    What are the long term effects of smoking weed?

    Cannabis sativa or the Indian hemp plant is the source of cannabis preparation. The common names for cannabis are marijuana, grass, pot, weed, tea, and Mary Jane. It is one of the most common illicit drugs used all over the world. All parts of this plant are used as they contain the active ingredient called tetrahydrocannabinol. The cannabis plant is usually cut, dried, chopped and rolled into cigarettes which are then smoked. 


    Weed contains about 400 different chemicals. Out of these, 60 are related to tetrahydrocannabinol. These chemicals act on the cannabinoid receptors in the brain. They are mainly present in basal ganglia, the hippocampus and the cerebellum in brain. Smoking weed results in euphoria. Smoking weed is a major health risk. In a scientific survey involving 90 million adults who had used marijuana at least once in their lifetime, it was found that about 53 percent used the drug between age 12 and 17 and about 45 percent after age 18. Despite popular belief, marijuana is addictive.

    Effects of long term weed smoking

    Respiratory system: It contains same cancer causing chemicals which are present in tobacco. This increases the risk of chronic respiratory disease and lung cancer in heavy cannabis users. There is an increased incidence of emphysema of the lungs resulting in formation of air filled bullae. Chronic abuse of marijuana results in lowering of efficacy of immune cells in the lungs, resulting in higher risk of lung infections.

    Reproductive system: Chronic weed smokers have reduced sperm count in semen. It is associated with reduction in the testosterone levels in blood. In females, it affects the menstrual cycle by reducing the gonadotropic hormones. It increases the risk of infertility in both sexes. There is also an increased incidence of testicular cancer in chronic weed smokers. Non-seminomatous germ cell tumors of the testis have been reported. It is probably related to the presence of cannabinoid receptors in testis and also in these tumours.

    Pregnancy and lactation: Use of cannabis for many weeks during pregnancy was found to result in reduction in the length of gestation, though it did not affect the birth weight of the child. Exposure of infants to tetrahydrocannabinol present in breast milk was found to delay motor development at one year of age. This study was conducted at Department of Pediatrics, University of Washington, Seattle.

    Intelligence: A reduction in academic performance has been reported in college students after chronic abuse of marijuana. Cannabis can produce impairment in the higher cognitive functions like memory, attention and organization. There is also an impairment of the ability of brain to integrate complex information.

    Psychiatric illness: There is higher incidence of psychiatric impairment in people after prolonged use of weed. It may result in psychosis, manifesting as schizophrenia or bipolar disorder. An anxiety disorder may also occur, which is characterized by occurrence of panic attacks, which are based on ill-defined and disorganized fears. The appearance of anxiety symptoms is dose dependent. Chronic use is also associated with mood disorder presenting with depression.

     Sleep disorder: Sleep disorders have been reported in chronic smokers of weed. It reduces REM or ‘Rapid eye movement’ part of sleep which is associated with dreams. It resolves after cessation of its use.

    Amotivational syndrome: It is characterized by a reduction in persistence to perform a task. The person loses interest, becomes apathetic, and lacks energy and drive. There is an impairment of motivation and social performance.

    Chronic weed smokers are at increased risk of many diseases or disorders listed above. Majority of these addicts are young teens, who lose control and require proper guidance and protection. A positive support from the family and friends is required for treatment and prevention of failures.

    Okay, so, I have been on this Earth for quite a while and have had enough time to study and research this particular argument. And while I am not a scientist or medical professional, please allow me to articulate my opinion and findings in relation to this subject. First and foremost…..Anything, (be it smoke from any source or everyday dust particles) that you inhale, is not favorable for your lungs to process. Now, having said that…. 1) Tobacco is much worse for your respiratory system (as well as much more addictive) not on its own but because of other chemicals introduced by cigarette manufacturers (including Ammonia) in order to “enhance” and multiply the effects of tobacco and the chemical nicotine on the human body’s tolerance system. So, marijuana in its natural state is less addictive and less harmful (unless chemically enhanced or altered). As for memory loss, sperm counts, and the rest…..I can attest from personal experience (a long time ago) that pot can affect short term memory, as well it can cause a mellowness to behavior (while under its influence). But as far as long term affects, I can equally attest from personal experience that this is basely untrue. I have not ingested cannabis in any form for over 20 years, and rest assured, I still retain my memory, my health, and other faculties in spite of repeated use of pot in my youth. Now, I wonder how many drugs approved by the FDA and prescribed by “medical professionals” everyday could stand up to such scrutiny as marijuana? Just watch a commercial and listen to the “possible” side affects. Mark my words….when pot is legalized across the nation and the pharmaceutical industry can finally legally capitalize on its production and dispersion….you will see such companies singing the praises of this plant. Just my two cents.

        THANK YOU. This report goes to show how much fear mongering exists when you talk about marijuana. It’s not addictive? I agree with that- but everything has the potential to be a behavioral addiction; should we stop having sex? Spending all money? Stop washing our hands because it has the potential to become a compulsion? No – that’s downright absurd. Compare marijuana to AEDs, benzos, sleep aids etc., and if it stands up to the same scrunity as mentioned above, then we’ll talk. I’m glad I came across this article before reading many others on your site. For somebody who has a passion for the sciences (as I do myself) you don’t seem to be very insightful or educated.
