First, we’re told we can’t fly our planes if we’re also using Chantix to quit smoking. Now, we can’t drive our rigs, either. The Federal Motor Carrier Safety Administration has issued a warning that advises medical examiners “to not qualify anyone currently using this medication for commercial motor vehicle licenses,” according to The Wall Street Journal.

The move follows a study by the Institute of Safe Medication Practices that found a host of side effects linked to Pfizer’s quit-smoking pill - serious accidents and falls, potentially lethal cardiac rhythm disturbances, severe skin reactions, acute myocardial infarction, seizures, diabetess, psychosis, aggression and suicide. The FMCSA, by the way, oversees interstate trucking and bus activity.

In all the study, linked Chantix to nearly 1,000 serious adverse events. Just hours after the study was released two days ago, the Federal Aviation Administration banned the drug for pilots and air traffic controllers. So far, though, the FDA, which previously issued health advisories about psychiatric side effects, such as suicide, hasn’t taken any additional action.
