The meth simply sped up his exit.

The Queens high-school principal busted with small bags of methamphetamine this week was on his way out for poor performance anyway, Department of Education officials said yesterday.

Second-year Flushing HS Principal Carl Hudson Jr., was arrested near the school late Tuesday after cops pulled him over for not signaling properly, and allegedly spotted the plastic bags of meth. Hudson got a conditional discharge.

DOE officials said they had been planning to remove Hudson regardless of his arrest. They said they’re reviewing the matter, but wouldn’t disclose officially whether they’ll try to give him the boot.

Parents of kids at the school were angry.

“It’s such a shock to hear that this principal could conduct himself like this. What an embarrassment!” said Contessa Keller. “Kids in here need much better role models.”
