Yes, parrots seem to enjoy a good 'buzz'. There is something in Australia called 'the drunken parrot season' because red collared lories would eat rotten fruit (fermentation causes the sugar in the fruit to become alcohol) and get very drunk on it -unfortunately for them, it's so unhealthy that A LOT of them actually die.

Many, many years ago, we had a rat terrier that, whenever we had a party at home (this was the 70's and we had parties all the time then), I had to tell everybody NEVER to put their drinks on the floor or he would drink from them and get drunk. We had adopted this dog not knowing he was a lush and had not taken any precautions the first time it happened and the poor thing got so drunk he couldn't walk straight. My husband thought it was very funny but I was very alarmed! Thankfully, he slept it off and was OK the next day - but it's not the same with birds so I am glad you quickly put a stop to it and threw out the idiot!
