Speeches /
Persuasive Speech - Smoking in public should be banned [3]
I actually did this same controversial topic in my english class last year :)
You're essay is great, but here are a few comments I have
"Everyone, even the apparent one-sided marketing teams of tobacco companies, can acknowledge that smoking is bad for people's health."
Maybe you can change the word choice of "bad" to "dentrimental" or "harmful"
"As one of the most common and unhealthy of human habits, smoking, generally in public, had been regarded as a personal choice that bystanders had little control over."
I believe the first had should be has "...
has been regarded as a personal choice..."
"Among the minority, smokers and tobacco users and some members of the population are fighting to preserve their rights"
Change to "smokers, tobacco users, and some members of the population..."
Best of luck! Hope this helps :)
