Habitual Pot use may lead to the following effects on the lung:

acute and chronic bronchitis;
extensive microscopic abnormalities in the cells lining the bronchial passages (bronchial epithelium), some of which may be premalignant;
overexpression of genetic markers of progression to lung cancer in bronchial tissue;
abnormally increased accumulation of inflammatory cells (alveolar macrophages) in the lung; and
impairment in the function of these immune-effector cells (reduced ability to kill microorganisms and tumor cells) and in their ability to produce protective inflammatory cytokines.



What is marijuana and how does it affect the body?

Marijuana is an illegal drug produced from the dried leaves, stems, seeds and/or flowers of the hemp plant, cannabis sativa, that is usually smoked by the user. There are many slang terms for marijuana, including, pot, grass, weed and Mary Jane. "All forms of marijuana, including the stronger sensemilla and hashish varieties, are mind-altering (psychoactive) drugs," says Wadler. "They all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana that effects changes in the brain of the user." Marijuana's effects depend on the strength or potency of the THC, which is only one of more than 400 chemicals present in marijuana. Highly fat-soluble, THC and other related chemicals rapidly enter the brain and fat stores of the body.


Within minutes of inhalation of marijuana smoke, blood levels are achieved, with peak physiologic and subjective effects occurring in 20 to 30 minutes and subjective effects lasting two to four hours. Increasing in potency over the years, marijuana is, by far, the most widely used illicit substance in the United States.


Can marijuana be addictive?


Chronic marijuana use has been associated with the development of tolerance in which the user may have a tendency to increase the amount of marijuana used. "Physical and psychological dependence in frequent users is associated with signs and symptoms of withdrawal upon discontinuation," according to Wadler. "These signs and symptoms begin about 10 hours after discontinuation and peak at 48 hours and include anxiety, insomnia, sweating, loss of appetite and craving for THC." According to a report from the Substance Abuse and Mental Health Services Administration (SAMHSA), almost 196,000 people entering drug treatment programs reported marijuana as their primary drug of abuse, indicating that they needed help to stop using the drug.


What are the long-term adverse health effects of marijuana?


"Because marijuana users often inhale the unfiltered smoke deeply and then hold it in their lungs as long as possible, chronic marijuana use may play a role in the development of chronic respiratory problems," says Wadler. Animal studies have suggested that THC may adversely affect the immune system. Additionally, long-term use has been associated with motivational problems including apathy, impaired judgment, loss of ambition and an inability to carry out long-term plans.
