Instead of the fentanyl fufu drinks, a big party in a sealed room where the air is slowly replaced by helium.

People would start talking funny and die laughing, or just falling asleep while laughing. I suppose the dying would take a few more breaths.

Whomever was tasked to clean the mess up would have smiling corpses to dispose of. That would be easier, wouldn't it?

Make it mandatory that cult members have at least 7 doses of the vaxx and your final party would be helpful for the kooks and society at large.

The problem is most people want to point a finger rather than their thumb when dealing with challenges.
