What action will the FAA take if you are caught smoking marijuana?

The correct answer highlights the serious implications of marijuana use for someone holding a pilot certificate. The FAA views drug use, including marijuana, as a significant safety risk in aviation. If a remote pilot is found to be violating drug regulations, the FAA has the authority to take immediate action to protect public safety. This includes the possibility of suspending or revoking the pilot's certificate. The rationale is straightforward: ensuring that all pilots operate under a standard of fitness and safety, which is compromised by substance use.

The other options may seem plausible, but they do not accurately reflect the FAA's stringent regulations regarding drug use. Warnings or fines might be considered in less critical scenarios, yet when it comes to aviation safety and the implications of drug use, the FAA prioritizes direct action to address potential risks. Similarly, while a mandatory drug test could be a component of the process, the immediate suspension or revocation of a pilot certificate is the definitive and appropriate action in cases where public safety is at stake.
