Answer 2

Methamphetamine is closely related chemically to amphetamine, but the central nervous system effects of methamphetamine are greater. Both drugs have some medical uses, primarily in the treatment of obesity, but their therapeutic use is limited.

Methamphetamine (Meth) is an addictive stimulant that strongly activates certain systems in the brain and speeds up the body's central nervous system. It was originally marketed as a nasal decongestant and is currently used medically in the U.S. for treating obesity. It rapidly enters the brain and causes a cascading release of norepinephrine and dopamine (and to a lesser extent, serotonin) resulting in euphoria and the availability of undirected energy.

Methamphetamine is classified as a psychostimulant, as are other drugs of abuse such as amphetamine and cocaine. We know that methamphetamine is structurally similar to amphetamine and the neurotransmitter dopamine, but it is quite different from cocaine.

Although these stimulants have similar behavioral and physiological effects, there are some major differences in the basic mechanisms of how they work at the level of the nerve cell. However, the bottom line is that methamphetamine, like cocaine, results in an accumulation of the neurotransmitter dopamine, and this excessive dopamine concentration appears to produce the stimulation and feelings of euphoria experienced by the user.

In contrast to cocaine, which is quickly removed and almost completely metabolized in the body, methamphetamine has a much longer duration of action and a larger percentage of the drug remains unchanged in the body.

This results in methamphetamine being present in the brain longer, which ultimately leads to prolonged stimulant effects.


As a powerful stimulant, methamphetamine, even in small doses, can increase wakefulness and physical activity and decrease appetite. That is why people do not eat when they have taken methamphetamine.

Answer 3

You asked two important questions. Briefly I will tell you the ans were to number one. This addiction starts in the brain. The brain has neurotransmitters which is the messenger between brain cells. Then you have other chemicals naturally occurring in your brain, like serotonin which controls mood and another for pain and so on. Often drugs take this place as a feel good drug and messes up the serotonin and natural pain killing chemicals in your brain and will leave a person very depressed when it wares off, often leaving them to think they need more, when the drug will only make it all worse. The second question is about not being hungry is one I dk remember, but my best guess would be it is like anesthesia and no one feels like eating when they feel no pain, but personally I don't know because I have never used the drug, though I have understanding about what it does to the brain's serotonin level. It is much like what someone on cocaine will experience.

Answer 4

There are tons of harmful chemicals in methamphetamine and most people get addicted to it because of the effects it has on your body and mind. While under it most will feel a sort of "On top of the world" feeling, but it is really just damaging brain cells.

As for the not eating, if they ade addicted to this drug, their mind will always be on it (Ex. when theyll have it again, where theyll get it) and this distracts them from actually doing normal things that are important. It can also be due to Brain damage. You cant control the part of your brain being damaged so it could shut off the part that tells you to eat, or even the part that says go to the bathroom, which would leave you soiling yourself in public.
Hope this helps?

Answer 5

It's addictive because it causes euphoric effects. The body's nervous system becomes accustomed to the presence of these chemicals, and may slow/stop production of certain neurotransmitters. If the methamphetamine is stopped, the person's nervous system takes a 'dive', and taking more meth is the only way (to them) to be normal.

People also snort, inject (aka slamming), or smoke meth. This is because these methods allow the effects to be experienced more quickly, without much waiting.

Answer 6

Meth is a stimulant, just like nicotine and caffeine... most, if not all pharmaceuticals that end with -ine are stimulants.

They tend to cause an individual to feel an increased, if not intense, increase in energy and power, improve focus and concentration, and suppress one's appetite. Their effects help people cope with issues such as having too many tasks and too little time, focusing on exams/work, and loosing weight. It is not hard to see how/why an individual could quickly become addicted to such drugs for the "benefits" they provide.

Once a person has used such substances for a significant period of time, certain neural receptors may begin to shut down, as the stimulant fulfills their function. Before long, one's body actually begins to anticipate and expect to thrive from the benefits of the drug.

If meth and/or other stimulants are discontinued abruptly, one's body goes through a period of withdrawl, as the individual waits for his/her neural receptors to compensate for the absence of the drug.

Answer 7

It affects the brain cells and modify it in some way that they demand for it if you quit , just like any other addictive substance, smoking for example..it gives a sensation of satiety..but it is a seriously destructive substance to all body organs, tis a poison, it also affect the mental and behavioral fuctions, and highly increase criminal activities, it is a very big social problem nowadays unfortunately!!

Answer 8

No people smoke it, and the main reason why is if you stop, you'll be really really tired for the next 5 days or so.
