Reviews There are no reviews yet. Crystal meth is most commonly smoked in glass pipes, but it can also be snorted, injected, swallowed, or inserted into the anus or the urethra.
Crystal meth boosts the release and stops the reuptake of a neurotransmitter, or brain chemical, called dopamine. In this way, it increases the levels of dopamine in the body.
Dopamine plays an important role in motor function, motivation, reward, and how the brain experiences and interprets pleasure.
Taking crystal meth causes dopamine to build up in the brain. This is a common feature of many abused drug.
Abusing crystal meth can lead to considerable changes in brain function. Crystal meth can also severely affect the structure and function of brain areas linked to emotion and memory.
This may explain why chronic users of crystal meth often develop emotional and cognitive difficulties. Some brain changes that occur remain long after the user has stopped taking the drug.
Some may reverse after long periods of abstinence, but this could take a year or more. When taken regularly or in high doses, crystal meth can cause a condition known as methamphetamine psychosis.
Chronic use or overdose can lead to convulsions, stroke , heart attack , and death. Regular users of crystal meth have a significant risk of losing their teeth through severe decay.
This is known as meth mouth. One reason is that methamphetamine contains acid ingredients that are bad for the teeth. Illicit products may include drain cleaner, battery acid, and hydrochloric acid.
Crystal meth produces feelings of euphoria for up to 12 hours, and users crave its powerful effect again and again.
Symptoms can last for days or weeks, depending on how long the addiction has lasted. Drug rehabilitation programs can help people through the withdrawal process and guide them toward a drug-free life once withdrawal symptoms have gone.
There is currently no government-approved drug that can help a person recover from crystal meth addiction. Treatment may involve cognitive behavioral therapy CBT , exercise, and nutritional guidance and incentives, such as vouchers, in exchange for remaining drug-free.

Neuroimaging studies have revealed that METH can indeed cause neurodegenerative changes in the brains of human addicts Aron and Paulus, ; Chang et al.
These abnormalities include persistent decreases in the levels of dopamine transporters DAT in the orbitofrontal cortex, dorsolateral prefrontal cortex, and the caudate-putamen McCann et al.
The density of serotonin transporters 5-HTT is also decreased in the midbrain, caudate, putamen, hypothalamus, thalamus, the orbitofrontal, temporal, and cingulate cortices of METH-dependent individuals Sekine et al.
Neuropsychological studies have detected deficits in attention, working memory, and decision-making in chronic METH addicts There is compelling evidence that the negative neuropsychiatric consequences of METH abuse are due, at least in part, to drug-induced neuropathological changes in the brains of these METH-exposed individuals These include loss of gray matter in the cingulate, limbic and paralimbic cortices, significant shrinkage of hippocampi, and hypertrophy of white matter Thompson et al.
Elevated choline levels, which are indicative of increased cellular membrane synthesis and turnover are also evident in the frontal gray matter of METH abusers Ernst et al.

Advances in Pharmacology. Glia including astrocytes, microglia, and oligodendrocytes , which constitute the majority of cells in the brain, have many of the same receptors as neurons, secrete neurotransmitters and neurotrophic and neuroinflammatory factors, control clearance of neurotransmitters from synaptic clefts, and are intimately involved in synaptic plasticity.

Dialogues in Clinical Neuroscience. Despite the importance of numerous psychosocial factors, at its core, drug addiction involves a biological process: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction.
Moreover, there is increasing evidence that, despite a range of genetic risks for addiction across the population, exposure to sufficiently high doses of a drug for long periods of time can transform someone who has relatively lower genetic loading into an addict.

Substance-use disorder: A diagnostic term in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders DSM-5 referring to recurrent use of alcohol or other drugs that causes clinically and functionally significant impairment, such as health problems, disability, and failure to meet major responsibilities at work, school, or home.
Depending on the level of severity, this disorder is classified as mild, moderate, or severe. Addiction: A term used to indicate the most severe, chronic stage of substance-use disorder, in which there is a substantial loss of self-control, as indicated by compulsive drug taking despite the desire to stop taking the drug.
In the DSM-5, the term addiction is synonymous with the classification of severe substance-use disorder. This is known to occur on many genes including fosB and c-fos in response to psychostimulant exposure.
Chronic exposure to psychostimulants increases glutamatergic [signaling] from the prefrontal cortex to the NAc.
The Journal of General Physiology. Coincident and convergent input often induces plasticity on a postsynaptic neuron.
The NAc integrates processed information about the environment from basolateral amygdala, hippocampus, and prefrontal cortex PFC , as well as projections from midbrain dopamine neurons.
Previous studies have demonstrated how dopamine modulates this integrative process. For example, high frequency stimulation potentiates hippocampal inputs to the NAc while simultaneously depressing PFC synapses Goto and Grace, KEGG Pathway.
Retrieved 31 October Most addictive drugs increase extracellular concentrations of dopamine DA in nucleus accumbens NAc and medial prefrontal cortex mPFC , projection areas of mesocorticolimbic DA neurons and key components of the "brain reward circuit".
Amphetamine achieves this elevation in extracellular levels of DA by promoting efflux from synaptic terminals.
Chronic exposure to amphetamine induces a unique transcription factor delta FosB, which plays an essential role in long-term adaptive changes in the brain.
Molecular Neurobiology. Nature Reviews Neuroscience. The net result is gene activation and increased CDK5 expression.
The net result is c-fos gene repression. Clinical Psychopharmacology and Neuroscience. Drug Alcohol Abuse. Similar to environmental enrichment, studies have found that exercise reduces self-administration and relapse to drugs of abuse Cosgrove et al.
There is also some evidence that these preclinical findings translate to human populations, as exercise reduces withdrawal symptoms and relapse in abstinent smokers Daniel et al.
In humans, the role of dopamine signaling in incentive-sensitization processes has recently been highlighted by the observation of a dopamine dysregulation syndrome in some patients taking dopaminergic drugs.
This syndrome is characterized by a medication-induced increase in or compulsive engagement in non-drug rewards such as gambling, shopping, or sex Evans et al.
Archived from the original on 13 October Bibcode : PNAS.. Journal of Psychoactive Drugs. It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward.
Pitchers and colleagues reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus.
Drugs of abuse induce neuroplasticity in the natural reward pathway, specifically the nucleus accumbens NAc , thereby causing development and expression of addictive behavior.
Sexual behavior is highly rewarding Tenk et al. Moreover, sexual experience induces neural plasticity in the NAc similar to that induced by psychostimulant exposure, including increased dendritic spine density Meisel and Mullins, ; Pitchers et al.
Finally, periods of abstinence from sexual experience were found to be critical for enhanced Amph reward, NAc spinogenesis Pitchers et al.
