There are many ways Meth can be used, in which include smoked, injected, orally ingested, or snorted. When Meth is smoked or injected it causes more of a rush. When it is snorted or taken orally it produces a longer lasting high instead of a rush, which can continue for as long as twelve hours. Both the rush and the high result from the release of very high levels of dopamine into areas of the brain that regulate feelings of pleasure. This is why people become addicted.
Effect of alcohol: Alcohol has an impact on the dopamine, serotonin, endorphins, glutamate, and GABA neurotransmitters. Genetics influence people’s tendency toward alcohol dependency. Effect of Barbiturates: cause relaxation, some euphoria, and diminished attention. 14. Stimulant: increase behavioral and mental activity.
As with most illegal drugs, heroin use has both short-term and long-term effects. Whether injected, snorted or smoked, heroin will begin to affect the body's central nervous system almost immediately after it is used. Short-Term Effects Shortly after using, a feeling of euphoria will come over users, in which they have a warm flushing of the skin, a dry mouth and the feeling of having "heavy" arms and legs. After the initial rush, users will go into an alternately wakeful and drowsy state sometimes called "on the nod." Because heroin suppresses the central nervous system, the user experiences "cloudy" mental function.
* Depressants slow down the central nervous system and can reduce anxiety or emotional distress., examples include cannabis and barbiturates. * Opiates provide pain relief, induce euphoria, sedation and can lead to coma, examples include heroin, opium, methadone and morphine. * Hallucinogens induce an altered state of consciousness and effect perception of reality, examples include LSD and mushrooms. Prescription drugs containing opoids, benzodiazipines (which are depressants of the central nervous system) or stimulants can be misused when taken for reasons other than those they were prescribed for. Prescription drugs can cause sedation, altered state of consciousness, depressed respiration and changes in blood pressure.
Dopamine is a neurotransmitter which is correlated with learning, attention and movement. High levels of dopamine have been linked in schizophrenic symptoms. For example, the drug cocaine increases dopamine which trigger schizophrenic symptoms such as hallucinations. The dopamine hypothesis states that schizophrenics have too many dopamine receptors with neurons that transmit too many messages that fire too often. D2 receptors have been shown to play a key guiding role.
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.
Methamphetamine, like other drugs, is able to short-circuit the survival system by artificially stimulating pleasure areas in your brain. As this happens, it leads to increase confidence in meth, and less confidence in normal life routines. Usually when this occurs the addict will be more interested in meth related activities, meth related people, and meth related environments. Withdrawals of Meth Use: Fact or Fiction? Much to contrary belief meth users do suffer from withdraws as well as any other drug addict would.
In my Psychology book in one chapter it talked about the alcohol impairment and how it can then create bad judgment. Because alcohol acts to depress the reticular activating system, several things occur. The altering mechanism is depressed such that a person does not become aware of potentially hazardous or dangerous situations that the sensory functions detect. The sensory functions themselves are deteriorated and may not be supplying complete or correct information to the brain. A person's motor of functions is impaired; yet, because of alcohol's depressant effect that person will feel less inhibited and more self confident about themselves.
It may offer reduced memory loss and a reduction in hallucinations. Medication can have a calming effect and helps enable sleep. It can help reduce the likeliness of the person concerned to worry and reduce their pain. Along with this, medication can also reduce aggression and restlessness. Some of the negative effects are things such as nausea and stomach pains, restlessness and tiredness.
Impaired judgments due to decreased levels of inhibitions can lead to risky sexual activity. As well, those users that use intravenously increase their chances of contracting HEP B or C or HIV/AIDS. Crystal methamphetamine is not necessarily an aphrodisiac, but through increasing the level of dopamine through triggering the release of powerful brain chemicals, it may increase sex drive. Ironically, while desire and stamina are increased, it ultimately decreases the users’ sexual desirability and performance (PBS, n.d.). 6connected with the fact that crystal meth can suppress one’s appetite.
