Methylenedioxymethamphetamine (MDMA) (3,4-methylenedioxymethamphetamine) is an empathogenic drug of the phenethylamine and amphetamine classes of drugs. Amphetamines and phenethylamines are a class of chemicals/drugs that are synthetic, psychoactive drugs. Many are sympathomimetics and central nervous system stimulators causing excitation, vasopressin, bronchodilation, and to varying degrees, anorexia, analepsis, nasal decongestion, and some smooth muscle relaxation. In 1985, the US Drug Enforcement Administration moved the drug to Schedule 1 status with no accepted medical use. Source: Regenstrief LOINC, MDMA

Methamphetamine (MA) is a drug of abuse also referred to as meth, crystal and speed. It is a central nervous system stimulant that can be injected, smoked, snorted or ingested. Short-term MA abuse causes an increase of energy, sense of well-being and decreased appetite that lasts 6-8 hours. PMID: 19042205 MA use can lead to stroke, cardiac arrhythmia, stomach cramps, shaking, anxiety, insomnia, paranoia, hallucinations, and structural changes to the brain. Pregnant women who use MA can cause growth retardation, premature birth, and developmental disorders in neonates and long lasting intellectual deficits to the children as they grow. PMID: 10908000 Users addicted to MA experience withdrawal symptoms that include dysphoria, fatigue, insomnia and an increased appetite. In chronic MA users positron emission tomography has proven a decrease in dopamine D2 receptors which is associated with mental deterioration that can be reversed to some extent after abstaining from MA.
