If you want to enjoy your monthly crack but dodge the psychosis, try getting a script for "Seroquel", it's an anti-psychotic that will remove or block the dopamine somehow and it over-rides any stimulant as far as I know, so it should work for crack.
Then you should hypothetically be able to have your little monthly "crack-party", make sure to be well rested so why not start in the day instead of the night?
Then right when you feel the on-set of paranoia pop like 100-200mg of "Seroquel" eat a banana or two drink some fluid with electrolytes maybe add half a valium to the mix and go to sleep, no paranoia, good-long sleep.
You will feel tired asf and be a bit swollen the next day. But you will most likely dodge the paranoia.
Then again not in favor of paranoia, or "Seroquel".
But fear seems to be trendy right now with the pandemic and everything, that we are supposed to be scared, it's the general vibe right now. So maybe you should chill with the "crack-party" concept and wait until after the stupid "pandemic"? Bless!
