Heineken (4-CMC and unknown substance)
Risk assessment
This pill, declared as MDMA, contains a high amount of 4-CMC (4-chloromethcathinone), an unexplored new psychoactive substance. 4-CMC belongs to the cathinone group and is structurally related to mephedrone (4-MMC). 4-CMC is described as having strong performance-enhancing and euphoric effects. Some users report severe headaches, as well as kidney and liver pain on the days after use. It is also reported that the substance can trigger a strong urge to re-dose, which increases the potential for addiction. No information is available on the risks, side effects and long-term consequences of 4-CMC. However, it is suspected that 4-CMC may be very neurotoxic. There are studies of chemically related compounds (4-chloramphetamine) which suggest that 4-CMC could lead to a pronounced and sustained depletion of serotonin stores. Furthermore, an unknown substance was analyzed in the pill, which is most likely a synthesis by-product or reactant.
Completely unknown is the interaction potential between 4-CMC and other substances.

Analysis
Have your substances tested in a Drug Checking
Testing
If you do not have the possibility to have substances analyzed, first test a maximum of one third of the pill, since very many high-dose pills are in circulation.
Wait and see
Wait 2 hours after taking the medication, as there are always pills with unexpected active ingredients in circulation, which can have a later onset of action.
Drinking
Remember: drink non-alcoholic and isotonic drinks (3 dl / hour) and take breaks in the fresh air from time to time to prevent overheating / dehydration.
Accept
Accept when the effect runs out, because "re-spiking" increases the toxicity (poisonousness) of MDMA.
