Please help me to correct this little paragraph
Hello everyone : )
Please can you help me to write the introduction of my paragraph ? (pleasse correct faults and if you've Ideas I'm all ears ;] )
When I go to my school I see everyone around me smoke, starting with my classemates, friends, supervisors and also teachers who are supposed to be the example,.... I become Disgusted to see that they kill themselves with a small fire, So I decide to do this modest work to find out the effects of tobacco , and I do hope that it will help (even if it's for a little bit) those who are slaves of this poison .
PS: I don't have a very good level in english, I'm not a native speaker,,,
