With respect to drinking water to avoid overheating and dehydration, you should be careful of the dangers of overhydration, which has also been a cause of ecstasy and other drug-related deaths.

Some people, being aware of the danger of dehydration in relation to ecstasy use, resort to drinking vast quantities of water to prevent this. This leads to an oversaturation of fluids in the body, causing minerals to diffuse out of the cells where they can be used, either into the digestive tract, where they are excreted as waste, causing a defficiency, or into the bloodstream, where they can be transported to other locations in the body, in which case some minerals and other substances may have a toxic effect.
