Louisiana's House of Representatives recently approved legislation prohibiting 'chemtrails,' the alleged chemical trails from aircraft, despite scientific consensus that they don't exist. This move aligns with actions in eight other states, including Florida and Tennessee, aiming to outlaw 'geo-engineering' or 'weather modification' activities. Critics argue these laws may hinder legitimate scientific research and aviation operations.

The bill mandates the Department of Environmental Quality to document reported chemtrail sightings and forward complaints to the Louisiana Air National Guard. While lacking penalties, it calls for further investigation. Opponents fear potential disruptions to airline routes and legal challenges against carriers, emphasizing the need for evidence-based policymaking.

A 2016 study revealed that 10% of Americans believe in chemtrails, with an additional 20-30% considering the theory 'somewhat true,' highlighting the persistence of this conspiracy.
