sanyukt raajya America mein, Chicago traanjit praadhikran ne poori pranaali mein 2002 ke baad se rel bhugataanon ke liye Chicago card aur Chicago card plas ki peshakash ki aur 2005 ke baad se bas bhugataanon ke liye. MBTA ne RFID saksham chaarleekaard ko 2006 mein Boston ke sampoorn metro, streetakaar aur bas pranaali mein laagoo kiya aur dashakon puraane tokan aadhaarit kiraaya sangrah pranaali ko pratisthaapit kiya.
jab tambaakoo ka sevan kiya jaata hai, jyaadaatar nikoteen jhulas jaata hai. haalaanki, ek khuraak halki shaareerik nirbharata ke liye paryaapt hai aur ek majaboot manovaigyaanik nirbharata ko halka karne ke liye paryaapt rahati hai. vahaan tambaakoo ke dhuen mein maujood acetaldehyde se haaramon(ek MAO avarodhak) ka gathan bhi hota hai. aisa lagta hai ki nikoteen ke nashe mein ek mahatvapoorn bhoomika nibha raha hai- nikoteen ki uttejanaaon ke javaab ke roop mein ek javaabi kaarravaai ke taur par naabhik accumbens mein ek dopamine ki suvidha jaari ki gayi.[51] adhyayan ke liye choohe ka upayog karke yeh doharaaya gaya ki nikoteen ke upayog ke baad kam jimmedaar naabhik accumbens koshikaaen sudrudheekaran ke liye jimmedaar hain, jo aparaadh mein fansaane ki kai ghatnaaon, jismein keval nikoteen hi naheen isi tarah ki cheejein majabooti ko kam kar deti hain.[52]
yadi kisi taig yukt vastu ka bhugataan kredit card ya ek lauyalti card ke upayog ke saath sanyojan ke roop mein kiya jaata hai, to paroksh roop se us vastu ki duniya bhar mein adviteeya ID (RFID taig mein samaahit) ko padh kar kreta ki pehchaan ko nikaalna sambhav ho jaaega. aisa tabhi sambhav hai jab dekhne vaale vyakti ke paas agar lauyalti card deta aur kredit card data tak abhigm bhi ho aur upakaran wala vyakti yeh jaanta ho ki aap kahaan jaane vaale hain.

tambaakoo mein sakriya tatv, vishesh roop se cigarette mein patton ko jalaakar aur vaashpeekrut gas ko saans se kheenchakar praapt kiya jaata hai. yeh jald aur prabhaavi dhang se padaarthon ko khoon mein avashoshit kar fefadon mein koshikaaon ke jariye pahunchaaya jaata hai. fefadon mein lagbhag 300 million rakt koshikaaen hoti hai, jiske satah ka kshetrafal 70 m2 (ek tennis court ke aakaar ke baraabar) hota hai. yeh vidhi vifal hai kyonki poora dhuaan saans se naheen kheencha jaata hai aur sakriya padaarthon mein se kuchh maatra jalaaye jaane ki prakriya ke dauraan vaashpeekaran mein nasht ho jaati hai.[9] pipe aur sigaar ka dhuaan uchch kshaarayukt hone ke kaaran saans se naheen kheencha jaata jo shvaasanali aur fefadon ko haani pahuncha sakte hain. tathaapi, cigarette (pH 5.3) ke dhuen ki tulana mein iske uchch kshaarayukt (pH 8.5) hone ke kaaran sangathit nikoteen aur adhik aasaani se munh mein shleshm jhilli ke maadhyam se avashoshit kar leta hai.[45] sigaar aur pipe se nikoteen avashoshan baharahaal cigarette ke dhuen se bahut kam hota hai.[46]


prativedan ke liye engineer digital system ke prakaaron par vichaar karte hain. adhikaansh digital system "sanyojan system" aur "anukramik system" mein vibhaajit ho jaate hain. sanyojan pranaali mein hamesha jo input diya jaata hai vahi aautaput vah deta hai. yeh mool roop se laujik prakriya ke set ka pratinidhitv karta hai aur jiski charcha pehle hi ki ja chuki hai.
