I can name all the times Spidey has drunk alcohol of the top of my head.
Once when his landlord put booz in a punch he thought was alcohol free, once when he found out MJ was pregnant, once when MJ and him got back together after a separation during JMS run.
And that's it.
Spidey does NOT drink, not even at weddings.
He might, might have drunk a glass when Cap was dead, with the rest of the New Avengers, but that was doubt worthy.
Since BND though, the crappy amateurs pretending to write him in BND have utterly ignored the fact that Peter has been a teetotaller since the start of ASM. Of course, they can't relate to a hero, so they just want him as the total zero that they feel they can relate to.
