A method of making an intradermal injection using a drug delivery device containing the substance to be injected. A device for practicing the method includes a needle cannula having a forward tip and a limiter portion having a skin engaging surface surrounding the needle cannula. The needle cannula is in fluid communication with the substance and the tip of the needle cannula extends beyond the skin engaging surface a distance equal to approximately 0.5 mm to 3.0 mm. The needle cannula includes a fixed angle of orientation relative to the plane of the skin engaging surface. The skin engaging surface limits penetration of the needle tip into the skin so that the substance can be expelled through the needle tip into the dermis layer. Preferably, the fixed angle of orientation of the needle cannula is generally perpendicular relative to the skin surface, and the skin engaging surface is generally flat.
