Harm Reduction Grapefruit Juice Interactions with Psychoactive And Non-psychoactive Drugs.

[user63525]

Hi , i have been searching the internet to find potentially dangerous interactions between Grapefruit juice and certain drugs but i have not been able to come to a conclusive answer for each drug.

The drugs in question are ;

MDMA
Cetirizine hydrochloride
Dextromethorphan (DXM)
Promethazine
CBD + THC
Cholecalciferol (Vitamin D)
Codeine
Ketamine
5-Hydroxytryptophan (5-HTP)

Any help would be greatly appreciated and i thank you in advance for any of your answers.

A studio shows increased potentiality in oral isomer s ketamine ingestion if subjects tooked grapefruit once a day a week earlier and the day of intake.

1 litre of pure grapefruit juice consumed an hours or so in advance massively potentiates loperamide when used to stop opiate withdrawal... So much so that I have managed to completely halt WDs from a substantial fent patch addiction this way..

The downside being that the amount of lope needed was what many would call excessive and certainly dangerous (200-220mg). It was only something I did every once in a while in a dire emergency though....
