Wie soll ich meine E teilen?

The fact that the part contains 280 mg of MDMA is at best a mutation without drug checking. It is not unusual, however, that it is actually a pill which is overdosed in this way. Nevertheless, it should be ensured that MDMA is also present and not any other active substance. This is possible using test kits. Details here: https://www.eve-rave.org/drogen-abc/drugchecking/

Apart from that, I agree that it would not be reasonable to take half a part if one assumes such a high dosage. A quarter would be less risky. Of course still not unrisk. It should also be borne in mind that the material in the pill can be distributed unevenly, which is why a division of the pill does not have to lead to a corresponding division of the dose. If the part is pre-powdered (compare homogenized), it can be split up better.
