These flaws are also noted by Dr. Robert West, director of tobacco research at University College London, who that: "the study was not able to assess whether or not for cancer patients who smoke using an e-cigarette to try and quit is beneficial "because the sample could consist of e-cigarette users who had already failed in a quit attempt, so all those who would have succeeded already would be ruled out"."
