Cycling without a helmet ======================== * Sarah Giles An advertisement for Atacand (candesartan cilexetil) that appeared in several issues of *CMAJ* in 2006 shows an older man on a bicycle without a helmet and asks, "Where will his heart take him today?" Without a helmet, his heart may help him to pedal to intracranial disaster! *CMAJ* needs to demand that advertisers set a better example. ## Footnotes * Editor's note: Any drug advertisement submitted for publication in *CMAJ*, including the ad described in this letter, must have prior approval from the Pharmaceutical Advertising Advisory Board (PAAB). Beyond that, *CMAJ* has little control over the content of PAAB-approved drug ads. We strongly support the use of bicycle helmets, and publication of this ad was not intended to indicate otherwise. We have brought this to the attention of the advertiser in question and thank Sarah Giles and other readers for bringing this to our attention.
