People who usually take Crystal Meth seek the pleasure from the chemical reaction in the brain and a hyper effect on the body systems. People who use Crystal Meth will experience hyper activity and won’t be able to properly sleep and will become lazy. People who take Crystal Meth appear normal, but for many years of taking the drug, the hidden effects build up. Methamphetamine addiction is very damaging to the body and mind. Bad temper and social difficulties are obvious effects.
As a result, dopamine binds again and again to the receptors overstimulation the cell. Like other drugs, cocaine concentrates in the reward pathway. However, it is also the reward pathway. However, it is also active in the part of the brain controlling voluntary movements. This is why cocaine abusers are fidgety and unable to be
nor adrenaline and serotonin mainly. These neurotransmitters act like chemical messages in the nervous systems and are known to be active in parts of the brain associated with reward and punishment. They help to regulate the hypothalamus which is involved in sleep appetite , sexuality and physical movement., and these key areas are affected in depressive disorders. Support for this explanation has come from drug therapy. Anti depressants such as MAOI’s which increase the available amount of nor adrenaline in the brain, were found to be effective for elevating the symptoms of depression.
Bad moods can also be intensified by using this stimulant ( Parrot 45 ). Chronic use can result in violent behaviors, anxiety, depression, confusion, hallucinations, delusions, and paranoia. When the addict stops using the drug, these side effects are more severe. Brain damage caused by meth abuse is similar to Alzheimer’s disease and epilepsy ( USDOJ “Meth…” ). These moods and behaviors can lead to social and occupational deterioration ( NIDA “Meth…” ).
Networks of neurons pass messages back and forth to different structures within the brain, the spinal column, and peripheral nervous system. Drugs are chemicals that work in the brain by tapping into the communications system and interfering with the way nerve cells normally send, receive, and process information. Nearly all addictive drugs stimulate the brains reward circuitry, producing felling of pleasure (Kalat, 2009). Some drugs, such as marijuana and heroin can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This similarity in structure “fools” receptors and allows the drugs to lock onto and activate the nerve cells.
It is used in post surgery as well as common pain relief. Vicodin® acts as a block in the central nervous system. This can cause it to be very lethal if overdosed, causing the central nervous system to completely shut down. Its purpose is to block signals of pain being delivered to the brain. Vicodin®, because of its “mellowing” properties, can become highly addictive and is why it is among hundreds of abused narcotics
It can be injected, snorted, sniffed, or smoked. All these ways rapidly deliver the drug to the brain. Some younger users try to avoid injection because it “looks bad” but after a while they end up using that method because their bodies are becoming conditioned to the drug, and injection gives a more intense effect.

Psych 213 Dr. Les White April 9, 2012 Major points the article covers or raises “The Addicted Brain,” by Nestler and Malenka discussed the brain’s memory of addiction which results from repeated use and subsequently abuse of drugs and alcohol. While very technical and scientific in its detailing of the processes, it was also very insightful in spelling out the brains rewarding of the pleasure that results from drugs of abuse (DOA). It seems that we have known for quite a while why someone feels good when they use DOA, but the article points out that new research is just beginning to understand some of the resulting long term changes in the brain. Even though the pleasurable effects of using a particular drug aren’t as strong as they
Most individuals who find themselves addicted to illicit drugs will need help to “kick the habit,” and they may find themselves in a court appointed rehabilitation program. There are many programs and treatments that are
Activists on Prescription Drug Abuse Around the world there are so many teens looking to get drugs. A big part of them abuse prescription drugs for a non-medical purpose to alter the way they think or use their mind, and it can even leave them in a dependent state (NIDA, 2008). They choose most prescription drugs mainly for how accessible they are. They go into any drug store and can pick up even a cold medicine to go on a trip. The reason it is such a big problem is because it can lead to over dosing and possible dying.
