Los Angeles stinks. Not just of the usual things: sex, money, suntan oil, hipster food, surfer wax — odours that I like. There’s a new whiff in town, and it’s a bad one. Weed.

The smell of marijuana hangs over LA like an invisible menace. It’s an omnipresent fug. To walk from one end of a street to the other, whether it’s along the chaotic Hollywood Boulevard or the half-gentrified, half-terrifying Broadway in downtown LA, is to risk developing a skunk habit.
