This is known as the "Tu Quoque" Fallacy. Bad behavior from one person does not excuse or justify bad behavior for another. The fact that drunks do it too doesn't make it right. The question is, are these children of stoners victims? Yes. Yes they are victims. So are we taxpayers.
Are you ready to re-instate Prohibition because of those drunks?
And this is the fallacy known as "False Dilema." You present only two answers as if they are the only possible answers. I wouldn't mind heavier regulation of drunks, but we don't have to prohibit alcohol.
It appears to be a regular thing among segments of humanity to blame objects instead of people for bad behavior.

If a guy fails to do his duty by his children, don't blame him, blame the booze he was drinking or the pot he was smoking.
So by your thinking, if we give you heroin, you ought to still be able to get up and work a regular job and feed your children, right? Heroin wouldn't interfere with your functionality at all because it's just a substance, and we can't be blaming substances right?
No, in this case the substance is a deadly mind altering poison, and it WILL cause you to behave differently. It will in fact be responsible for the changes to someone's life after they start consuming it.
Tampering with brain chemistry is on a level a great deal above just owning a gun.
