The Appropriation of Tobacco by Europeans
Forobviousreasons,untilColumbuslandedonSanSalvadorin1492,thetobaccoplant didnotattracttheinterestofEuropeans,althoughitmaybenotedthattheAmerindians usedthewordtabagotodescribethepipeusedfortobaccosmokingratherthantheplant itself.OnhissecondvoyagetotheNewWorld,Columbuswaspresentedwithabunchof tobaccoleaves,buthadnoinklingoftheirintendeduse.In1527,theirstbishopofthenew

colony,FrayBartolomédeLasCasas,wroteadescriptionofthepropertiesofthetobacco plant[7]. Although the Amerindians presented the Spaniards with tobacco leaves as a gestureoffriendshipanddevotion,theplantlostallitsceremonialreligioussigniicance overtheensuingcenturiesinthehandsoftheSpaniardsandotherEuropeans,andtobacco becamealuxurycommoditythatwasexploitedsolelyforcommercialpurposes.
Afterhisreturnfromseavoyages,SpaniardRodrigodeJerez–creditedwithbeingthe irstEuropeantobaccosmoker–usedtowalkthestreetsofhishomeportofAyamonte, withsmokebillowingfromhismouthandnose.Believinghewasconsortingwiththe Devil,thelocalclergyhandedRodrigoovertotheInquisition,andhewasimprisonedfor 10years!ThiswasinstarkcontrasttotheextremelyliberalattitudeoftheSpanishcolonial rulersoutsideSpainasfarastobaccosmokingwasconcerned.Afterhissecondvoyageto theNewWorld,ColumbusbroughtanumberoftobaccoplantsbacktoSpainwherethey were used initially as ornamental plants in the gardens of the aristocracy. Jean Nicot (1530–1600),FrenchambassadortothePortuguesecourt,conductedanumberof“experi-ments”whichidentiiedthehealingeffectsoftobacco.In1559,onthestrengthofthis conviction,hesentsomeplantstoParisforCatherinedeMediciwhohadthemprocessed assnuffpowder,andsuccessfullyadministeredthemtoherson,CharlesIX,asaremedy forhisheadaches[8].TheSpaniardNicolasMonardes,aphysicianattheUniversityof Seville,wroteatreatisein1571onthemedicinaluseoftobacco,andhiscompendiumwas veryrapidlytranslatedintootherlanguages[9].By1590,theplantwasalreadyknownas Nicotiana,andsince1828Nicothasgivenhisnametotheprincipalalkaloid,nicotine.
TobaccoarrivedattheEnglishcourtofQueenElizabethIin1573,andby1614therewere alreadymorethan7,000tobaccoretailoutletsinLondon[10].Beneitingfromtheextensive tradingrelationshipswiththeSpaniardsandthePortuguese,thetobaccoplantwascarriedto thePhilippines,totheSoutheastandEastAsia,aswellastoAfricaand,bythebeginningof theseventeenthcentury,evenfurtheraieldtoJapan,KoreaandChina,fromwhereitalso enteredTibet,Mongolia,andSiberia[11] .Tobaccobecameanimmenselyvaluablecom-mercialcommodity,comparablewithcocaineandotherillegaldrugsatthepresenttime.
