Yes, SpaceX does drug test depending on the position.
Multiple current and former employees report that SpaceX does not drug test, except in instances of on-the-job accidents.
However, the job descriptions for security officers, positions requiring top secret clearance, mission positions, and satellite positions on the SpaceX careers website state that those applying for the position are subject to pre-employment drug tests and random drug and alcohol tests thereafter.
Recently, Elon Musk, the founder, CEO, and chief engineer of SpaceX, discussed in an interview that after smoking marijuana on the Joe Rogan Show in 2018, “the whole of SpaceX” including himself were subject to random drug tests by the government for a year.
This is because SpaceX receives government funding from the Department of Defense, marijuana is illegal on the federal level, and the federal government maintains a drug-free work environment.
In addition, a 2019 email from Elon Musk to SpaceX employees obtained the Washington Post states: “SpaceX maintains a drug free workplace… SpaceX personnel may not use or possess any controlled substance while in the workplace, and also may not be under the influence of legal or illegal drugs while at work…Anyone who appears to be inebriated or under the influence while at work is subject to drug testing and potentially other employment actions.”
This information was obtained after many hours of painstaking research from various websites with answers from current and former SpaceX employees. The SpaceX careers website only discusses drug testing for certain positions, although Elon Musk has stated that SpaceX is a drug-free workplace.
