Online market site viagogo say they have had an influx of Scottish fans selling off their tickets for the Bagerz tour.
The website has been hit by an 86% rise in listings as people off-load their passes for her gig.
Viagogo bosses say tickets are being sold for almost half the face value for the Glasgow shows, with prices from £42.05.
The popstar hit the headlines again recently for her provocative behaviour and, this week, she rejected claims she took a drug overdose as her UK tour started in London.
The 21-year-old Wrecking Ball singer arrived on stage at The O2 by descending down a long, pink slide resembling her tongue, which was protruding from a giant image of her face.
She then greeted a predominantly young crowd with swear words.
A viagogo spokesperson said: "It's been reported that Miley Cyrus has 'lost the plot' and, if ticket listings are anything to go by, it seems the star's behaviour is certainly putting off her fans - and perhaps their parents - and driving them to resell tickets.
"We have seen 86% more tickets listed on our site since Miley's first London show on Tuesday.
"Fans who still want to catch a glimpse of the singer in action can now pick up a bargain on site."
Cyrus is scheduled to perform at Glasgow's SSE Hydro on Monday.
