Robin Thicke confessed to burning $500,000 on pot

There’s little doubt about the state Robin Thicke was in when he co-wrote Blurred Lines.

“Weed is my crutch, my muse, the lesser of all evil,” Robin told Britain’s The Sun.

The singer added he has spent more than $500,000 on marijuana — even though he has a friend who cuts him a good deal.

“My buddy runs a store, I can get medical marijuana. When I’m at home, I’m a non-stop chimney.”

Robin said he tried to quit smoking at one point, but realized it was futile… Although we’re pretty sure a quick trip to the Barbara Evans’ Rehabilitation Facility would set him straight.

I can just picture it now: “Robin, I heard ya singing about blurred lines and I know what ya meant. Now ya spent how much on the weed? Did ya pay the rent?!”

Robin’s penchant for pot became public in February 2012 when he was arrested for possession in Manhattan.
