Feeling this way on Planet Earth may indeed indicate drug use. Feeling this way while whizzing toward Mars may instead be a case of “space brain.”
Before breathing a sigh of relief (assuming oxygen is available), consider this: space brain may be worse than heroin addiction. At least some have kicked heroin; we don’t yet know if it’s possible to overcome space brain.
Caused by “exposure to galactic cosmic rays,” space brain could result in “severe and progressive cognitive deficits.” According to a UC Irvine study, rodents that were exposed to comparable levels of radiation suffered long-term “brain inflammation and neural damage.”
This could certainly put a damper on journeys to Mars. Researchers are therefore working to develop highly-shielded spacecraft, as well as to develop medications that bolster immunity against radiation.
