The Orlando Magic are feeling pretty good with a 3-1 lead on the Detroit Pistons in the NBA playoffs … or maybe it’s the drugs they’re seemingly pretending to sniff that’s got ’em riding high.

Prior to Monday’s big Game 4 victory over the top seed in the Eastern Conference, Noah Penda and Goga Bitadze got each other hyped up with a unique routine.

While waiting in the Kia Center tunnels, they started it off with some standard hand slaps and a shivering gesture … then Bitadze put his hand out for Penda to chop up an imaginary substance before taking a sniff.

Whatever it was, they should keep doing it — the Magic went on to defend homecourt with a 94-88 victory to take a commanding lead in the first-round series. Bitadze had a couple points and six rebounds.

Desmond Bane led the way for Orlando … securing 22 points on the night.

The apparent drug-inspired celebrations are nothing new in sports — remember when Michigan baseball player Mitch Voit snorted the third-base line last year??

He later apologized for that.

Speaking of celebrations, Grizzlies star Ja Morant was in attendance in Orlando … and showed support for his old teammate when Bane hit a three-pointer by making a gun gesture that previously got him fined $75by the league.

Game 5 is Wednesday night … we’ll see if the Magic bump the Pistons outta the postseason or if they coke.
