A Texas state lawmaker fessed up to dropping an envelope of cocaine at an Austin airport in an episode that authorities said was caught on camera.

“I do not have anyone to blame but myself,” Democratic state Rep. Poncho Nevárez told the Texas Tribune on Thursday.

Nevárez, who announced last month he wouldn’t seek reelection, dropped an envelope with his official seal Sept. 6 at Austin-Bergstrom International Airport as he climbed into a vehicle, according to an affidavit filed by state police.

It was found by airport workers, who discovered it contained baggies of white powder determined to be cocaine, authorities said.

Security cameras captured the envelope fall from Nevárez’s person as he climbed into a vehicle, police said.

State authorities filed an affidavit Oct. 29 to obtain a DNA sample from Nevarez in attempt to match saliva found on the envelope.

Nevárez, who is from Eagle Pass, hasn’t been charged in the incident, but the affidavit notes that he’s suspected of felony drug possession.

The prominent state lawmaker said “grief and addiction” were consuming him and he will seek drug treatment.

“I accept this because it is true and it will help me get better,” Nevarez told the newspaper.
