Colloquially referred to as a methoscope, a love rose consists of a glass tube with a paper or plastic rose inside of it, and a bit of cork or foil on the ends to keep the rose from falling out. While ostensibly intended as romantic gifts, their primary known use is as a pipe to smoke drugs such as crack cocaine or methamphetamine. They are commonly sold at convenience stores in the United States, particularly in inner-city locations.
Crack cocaine users remove the cork or foil from the ends, discard the rose, and put a small piece of copper scouring pad or similar metallic material into the end to act as a "filter". The pipes are not durable, and must be replaced often.
Another variant known as a pizzo, commonly used as a pipe for the consumption of methamphetamine, has a round bulbous shape opposite the open end of the glass tube.
