'It shows there’s a really bad drug problem,' he said. 

His father Long Tran, state representative for Dunwoody, said: 'It doesn’t surprise me that teens would be taking drugs on campus, especially as we get closer to finals week.

'The pressure is going to be there, and for some students, they’re looking for an edge.'

Principal Bass added that the students and staff will be offered grief counselors and has encouraged parents to speak to their kids.
