This was one of the more memorable trends during my years in primary school.
Many of my classmates used to "smoke" smarties in a similar fashion to cigarettes and marijuana. They used textbooks to crush the Smarties' candies into bit until it was powdery, creating a smoking effect. The principal would later ban Smarties on campus, and would expel students immediacy if they were caught "smoking" some Smarties.
So have you ever indulged in this particular trend?
