To TIlE EDIToR:Regarding the article, “¿�WhyWe

Smoke,―by Frank P. Foster, M.D., inCa—A Cancer Journal for Clinicians,Vol. 17, No. 3, page 118, I do not findthe tobacco farmer-manufacturer-advertiser-distributor-dealer to be themajor villains. These capitalists aresimply obeying the animal law thatwhatever is desired will be acquired ifvalue exchange is feasible. Nor shouldwe take these people to task for recognizing that publicity begets profit. Theproblem is that the young are nottaught early enough that cigarettes areas unnecessary as they are undesirable.Or, more explicitly, cigarettes are awaste of time and money as well as a

health and fiie hazard.If you must find a villain, look to

tobacco's silent partner: government.Public enterprise takes the lion's shareof the loot in federal and local taxesand takes it on a number-of-cigarettesbasis which encourages the lengthening of the cigarettes and an increase ofthe dose per pack of lung contaminants.The tax could just as well be on amilligrams-of-tar-per-pack basis whichmight inspire the capitalists to cleanup the product.
