Roman aime Camille, autant qu'il aime ses deux filles. Mais il cache à tous un grave problème d'addiction, qui pourrait mettre en péril ce qu'il a de plus cher. L'amour a-t-il une chance quand la confiance est rompue?
Il accrédite pour le public l'idée que la cocaine est aussi "contagieuse" que les maladies infectieuses -> "Il suffit d'y toucher".
Mais cela pose le problème de la positivité à la cocaine par contact indirect.
The question posed by this research involves how frequently one can expect to contactcocaine in day-to-day living experiences where drug use may not normally be suspected.
Issues concerning contamination are germane to medico-legal investigators who evaluate the significance ofdrug test results in
(1) questioned deaths, (2) public health concerns, (3) drugs crimes, and (4) druguse toxicological tests potentially caused by external contamination, such as hair, sweat, and skinswabs.
Previous surface studies focus mainly on currency drug contamination; few have addressed other common surfaces.Public surfaces handled by a large number of people, such as building entrance door handles, bankcurrency dispensing machines, food store shopping carts, and service station fuel pumps within the New Haven, Connecticut metropolitan area were tested.
Socioeconomically, the distribution of items tested ranged from working-class to upper-middle class areas.
Results were obtained using the Securetec Drugwipe IIÒ which is an immunological, on-site test device. Precautions were takento avoid carry-over and other potential contamination from handling including single-use latex gloves which were pre-tested as a negative control immediately before swabbing.
Analysis was performed according to the manufacturer’s instructions and in the laboratory to standardize conditions.
Drugwipe IIÒlimit of detection (LOD) is50 ng.Test results revealed 78% positive for cocaine substances as follows: fuel pump buttons for creditcard authorization, 100% positive (n= 10 individual locations); ATM machines for currency with-drawal, 100% positive (n= 10 individual locations); grocery store shopping carts, 70% positive;academic building entrance doors, 30% positive (n= 10); and shopping mall entrance/exit doors,100% positive (n= 5)

Cocaine has been measured in its unchanged form in sweat at 33-3579 ng/patch/30 min from heat-induced sweating; 43-3799 ng/wipe and up to 315 ng/patch during one week after nasal doses of 50-126 mg(1). Approximately 1-9% of cocaine passes through the body unchanged, 35-54% is excreted as benzoylecgonine and 32-49% is excreted as ecgonine(2).

Ah!!! J'ai d'abord pris ta phrase au sens propre (ou figuré? ), et cru que le film laissait entendre que puisque le père était cocaïnomane, le reste de la famille allait inéluctablement le devenir...

Non mais ils sont quand même "positifs" (aux tests). Amicalement
