Can we wait for e-cigarette trials? | Chemistry World
"It also takes four years to get the results from cancer studies and they notoriously err on the side of safety. For example, of more than 30 ingredients of coffee tested for carcinogenicity in rodents, more than 70% had a positive result. Does this mean we are regularly enjoying a brew of carcinogens? No – there is no such evidence. Some studies even show that coffee may reduce cancer risk.
In the short term, self-restricting the use of additives and using fast cell- and computer-based evaluations of safety will help clarify the safety of e-cigarettes. And in the medium term, controlled trials will be necessary. But if we wait for this evidence to emerge and prohibit or hinder the use of e-cigarettes, we would probably miss a tremendous opportunity to save lives on a large scale."
