After a bit of looking, Nova found a few references to the substances that the "client" was concerned about.  But all those really told her was that researchers had discovered a general class of naturally occurring chemicals, mostly made by very simple life forms, that seemed to open human (and similarly functioning creatures, like Vargr and Aslan) minds to increased susceptibility to telepathy.  In certain cases, the user also found his or her own abilities slightly increased, but the hypnotic side effect of the drug made that almost useless.<br/><br/>A bit more searching did find something else.  A single string of research had found that a pain neurotransmitter, the enigmatically named "Substance P", seemed to bond with the subject chemicals, rendering both inert.  But the rest of the information was in a Part B of the report, something that appeared to have not been published yet.  There was no mention of the effects of either sedatives or barbiturates on the chemicals that she could find.<br/><br/>"Substance P" could actually be found for purchase in limited quantities, primarily for research purposes.  Their price was fairly reasonable...<br/><br/>The other doctor rubbed his eyes (after about an hour of searching).  "All I can find for sale is a general psi effects blocker.  But it's a bit unreliable.  In fact, one author cites a psi helmet as being more effective than his own synthesized anti-psi meds, but he continued work because of the utility of having a non-visible psi defense.  Probably helped that the he was working his way through several Imperial grants in the process of the study."  He paused, then said, "We should probably have some of this stuff couriered out to us.  We've got a little over an hour, and the starport medical facility may be able to get some for us.  What did you find?"<br/><br/>He flipped a switch, and called up the Bridge on a communication panel.  "Bridge, this is Doctor Helopolis.  I'm going to place a rush order for some medical supplies.  Would the Captain be willing to hold off lifting until they are delivered?"<br/><br/>A slightly tinny voice on the other end of the line replied, "Hold on, Doctor.  We'll check."
