Narcotic Narcotics are naturally - occurring or synthetic drug s with psychoactive and highly intoxicating properties . Narcotics are often highly addictive and taking them results in changes in perception , mood , consciousness , cognition , and behavior . During the mid - 21st century various Earth militaries controlled their soldier s through the use of drugs which produced a narcotic - like stupor . ( ) Even though trellium - D , a deadly neurotoxin to Vulcan s , is not a narcotic , it shares some similarities with narcotics . While gradually degrading the neural pathways of Vulcans , its immediate effects are in removing emotional inhibitions . Over time , use of trellium - D induces insanity and violent rages and the neurological damage becomes irreversible , eventually leading to death . ( ) T ' Pol suffered severe exposure to trellium - D while in an asteroid field and even though Doctor Phlox was able to reverse the neurological damage , T ' Pol continued to hunger for the release from the constraints of logic the trellium had allowed . She developed a method of injecting it into her body and became addicted until , with Phlox ' s help , she successfully withdrew from the substance . However , her ability to control her emotions to a normal Vulcan level was permanently damaged . ( ) In 2254 Vina described the Talosian ' s addiction to experiencing events in the thought record by comparing it to a narcotic . ( ) The inhabitants of the failed Federation colony Turkana IV often turned to narcotics as an escape from the great poverty and violence that existed there . Natasha Yar described her knowledge of the effects of narcotic drugs , from experiences she witnessed on her homeworld , to her fellow crew mates , Data and Wesley Crusher in 2364 ; they did not understand why anyone " would voluntarily become dependent upon a chemical . " ( ) The Ornaran s of planet Ornara suffered from an addiction to the narcotic created by the Brekkian s known as felicium circa 2364 . ( ) In 2373 , when the crew of the docked at Bahrat ' s space station shortly before entering the Nekrit Expanse in the Delta Quadrant , Chakotay and Tom Paris were offered Rhuludian crystal s for sale by a trader named Sutok . He explained that ingesting just one of the crystals would make days of tedious travel seem like moments of exquisite rapture . An offer Chakotay and Paris immediately turned down . ( ) During the Occupation , Bajoran slave laborers on Terok Nor often partook of narcotic drugs , referred to as " chemicals " . It was apparently common for users to be passed out on the Promenade , and for life - threatening disputes over them to arise . Users were often viewed with disgust by other Bajorans , believing that their undignified behavior justified the stereotypes Cardassian s had of Bajorans , and the Resistance refused to smuggle them off the station . ( ) Cadet - Captain Tim Watters also took narcotics over the course of his self - imposed mission during the Dominion War , in order to deal with the pressure and stress of his duties . As such , many of his actions and command decisions were quite irrational . Also , under the influence of the drugs , appeared to develop the ego - maniacal impression that both he and his crew were " special " and fated to a great destiny . Watters also appeared to develop faith in a higher power guiding his destiny , even broaching the opinion that Jake Sisko was guided to him by it to write his story . The extent to which Watter ' s actions and beliefs were due to the drugs , stress or his own free choice to avoid returning to the Federation and remain in command was never made clear . ( ) Ketracel - white , used by the Dominion to control Jem ' Hadar soldiers in the 24th century , shared many of the same pharmacological traits as a narcotic . ( , " et al . " ; )
