Well-known pothead and recording artist Wiz Khalifa and fiancé Amber Rose are expecting. Which of course means they're now officially allowed to have all kinds of opinions about parenting.

But the burning – yeah, we went there – question is "what about that whole marijuana thing?"

The parents-to-be sat down for an interview with E! News to chat about their baby preparations. They were asked if raising a child might change their lifestyle a bit, especially the chronic habits of the Wiz, he responded, “Not as far as that goes.”

Rose agreed, saying, “Our son is just going to know that daddy likes to smoke.”

They believe it’s okay for a kid to know that marijuana exists and that it’s something the little one can do as an adult -- but not before. Because no one ever gets to know Mary Jane until their 18th birthday. Ever.

And Wiz and Amber didn’t make any mention of teaching the child which of the few states have legalized pot, so the kid may have to figure that out on his own after a body cavity search or two.

But Khalifa was blunt (we went there again, SHUT UP) about the fact that he'd be careful around the child: “I’m not going to be smoking right there over the baby, because smoke in general and being high is not good for a kid.”

In other words, shotgunning won't happen until at least the child's fifth birthday. Only an irresponsible parent would say otherwise.
