A blinding tube assembly for concealing a drug delivery tube includes a blinding tube having a tubular sleeve that bounds a compartment and a tubular dispersing stem projecting from an end of the sleeve. A drug delivery tube is inserted into the compartment through and access opening opposite the dispersing stem. The drug delivery tube has a tubular body and a dispensing stem extending from a drug delivery end thereof. A tubular bushing is disposed about the dispensing stem such that when the drug delivery tube is inserted, the dispensing stem is received into the dispersing stem of the blinding tube with the bushing disposed therebetween. An annular end face of the dispensing stem is not visible through a dispersing opening in the dispersing stem from outside the blinding tube.
