Weed smokers smoke a marijuana cigarette (joint), but may also be in a dry pipe or water. The pipe is known as a “bong”. They also mix it with food and eat or brew it as tea. Sometimes users open up cigars and remove the tobacco, replacing it with a pot called a “blunt”. Joints and blunts can sometimes be laced with other, more powerful drugs, such as crack cocaine or PCP (phencyclidine, a powerful hallucinogen).

As the typical user inhales more smoke and holds it longer than he would with a cigarette, a joint creates a severe impact on the lungs. Aside from the discomfort that goes with sore throats and chest colds, smoking one joint gives as much exposure to cancer-producing chemicals as smoking four to five cigarettes.
