Good point. In The Netherlands there is quite some data available about pills and their contents. The official thingie is that every pill can contain something else. I mean, two completely identical pills could contain completely different doses (or substances). That is a fact. Is it likely to happen ?? It is possible. There is always a chance that you end up buying (hypothetical, I mean...we would never do that ...would we ??...) 1000 pills that look the same but the amount of mdma in each varies from 20 to 160 mg. How can that happen ?? Well, the machine that mixes the substance with the binder broke down so we decided to use .... (anything that lies around.....) and do it ourselves.
Anyway, if one from a batch is 'OK', it definitely does NOT mean, the rest of the batch is/contains the same (chances are but NO guarantee).
You never know who made it and the is no such thing as product...liability...(or guarantee).You have to _try_ to take control, try to be in charge. If you decide to experiment with Ecstasy, be responsible. It is your life and you HAVE to be careful.
(And be careful with the test kit too because the Reagent really is nasty)
aj (who wishes that that 12 year old Trimbos database with all pills ever found in the NL was available for all of us....)
