Well that sounds like a big fuckin waste to me. Possible, maybe, but a big fuckin waste. Sure, you COULD spend the whole day smoking blunt after blunt till you've finished off a pound of mids, then wake up the next day poor and out of smoke. Or you could just buy a few ounces of dank and build a gravity bong. Everybody will still be blazed out of their skulls and you'll still have a shitload left when you wake up the next day. But hey, if you're not paying, take advantage I guess.
