L\u2019amfetamina \u00e9s un tipus de droga estimulant del sistema nervi\u00f3s central. Es presenta en forma de pastilles o c\u00e0psules de diferent forma i color. Produeix sensacions d\u2019alerta, confian\u00e7a i augmenta els nivells d\u2019energia i d\u2019autoestima. Fa desapar\u00e8ixer la sensaci\u00f3 de gana i de son.
Una de les amfetamines m\u00e9s freq\u00fcent al m\u00f3n de les drogues il\u00b7l\u00edcites \u00e9s el sulfat d\u2019amfetamina, conegut com a speed.<\/p>\n\n\n\n
L\u2019amfetamina s\u2019uneix als transportadors de dopamina i noradrenalina actuant com un pseudosubstrat i com un inhibidor competitiu del neurotransmissor. \u00c9s a dir, l\u2019amfetamina s\u2019uneix al mateix lloc que el neurotransmissor, dopamina o noradrealina, competint amb ell i evitant que entri a la terminal sin\u00e0ptica. Aix\u00f2 fa que amfetamina entri a l\u2019interior de la neurona i desplaci el neurotransmissor de les ves\u00edcules sin\u00e0ptiques provocant la seva sortida al citoplasma.<\/p>\n\n\n\n
Si s\u2019administren dosis altes d\u2019amfetamines, com en els casos d\u2019ab\u00fas d\u2019amfetamines, la dopamina s\u2019acaba acumulant en quantitats massives al terminal presin\u00e0ptic. Si aconseguix una concentraci\u00f3 cr\u00edtica, la dopamina ser\u00e0 expulsada a la sinapsi r\u00e0pidament i provocar\u00e0 l\u2019efecte euforitzant que produeix el consum il\u00b7l\u00edcit d\u2019amfetamines.
El seu consum habitual es produeix en forma de pastilles o comprimits, i sovint s\u00f3n una de les subst\u00e0ncies amb qu\u00e8 es tallen (barregen) les drogues de s\u00edntesi.
L\u2019speed es presenta generalment en forma de pols i es consumeix per inhalaci\u00f3 com la coca\u00efna, amb qu\u00e8 comparteix els riscos associats a aquesta via d\u2019administraci\u00f3 (danys sobre la mucosa nasal).<\/p>\n\n\n\n
Els efectes provocats pel consum d\u2019amfetamines recorden en gran mesura els produ\u00efts per la coca\u00efna.<\/p>\n\n\n\n
