420 BLAZE IT BRO!!!

My father is on oxygen and was proscribed marijuana.

Hopefully he's not dumb enough to smoke it while breathing the oxygen!

Marijuana isn't the problem, his choice in how he's taking it is the problem. You can drink it in tea and it's waaaay less harmless for someone especially in his situation than it would be to smoke it.

Stupid man go boom!

Just be glad they asked before they lit the entire place up

A lot of cigarette smokers on oxygen because of lung disease blow or burn themselves up -- usually at home.

I'm still amazed my grandma didn't blow herself up doing that.

This is some 'Frank and Carl Gallagher' from 'Shameless' type of FML.

A vaporizer would be better than a joint -especially in his case

At least he's sharing with his son. Hahaha.

That would light up the whole joint.

THIS IS CALLED JOINT FAMILY.

Why not? Just make him do it outside where no innocents can be harmed. Let nature take its course.
