I have a brother who is using drugs heavily and i need to get him into rehab and i remember from my time living in Thailand 10 years ago that there was a centre run by buddhist monks and they got people to drink some herbal medicine that made them sick and it cured them of their craving for drugs.I cant remember where the centre was but i wonder does anyone on this forum have information about the this place i read about? many tnx.
