It is no news that smoking and inhaling harmful substances are by far dangerous to our health. Below are some of the systems in our which could be weakened if we smoke so often.
THC means Tetrahydrocannibol.
- Respiratory System
Much like tobacco smoke, marijuana smoke is made up of a variety of toxic chemicals that can irritate your bronchial passages and lungs. If you’re a regular smoker, you’re more likely to wheeze, cough, and produce phlegm.
You’re also at increased risk of bronchitis and lung infections. Marijuana may aggravate existing respiratory illnesses like asthma and cystic fibrosis.
Marijuana smoke contains carcinogens. It has the potential to elevate your risk of developing lung cancer. However, studies on the subject have had mixed results. According to the National Institute of Drug Abuse (NIDA), there is no conclusive evidence that marijuana smoke causes lung cancer. More research is needed.
- Circulatory System
THC moves from your lungs into your bloodstream and throughout your body. Within minutes, your heart rate may increase by 20 to 50 beats per minute, according to the NIDA .
That rapid heartbeat can continue for up to three hours. For people with heart disease, this faster heartbeat could raise the risk of heart attack.
One of the telltale signs of recent marijuana use is bloodshot eyes. They look red because marijuana causes blood vessels in the eyes to expand or dilate. Marijuana may help stop the growth of blood vessels that feed cancerous tumors.
- Central Nervous System
When you inhale marijuana
smoke into your lungs, it doesn’t take long for THC to enter your bloodstream. From there, it is quickly transported to your brain and the rest of your organs. When you get marijuana from food or drink, it is absorbed a little more slowly.
THC triggers your brain to release large amounts of dopamine, a naturally occurring “feel good” chemical. That’s what gives you a pleasant “high.” It may heighten your sensory perception, as well as your perception of time.
In the hippocampus, THC changes the way you process information, so your judgment may be impaired. It may also be difficult to form new memories when you’re high.
Changes also take place in the cerebellum and basal ganglia, upsetting your balance, coordination, and reflex response. All those changes mean that it’s not safe to drive.
Very large doses of marijuana or high
concentrations of THC can cause
hallucinations or delusions. According to the NIDA , there may be an association between marijuana use and some mental health problems like depression and anxiety, but more research is needed to understand the connection. In people who have schizophrenia, marijuana use can make symptoms worse.
When you come down from the high, you may be tired or feel a bit depressed. In some people, marijuana can cause anxiety. About nine percent of marijuana users develop an addiction, according to the NIDA . Symptoms of withdrawal may include irritability, insomnia, and loss of appetite.
In young people whose brains are not yet fully developed, marijuana can have a lasting impact on thinking and memory skills. If you use marijuana when pregnant, it can affect the brain of your unborn baby. Your child may be more prone to trouble with memory, concentration, and problem-solving skills.
THC can lower pressure in the eyes, which can ease symptoms of glaucoma for a few hours.
According to the American Academy of Ophthalmology , more research is needed to understand the active ingredients in marijuana and whether or not it’s a good treatment for glaucoma.
The pharmacologic effect of marijuana extends throughout the central nervous system. It is thought to ease pain and inflammation. It may also be of use in controlling spasms and seizures.
- Digestive System
Smoking marijuana can cause
stinging or burning in your mouth and throat. When you take oral THC, it is processed in your liver. Marijuana can ease nausea and vomiting. It can also increase appetite, which can be useful to people living with cancer or AIDS.
- Immune System
Some research indicates that THC affects the immune system. Studies involving animals showed that THC might damage the immune system, making you more vulnerable to illness.
