Drug pipe

They usually consist of a glass tube with or without a bulb, the latter particularly used when freebasing methamphetamine or crack cocaine.

A pipe that has been used will have carbon deposit on the exterior of the bulb and white or gray crystal residues on the inner surface.

There are some legitimate uses for these pipes including applying the hole "on the top of an eucalyptus bottle" for inhaling aromas or moisture.

While ostensibly intended as romantic gifts, their primary known use is as a pipe to smoke drugs such as crack cocaine or methamphetamine.

[11] They are commonly sold at convenience stores in the United States, particularly in inner-city locations.
