Hello!! Schools that use a no-tolerance policy are followed by consequences. My school has no-tolerance policies for drugs, alcohol, bullying, etc. If you are caught with any of these, then you will suspended or expelled, depending on the seriousness of the charge. Basically, if schools have these policies, it will be followed by a serious consequence given by the principal/teacher. I hope I have helped!! Let me know if you have any more questions. Have a great day. :)
