What, if any, stoner films deserve to be preserved in the collection?

I suppose one could call Withnail and I something of a stoner film, though the characters only get stoned at the end of the movie, and are primarily imbibing in alcohol for its majority.

I assume many people are going to say The Big Lebowski, but in my opinion, that movie has already been very well preserved in other ways.

What other works that are considered to be in the “stoner” genre are important enough to deserve the preservation of a Criterion treatment? My vote would be for Inherent Vice, one of the lesser appreciated Paul Thomas Anderson works.

Edit: pardon my ignorance, I clearly neglected many great stoner films already in the collection.
