Police have praised the Sydney Mardi Gras crowd for "general good behaviour".
However they said they searched 200 partygoers and charged 96 with possessing drugs during a four hour operation involving sniffer dogs at the after party at Moore Park.
"We make no apologies for doing what we can to stop people taking drugs into this type of event," Surry Hills Local Area Command Duty Officer Inspector Stephen Crews said in a statement on Sunday.

Meanwhile seven people were arrested for offences including assaulting police, offensive behaviour and failing to comply with police directions.
About 40 people needed medical treatment during the evening.
Assistant Commissioner Mark Murdoch said there were significantly fewer arrests and incidents than previous years.
"The alcohol-free zones were well enforced and adhered to by the majority of people which greatly assisted in making it a relatively trouble-free evening."
A man was also arrested in relation to the theft of $10,000 worth of tickets to the event.
This year's figures compare to 10 arrests during the 2012 Mardi Gras, 18 at the 2011 event and 35 in 2010, police said.
