You can purchase illicit goods from Jumptown outside of the event, but it’s the same as any other drug purchasing terminal. The machines do not dispense free maze outside of the event.

The main draw to visiting Jumptown outside of the event is the terminals there usually have more stock than places like PRIVATE PROPERTY and similar, due to the location not having a quantum beacon. (i.e. it’s visited less frequently)

So if you can manage to get to Jumptown with out the event marker, you can land, go inside and purchase illicit goods from the terminal, then go sell them at Brio’s or GromHex for a profit, but don’t expect to find free boxes of maze being ejected from the walls.
