You probably can't, the best you can likely do is to get them to not care about the conspiracies so much. That would be my approach, don't argue the conspiracy with them, ask how it affects them on a day to day basis and if said conspiracy is true, is there anything they can really do to change it. Reinforce that their life may be better if they just try to ignore and enjoy themselves instead of constantly worrying about the conspiracy they believe. Ask them to take a week off from it and see if it improves their mental state.
