Except the drug does not "override trauma". It actually causes you to forget the memory you are recalling. Judging by your username, I'm going to guess you are familiar with the operation of DRAM: it must periodically be refreshed by reading the data out and then writing it back in. Human memory works the same way (albeit without the requirement of continual refresh). The drug in the article interrupts the write-back process, and the memory is then lost.
