Mardi Gras beads on ceiling ok?

Carlsbad CA

Description

(Serious) I've had these beads up a few years. They're plastic but the weight adds up. I wanted to put another 25 pounds worth up there, on the side that has less beads. Is there a risk of my ceiling coming down? They are attached with command hooks. Once in awhile one necklace falls when the front door slams. I'm not sure how the ceiling was made/materials/strength. Thanks for the advice.
