Huffing a substance or inhalant can be done in a variety of different ways. In this image, amyl nitrate (poppers) is being inhaled directly from the small container that it often comes in. Other substances can be soaked in rags or gloves or even hair accessories and then those items are sniffed or huffed to get the effect of the inhalant. Other times, inhalants are put into a paper or plastic bag and are breathed in that way. Balloons are sometimes used like a bag to inhale a substance. Other inhalant's fumes are huffed directly from their containers. Other times, the inhalant is sprayed directly into the mouth. The method of inhaling depends upon the inhalant and the container it comes in and even just personal preference.
