1. Neighbors
By far the biggest box office success this year for a stoner movie, Nicholas Stoller's Neighbors has earned $150 million (18th best in 2014). Seth Rogen and Rose Byrne co-star as harried parents who have to deal with the frat house next door, led by Zac Efron and Dave Franco. Rogen makes a peace offering with pot and parties on shrooms. Ultimately, they outsmart the dimwitted frat boys, whose house is lit up with the huge marijuana leaf pictured above.
