• Overdose: The capsules contain highly variable amounts of the active ingredient, sometimes exceeding\(200 \text{ mg}\)which increases the risk of severe toxicity, hyperthermia or death. 
• Unknown substances: The illicit market does not guarantee the purity or composition of the capsules. 
• Drug interactions: Combining with other stimulants (cocaine) or certain medications (antidepressants) is particularly dangerous. 

 Risk Reduction

• Dosage knowledge: A recommended single dose of MDMA is generally estimated to be between\(1 \text{ mg}\)And\(1,5 \text{ mg}\)per kilogram of body weight.
• Drug testing: Drug checking in specialized centers is the only way to identify the product before consumption.
• Hydration: When in use, it is advisable to drink water regularly (approximately\(0,5 \text{ L}\)per hour of dancing), without excess.
