Ideas, inventions that may never come to market

My friend has a marijuana-scented one. This way when a cop smells weed in his car, he just blames it on the air freshener.

Does it really smell like pot? If so, where did he get it?

I haven’t talked to him in a while, but I know it’s also shaped like a marijuana leaf. It certainly resembled the scent, although I’m not a connoiseur.
