As drplatypus said the pills were GCMS tested to contain LSD, and as he has also indicated this is a very uncommon occurrence. In my posts regarding the issue from last year, I had suggested that the pills would not contain LSD as this is uncommon, but rather would contain a research chemical.
Enlighten has been working towards the goal of one day having a GCMS program in place to allow exact identifications of unknown substances. It is a situation like this where only a GCMS test can give a definitive answer. A previous thread on this issue discusses a range of chemicals, and I hope this shows how useless it is when you try to determine a chemical based on physical effects. This will not be an isolated incident, and over the coming years RC's will be used as adulterants within pills (and potentially blotters), increasing the need for fast identification to inform those who may unknowingly think their pill contains 'ecstasy'.
The information Enlighten received regarding this issue was via the RADAR team, who we have worked along side in Adelaide over the last year. Enlighten decided not to make any statement due to the very delicate nature regarding GCMS testing in Australia, until the police had given their press statement regarding the active substance within these pills, which was based on a recent seizure rather than data collected by Enlighten and RADAR last year. The samples that were analysed last year returned no result, as only a small scraping from pills collected were analysed, rather than the whole pill.
What I think is also important to point out is that the only way we (as a society) will be able to have an accurate indication of exactly what is contained within pills sold on the street is for groups like Enlighten, RADAR, and police organisations to work together in collating, testing, and subsequently informing users quickly. This is the only way a potential disaster can be avoided.
If the police rely on only seizures, they are not getting an exact indication of what is being sold on the streets at that point in time. An example of this is on one Melbourne weekend we tested 22 individual designs, of which potentially could have been GCMS tested. I don't know how many pills the police were aware of and had seized and tested, but I suggest it would not have been close to 22.
Although the adulterant was LSD, it could have potentially been something worse such as PMA. I believe government organisations are seeing the wisdom shown by drplatypus's RADAR team and Enlighten, and the potential disaster than can be avoided by establishing a GCMS program which provides accurate information to the end user so they can make a more informed choice.
