How much MDMA does an ecstasy tablet contain?

It is not possible to tell from the outside how much MDMA an ecstasy pill contains. In addition, an ecstasy pill can also contain substances other than MDMA. The only way to know how much MDMA is in your pill is to have it tested. This can be done for free with all test services in the Netherlands.

Here you can find the annual reports of the test service.
