Marijuana and the Brain - Effects of Marijuana Use on the Body

Using marijuana can impair momentary memory, verbal abilities, decision, distort perception, and impair driving performance. Heavy marijuana use impairs a persons ability to create memories, remember occasions, or shift focus from 1 thing into another. Users that have taken high doses of this medication may experience severe toxic psychosis, including hallucinations, delusions, and depersonalization (a lack of this sense of personal identity or self-recognition).

In a couple of minutes a people heart begins beating more quickly, the bronchial passages unwind and become enlarged, and blood vessels in the uterus enlarge. The heart rate may rise by 20 to 50 beats per minutes. In the mind, the THC links to cannabinoid receptors on nerve cells and influences the activity of these cells. The effects start immediately and may last from 1 to 3 months. A marijuana user can experience agreeable sensations, colours and sounds may seem to be more extreme, and time appears to pass very slowly. The consumers mouth feels dry, and they may suddenly become quite thirsty and hungry. The hands will tremble and grow cold. The chills passes after awhile and the consumer may feel tired or depressed. Sometimes, marijuana use produces anxiety, fear, uncertainty, or anxiety. THC also interrupts balance and coordination by binding to receptors in the cerebellum and basal ganglia, the areas of the brain which govern balance, posture, coordination of movement, and response time.
