Crystal Meth
The powerful thrill that people get from using Methamphetamine gets many hooked. When used, a chemical called dopamine floods the parts of the brain that regulate the sensation of pleasure. As a result, users also feel confident and energetic.
A user can quickly become addicted and soon discover that they will do anything to get back in a hurry. As they continue to use the drug, they develop tolerance. That means they need higher doses to get the same effect. The higher the dose, the greater the risks. Learn more about how methamphetamine use affects the body.

The newest or most recent form of crystal methamphetamine is nearly 100% pure. It is odourless and can be smoked in glass pipes. Research shows that it is more addictive than crack and cocaine and even more deadly. Depending on the individual, its effect can last from 4 to 14 hours in the system. During this period, smokers feel an intense mental and physical euphoria rush—a good feeling. However, your intense feeling of depression, anxiety, insomnia, and eventual fatigue will result from a heavy short. Although you can buy Methamphetamine without a prescription, it is important to know that long-term use damages the liver, lungs, and kidneys. Therefore, you need to monitor your dose.

Like other stimulants, such as coke or cocaine, crystal methamphetamine acts on the level of dopamine in the brain. It also provides an additional norepinephrine-mimicking kick. So what happens is that the neurons release more of both in the meantime, training the brain to need more to survive. Methamphetamine withdrawal or hangover can last for days and break the individual's mental and physical stability. Therefore, when you buy Methamphetamine online, you should be aware of these effects. Other street names are rock, LA glass, super ice or hot ice, and Hawaiian salt. Ketamine is also available here.

The white crystals of Methamphetamine are not a new invention. Quite the contrary. The first to produce the psychoactive liquid (S)-N-methyl-1-phenyl propane-2-amine was the Japanese chemist Nagayoshi Nagai in 1893. In the 1920s, chemists crystallized with the help of hydrochloric acid, the solid substance known today in English as crystal meth: methamphetamine hydrochloride in crystalline form.
With the development of hydrochloride, the substance gained medical utility. And military: Wehrmacht soldiers took Methamphetamine, which they called " panzer chocolate ", during the blitzkrieg on the Western Front. After the war, the substance continued to be widely available, among other things, as a medicine against depression and obesity. After that, however, it spread mainly as a form of doping, at work or in sports. It was banned in the United States in 1970 but remained available in Germany, for example, under the trade name Pervitin until 1988.
Methamphetamine is very simple structurally. It has a 'stereocenter': the parts of the molecule can be arranged around this centre in two ways that are chemically identical but spatially mirror images of each other. Therefore, there are two mirror variants of the substance, one of them (S)-N-methamphetamine, with a more significant effect than the other, (R)-N-methamphetamine, and that is why it is usually manufactured preferably preferably preferably manufactured. However, making that most desired variant is considerably more difficult than mixing the two variants. Therefore, illegally manufactured Methamphetamine generally consists of both forms, unless the starting material is ephedrine.
How does (S)-N-methamphetamine work in the body?
Methamphetamine is a stimulant for the body and mind: users report a real energy rush, euphoria, and heightened libido. On the other hand, it suppresses the feeling of hunger and increases the heart rate and blood pressure. Prolonged use creates dependence on Methamphetamine.
As a small, well-lipid-soluble molecule, it crosses the blood-brain barrier and easily penetrates the brain. There it increases the concentration of the neurotransmitters serotonin and dopamine outside the neurons for reasons not yet fully explained.
It seems that the molecule inverts the functioning of the neurotransmitter transporters in cell and vesicular membranes: it causes these messenger substances to reach the cell plasma from the synaptic vesicles (which normally, under the effect of nerve impulses, trigger neurotransmitters to the synapse), and from there, the transporters that normally return dopamine to the nerve endings carry that transmitter from the cell interior to the exterior, thereby increasing the concentration of neurotransmitters in the synaptic cleft. Over time, neurotransmitters in neurons are depleted. Both effects together cause the desired and undesired symptoms. In this way, Methamphetamine interferes with reuptake and leads to more firing of nerve cells.
Its effect, not without risk, on the heart and circulatory system is probably due to the release of norepinephrine by nerve cells in the central nervous system. The basis for the psychological effects and efficacy of amphetamines in treating attention deficit hyperactivity disorder is not clear. The researchers hypothesize that activation of the noradrenergic system in the brain also plays a role here. In addition, opioid receptor antagonists block some effects of Methamphetamine, suggesting some involvement of the body's opiates.
Can the substance be legally acquired?
Today, (S)-Methamphetamine is still available as a drug for attention deficit hyperactivity disorder and morbid obesity. (R)-Meth, on the other hand, is available over the counter in the form of nasal sprays; in modest concentrations, it serves to deflate the nasal mucosal lining. However, these drugs are considered too risky compared to their usefulness, given the dangers of methamphetamine use.
What harm do methamphetamine preparations cause?
Methamphetamine has a number of harmful side effects, especially at high doses. An acute overdose manifests itself in a kind of exalted delirium with nausea, tachycardia, panic attacks, and other symptoms. An acute rise in blood pressure and heart rate can lead to life-threatening complications or cardiac arrest. Kidney failure, brain haemorrhages, and other strokes are known causes of death related to methamphetamine overdoses.
More often than not, long-term regular use has negative consequences. Over time, Methamphetamine becomes addictive. Research indicates that a lack of dopamine in the brain's striatum is to blame: Methamphetamine releases dopamine from nerve cells. Hence, the supply quickly runs out (Information on this can be found on pages 349-358 of the manual to which this link refers). In high doses, the substance durably dulls the presynaptic axon endings in the striatum, responsible for transmitting nerve signals, which is thought to contribute to addiction and possibly make withdrawal symptoms last longer. Addiction researchers are thoroughly studying the role of dopamine in that region of the brain; the connections are not entirely clear today. For example, it remains uncertain whether the effect on the striatum is due to nerve cell death or altered dopamine endowment.
A long-lasting reduced dopamine content in the striatum is also found in Parkinson's patients. As recent research has shown, methamphetamine use significantly increases the risk of Parkinson's disease over the years. Contrary to amphetamine, a chemical related to Methamphetamine, it is toxic to nerve cells; Methamphetamine may activate the apoptotic signalling pathway, thereby triggering programmed cell death.
Methamphetamine also appears to cause long-term damage to other organs, especially the cardiac-circulatory system. Data shows that regular use significantly increases the risk of atherosclerosis and other blood vessel diseases and affects the heart. The researchers assume that the risk of heart attack rises accordingly.
A considerable part of methamphetamine users suffers from mental disorders and illnesses. According to a study carried out in the United States in 2004, a third of the users studied had been prescribed at least one psychotropic drug, and a quarter was subject to hospital treatment for mental illness. Psychoses, in particular, are more familiar with Methamphetamine than with other drugs and ten times more common than in the general population. Methamphetamine is also associated with depression and suicide attempts; According to research, between a quarter and more than half of users show associated symptoms.
Many specialists question an often-cited indirect detrimental consequence. Users would, it is said, have more cavities and lose teeth over time because the drug could cause dry mouth and teeth grinding (bruxism). At the same time, however, scientists are increasingly pointing out that prescription drugs with these same side effects do not lead to tooth loss.
How is methamphetamine hydrochloride made in the laboratory?
There are six pathways for the synthesis of methamphetamine salts. Two of them create a 1:1 mixture of the two enantiomers; they use phenylacetone, a common industrial chemical but are now subject to restrictions. It is only necessary to replace the oxygen in this compound with a methylamino group. For this, there are two very simple possibilities: one, reductive amination, which was almost the "classic method" of preparing the drug until the United States Government made it difficult much access to the necessary chemical substances, and on the other hand, the so-called Leuckart-Wallach reaction, with methyl formamide.
But the preferred ones, because they produce the desired form of Methamphetamine, are the synthesis routes that start from ephedrine and its relative pseudoephedrine. Both are natural substances originating from many species of the Ephedreceae plant family and included, for example, in medicines against rhinitis. However, ephedrine-based reactions require firefighters often discover more chemical reagents, so illegal meth labs.
The so-called Nagai route is named after Nagayoshi Nagai and, through modified versions, is today the best-known method. However, some variants of this reaction are dangerous because they can form white phosphorus and the highly poisonous phosphane gas, a reaction that the protagonist of the Breaking Bad series uses in the pilot episode to take down two enemy traffickers.
At least as dangerous is a procedure known in English-speaking countries as Shake `n` Bake (after the name of a batter product): bleach, ammonium nitrate, lithium, and lamp oil are used to hydrogenate the starting material. This procedure is known for its unwanted and violent side reactions.
