Parched 2: Hangry (2019) on Netflix

Plot summary

Ligi runs a travel vlog with a large following, and her viewers also ask about the friends who appear in it, among them the sardonic Charlene, the nurse Ez and the fun-loving Renaldo. She gathers eight of them at a lake house for a weekend of partying she plans to film. Xavi, a chemist in the group, has carried along an orexogenic, an appetite stimulant he says water makes stronger. Shonda, a voluntary patient at the facility where Ez works, is the newest arrival. After a first night of drinking and spooky stories around the fire pit, Xavi's chemistry kit ends up in the lake, and in the morning most of the group goes in for a swim.
