I find it absurd (obscene) that 18 year-olds can be sent into combat to kill women and children when "necessary." Period.  But then to turn around and say they are too immature to decide if or not to smoke seems so inconsistent as to cause people to lose respect for government. And we all know where that leads. On the other hand, to muddy the argument, if we take a reasoned stand now against teenage smoking based on immaturity, just maybe it will lead to rethinking the military thing, too.
