would be appreciated as a supporting material.

This is a persuasive speech, it should sound strong and uses a vivid language.
No visual aids are required. No presentations. It is a 9 minutes persuasive speech on a policy.
“creative writing” as a subject areas for the sake of the order, the main points can be diverse. Environmental, health, etc…
