Sure why not? (Sarcasm.) Add to that, no treatment for anyone who drinks or smokes, no treatment for overdoses (self inflictted), anorexia or bulimia other than counselling, no treatment for injuries sustained in dangerous pursuits such as rugby, football etc since it was a choice, no treatment for pregnant women as that was also a choice, no treatment for erectile dysfunction as sex is not essential. And especially no treatment for anyone who injures themself out drunk on an evening spree. Might as well kill all the oldies too by this point, as lack of mobile joints means they will get fat.
