This is what Wikipedia says about cocaine in Coca Cola:
Pemberton called for five ounces of coca leaf per gallon of syrup, a significant dose; in 1891, Candler claimed his formula (altered extensively from Pemberton's original) contained only a tenth of this amount. Coca-Cola once contained an estimated nine milligrams of cocaine per glass. In 1903, it was removed. After 1904, instead of using fresh leaves, Coca-Cola started using "spent" leaves – the leftovers of the cocaine-extraction process with trace levels of cocaine. Coca-Cola now uses a cocaine-free coca leaf extract prepared at a Stepan Company plant in Maywood, New Jersey.
So, it's been a long time since there was cocaine in Coca Cola.
May you live as long as you wish and love as long as you live.
