It can damage your brain in many ways.  Seazures and cadiac complications from GHB leading to hypoxia (lack of Oxygen) or even death are not uncommon. If your brain goes without oxygen for even a short time profound and irreversable brain damage can occure\n\nMany studies have found GHB and other related drugs when used over time can lead to destuction of neural pathways in the brain.  There is also an increased risk of stroke, asperation and resulting hypoxia, head or injury due to CNS depression, risky or dangerous behavior resulting in serious injury due to decreased coginitve function and perception. \n\nThe margen of saftey is very small with GHB and since it is  illegal in the US for all but a very, very small groupe of rare narcoleptics, any GHB gotten from street sources varies widly in quality, dosage and purity.  Many substances used to cut or increase the effects of the street product can be as harmful or even more harmful to your brain than the GHB its self. Some of these contaminants or additives also greatly increase the risk of seazures and other serious life treatening complications of the GHB.

Mercury is a heavy metal and is very harmful to the environment and the body.  It can cause nerve damage as well as damage to a fetus.  It can contaminate both soil and water.\n\nMercury is a liquid at room temp. so it can be absorbed through the skin.  The usual method of mercury poisoning is through eating contaminated foods. I've not heard of mercury gas poisoning, but, I wouldn't want to be near a chemical spill that involved mercury gas.

Methamphetamine affects your brain. In the short term, meth causes mind and mood changes such as anxiety, euphoria, and depression. Long-term effects can include chronic fatigue, paranoid or delusional thinking, and permanent psychological damage.\n\nMethamphetamine affects your body. Over “amping” on any type of speed is pretty risky. Creating a false sense of energy, these drugs push the body faster and further than it's meant to go. It increases the heart rate, blood pressure, and risk of stroke.\n\nMethamphetamine affects your self-control. Meth is a powerfully addictive drug that can cause aggression and violent or psychotic behavior.\n\nMethamphetamine is not what it seems. Even speed drugs are not always safe. Giga-jolts of the well-known stimulants caffeine or ephedrine can cause stroke or cardiac arrest when overused or used by people with a sensitivity to them.\n\nMethamphetamine can kill you. An overdose of meth can result in heart failure. Long-term physical effects such as liver, kidney, and lung damage may also kill you.\n\nThere are many places to get free help and support.

For starters it affects your hair a persons internal organs and not to mention the thinking, memoryloss and it causes a person's body to shut down, in a nut shell it starts to kill you because a person needs food for fuel and the exstreem can really damage the body in a way that impairs a younger from growing into a mature adult.

Alcohol affects all neuro- transmission... not the hormone itself. Drinking alcohol is like drinking gasoline, the brain considers it a toxin and the body focuses on ridding itself of that toxin. If the individual pauses drinking and the soberiety catches up all systems are normal again minus some water for cellular transport. I do not see how a hormone can be depleted by drinking alcohol.

It kills brain cells but you should have more than enough extra ones that it doesnt seem to concern too many people.  When your body metabolizes the alcohol, it turns it into liver fat and over a long period of time can decrease your body's ability to filter your blood through the liver.  It also dehydrates you and this is bad if you are an athlete.  In moderation, your body can deal with most of the bad stuff.

Chrystal meth produces schizophrenia-like symptoms due to it's effect on the dopamine receptors. However, unless you are genetically vulnerable to the disorder and the STRESS of taking a stupid recreational drug creates trauma, these effects should be only temporary

You lose brain cells every day without anything happening at all. Various things such as smoking, drinking alcohol or taking drugs, OR being hit in the head hard enough to sustain a concussion, will accelerate brain cell loss. \n\nBut just like with the rest of your body, you also grow new brain cells every day. Therefore, if you get hit in the head and are experiencing some thinking problems-- lack of memory, concentration, etc.-- you will PROBABLY get back most or all of your brain function as long as you don't do anything to aggravate the situation. Thinking problems related to getting hit in the head are more likely caused by pressure from bruising or swelling against the brain, and not actual "loss" of brain cells.

1)  The hormone is growth hormone (GH) , pressure in the head is caused by increased skull thickness, which is a result of the pituitary tumor secreating too much GH.  The visual disturbances are caused by the enlarged pituitary (from the tumor) compressing the optic chiasm.  \n\n2) So hypothalymus hormones can go directly to the anterior pituitary (rapido action as dr. guru pattar says) without circulating throughout the whole body.

The part of the brain called the cerebellum is at the base of the brain and the top of the spinal cord.  This part of the brain governs all the autonomic body functions... breathing, heart beat, many other automatic body functions.  You neighbor may have had a heart beat when he left your presence, but if he was "brain dead" it would not be too much longer when his heart would have stopped beating and his breathing also stopped.  It is the brain that governs your body functions... that is why drugs are such a threat to use... as they attack this part of the brain and eventually kills the person... A normal drug dose amount used one day and again used the next day just may become an OD amount of drug that will damage the brain to the point it will not recover... it will be the killing dose... One never knows...
