My advice is to don't do illegal drugs or bath salts or hang out with people that do. All those drugs are really just a form of psychosis and may very well take you down that rabbit hole, especially if one is predisposed to schizophrenia or psychosis. People need good healthy sleep where they can have dreams in order to stay mentally healthy.
It sounds like you need to fix that sewer pipe vent in B's attic.
