Marijuana Effects on the Brain

Marijuana is the most consumed and the most illegal drug. It contains a psychoactive ingredient called tetrahydrocannabinol or THC responsible for the “high” you get when this drug is consumed. It travels throughout the body, including the brain and gets stored in the body fats. THC, when it gets to the brain, can produce different side effects. Find out what they are and how it can be eliminated.

Mechanism of marijuana in the body:

  • Once marijuana is inhaled, smoked or ingested, the THC travels through the bloodstream and to the rest of the body including the brain and immune system tissues.
  • They bind to receptor sites called CB1 and CB2. CB1 is responsible for memory, coordination, movement, mood, and appetite.
  • While the CB2 travels through the immune system tissues like lymph nodes and spleen.

Side effects of Marijuana in the brain

  • Marijuana can alter perceptions, impaired coordination. There is difficulty in concentration, thinking and learning, decreased short-term memory and difficulty in problem-solving
  • Long-term use of marijuana can lead to addiction and compulsive drug-seeking.
  • Withdrawal from marijuana use can often lead to irritability, anxiety, insomnia and decreased appetite. These symptoms usually occur a day after quitting and may last for 2-3 days and gradually tapers down after deciding to quit.
  • Effects are often life-threatening with chronic marijuana use. The user may have suicidal tendencies, increased levels of anxiety and depression. Some may even suffer from a mental disorder like schizophrenia and other psychotic reactions.

Large longitudinal study conducted in New Zealand, which found that frequent and persistent marijuana use starting in adolescence was associated with a loss of an average of 8 IQ points measured in midadulthood. Significantly, in that study, those who used marijuana heavily as teenagers and quit using as adults did not recover the lost IQ points.


Marijuana’s adverse reactions to health

  1. A marijuana abuser may likely increase the risk of getting a heart attack an hour after smoking the drug because of its effect on the blood pressure and heart rate. It hinders the blood’s capacity to carry oxygen-rich blood through all parts of the body.
  2. For marijuana smokers, their lungs are much affected by smoking the drug. This may lead to a chronic cough, excessive phlegm production, frequent acute chest illness, high-risks for lung infections and obstructed airways.
  3. Marijuana, when used during pregnancy, may cause neurobehavioral problems among infants. THC may alter the baby’s brain development. It may include attention deficit disorders, problems with memory and problem-solving.
  4. Among men, heavy marijuana use can cause a decrease in testosterone levels, low sperm count, decreased libido and impaired fertility.
  5. Marijuana can also cause complications in pre-existing liver diseases, hypertension, and diabetes.
  6. Studies may not yet prove it, but there seems to be a link between lung cancer and heavy use of marijuana through smoking, as the effect on the lungs is similar to that of a tobacco smoker.

In one study, it was estimated that marijuana users have a 4.8-fold increase in the risk of heart attack in the first hour after smoking the drug.


Note: Knowing what marijuana does to your brain and health, it is best to stop taking the drug completely. But that can be daunting, especially if you are a chronic marijuana user who finds solace in the drug. Good thing there are ways on how to rid your body of THC effectively.
