I tried as much as I could to provide a proper set and setting for everyone, and i paid special attention to their own comfort. I have experienced every emotion with these people that they could possibly display. I live with the majority of them, and the one who visited had lived with us prior for several months. I know of their psychedelic history, and have handled meltdowns of the sober variety several, several times. I have personally had to deal with their manic episodes.
"I can bet you have no idea what to do for these people if they loose it"
I have had to personally chase down one of them, sober, around my neighborhood as her schizophrenic episode triggered a flight reaction. I have also had to deal with episodes contained in close quarters where she had fight triggers.
All of these individuals, before deciding to partake, had seem me indulge my own dimethyl palette several, if not several dozen times. It was not a mystery drug I pulled out of my magical medicine cabinet, it is a household commodity that is freely available to anyone at anytime.
The only person unaware of the medicine's existence was the last to go, and she had done so of her own accord after she thought she had an understanding of the possible outcomes.
