不法行為。,21,安非他命,(一)歷史：1887年合成，1931年上市(噴鼻劑，主治鼻塞)，1935年出現錠劑(主治嗜睡)，1935至1946年認為安非他命有39種合法醫療用途，1960年末濫用大盛,1970年後因管制而減少。民國78年日本嚴格取締後台灣開始氾濫，79年10月列為麻醉藥品管制。(二)使用途徑：蒸發吸入、與煙草混合抽吸、口服、鼻吸或注射。(三)作用機轉：增加多巴安、新腎上腺素釋放,並抑制回收。,22,安非他命,(四)藥理作用：自覺疲勞消失,注意力、知覺變得敏銳,興奮、欣快感，心跳加速、瞳孔放大、食慾及睡眠下降、血壓上升。(五)中毒過量：多疑敏感、焦慮易怒、躁動不安、妄想、幻覺、血壓上升、心跳加快、瞳孔放大、高燒、心律不整、出血性中風、癲癇、心臟循環衰竭死亡。(六)戒斷症狀：心情低落易怒、疲倦、焦慮、睡眠障礙(嗜睡)、食慾增加、激躁或遲緩。最嚴重的症狀是憂鬱(甚至有自殺意念或行為)。(七)安非他命精神病：表現似妄想型精神分裂症。,23,Methamphetamine,Methamphetamineisanaddictivestimulantdrugthatstronglyactivatescertainsystemsinthebrain.Methamphetamineiscloselyrelatedchemicallytoamphetamine,butthecentralnervoussystemeffectsofmethamphetaminearegreater.Bothdrugshavesomemedicaluses,primarilyinthetreatmentofobesity,buttheirtherapeuticuseislimited.,24,Methamphetamine,Methamphetamineismadeinillegallaboratoriesandhasahighpotentialforabuseanddependence.Streetmethamphetamineisreferredtobymanynames,suchasspeed,meth,andchalk.Methamphetaminehydrochloride,clearchunkycrystalsresemblingice,whichcanbeinhaledbysmoking,isreferredtoasice,crystal,andglass.,25,HealthHazards,Methamphetaminereleaseshighlevelsoftheneurotransmitterdopamine,whichstimulatesbraincells,enhancingmoodandbodymovement.Italsoappearstohaveaneurotoxiceffect,damagingbraincellsthatcontaindopamineandserotonin,anotherneurotransmitter.Overtime,methamphetamineappearstocausereducedlevelsofdopamine,whichcanresultinsymptomslikethoseofParkinsonsdisease,aseveremovementdisorder.,26,HealthHazards,Methamphetamineistakenorallyorintranasally(snortingthepowder),byintravenousinjection,andbysmoking.Immediatelyaftersmokingorintravenousinjection,themethamphetamineuserexperiencesanintensesensation,calledarushorflash,thatlastsonlyafewminutesandisdescribedasextremelypleasurable.Oralorintranasaluseproduceseuphoria-ahigh,butnotarush.Usersmaybecomeaddictedquickly,anduseitwithincreasingfrequencyandinincreasingdoses.,27,methamphetamine,Animalresearchgoingbackmorethan20yearsshowsthathighdosesofmethamphetaminedamageneuroncell-endings.Dopamine-andserotonin-containingneuronsdonotdieaftermethamphetamineuse,buttheirnerveendings(terminals)arecutbackandre-growthappearstobelimited.Thecentralnervoussystem(CNS)actionsthatresultfromtakingevensmallamountsofmethamphetamineincludeincreasedwakefulness,increasedphysicalactivity,decreasedappetite,increasedrespiration,hyperthermia,andeuphoria.OtherCNSeffectsincludeirritability,insomnia,confusion,tremors,convulsions,anxiety,paranoia,andaggressiveness.Hyperthermiaandconvulsionscanresultindeath.,28,Methamphetamine,Methamphetaminecausesincreasedheartrateandbloodpressureandcancauseirreversibledamagetobloodvesselsinthebrain,producingstrokes.Othereffectsofmethamphetamineincluderespiratoryproblems,irregularheartbeat,andextremeanorexia.Itsusecanresultincardiovascularcollapseanddeath.AstudyinSeattleconfirmedthatmethamphetamineusewaswidespreadamongthecityshomosexualandbisexualpopulations.Ofthesegroups,membersusingmethamphetaminereportedtheypracticesexualandneedle-usebehaviorsthatplacethematriskofcontractingandtransmittingHIVandAIDS.,29,Methamphetamine,SlangorStreetNames:Speed,Ice,Chalk,Meth,Crystal,Crank,Fire,GlassMethamphetamineisatoxic,addictivestimulantthataffectsmanyareasofthecentralnervoussystem.Thedrugisoftenmadeinclandestinelaboratoriesfromrelativelyinexpensiveover-the-counteringredients.Itisbeingusedbydiversegroups,includingyoungadultswhoattendraves,inmanyregionsofthecountry.Availableinmanyforms,methamphetaminecanbesmoked,snorted,injected,ororallyingested.,30,Methamphetamine,Methamphetamineisawhite,odorless,bitter-tastingcrystallinepowderthateasilydissolvesinbeverages.Methamphetamineisnotsoldinthesamewayasmanyotherillicitdrugs;itistypicallysoldthroughnetworks,notonthestreet.Methamphetamineuseisassociatedwithserioushealthconsequences,includingmemoryloss,aggression,violence,psychoticbehavior,andpotentialcardiacandneurologicaldamage.,31,Methamphetamine,Methamphetamineabuserstypicallydisplaysignsofagitation,excitedspeech,decreasedappetite,andincreasedphysicalactivitylevels.Methamphetamineisneurotoxic.Methamphetamineabusersmayhavesignificantreductionsindopaminetransporters.Methamphetamineusecancontributetohigherratesoftransmissionofinfectiousdiseases,especiallyhepatitisandHIV/AIDS.,32,古柯鹼,(一)歷史：第六世紀時,南美印地安人以咀嚼古柯葉提神。十五世紀傳入歐洲,但未流行。1860年Niemann純化出古柯因(Cocaine)並廣被當做局部麻醉劑使用。十九世紀末時,被注意到有成癮性,1930年代因安非他命合法、便宜、容易取得且效用相似而銷聲匿跡。在美國,1970年代安非他命被禁止後,再度流行,1980年代中期古柯鹼(Cocainefreebase)大量生產,價錢便宜而氾濫成災。在台灣也有人引入國內。,33,古柯鹼,(二)使用途徑：蒸發吸入、鼻吸或靜脈注射。(三)作用機轉：抑制多巴安、新腎上腺素回收。(四)藥理作用、中毒症狀、戒斷症狀：似安非他命,但更嚴重,更容易上癮。,34,CrackandCocaine,Cocaineisapowerfullyaddictivedrugofabuse.Oncehavingtriedcocaine,anindividualcannotpredictorcontroltheextenttowhichheorshewillcontinuetousethedrug.Themajorroutesofadministrationofcocainearesniffingorsnorting,injecting,andsmoking(includingfree-baseandcrackcocaine).Snortingistheprocessofinhalingcocainepowderthroughthenosewhereitisabsorbedintothebloodstreamthroughthenasaltissues.Injectingistheactofusinganeedletoreleasethedrugdirectlyintothebloodstream.Smokinginvolvesinhalingcocainevapor
