Robert Altman has yet to devote one of his well-populated and naturalistic observational studies to the milieu of potheads, perhaps because the world is not yet ready for three hours of Shelley Duval and Lily Tomlin snacking on Doritos and giggling on a couch. (We'd disagree.) However, should the octogenarian auteur choose to go there, the NY Daily News reports that he'll have already done all his required research:

His heart transplant didn't make "A Prairie Home Companion" director Robert Altman cut back on his marijuana intake - if anything, he's enjoying the ganja even more now.

"I've increased it because of my heart condition. I even have a prescription for marijuana pills," he told us when we asked him about his fondness for the illicit drug. [...]

Altman loved working with young Lindsay Lohan on his new flick, but he didn't mention whether he and the wild young lass partook of any illegal substances on the movie set.

While we know the actress has been bong-adjacent on at least one occasion, and that the two seemed to have a relaxed chemistry, it would be purely presumptuous to conclude Lohan's mentor was smoking her on some sweet, B.C. wheelchair weed in his trailer before every shot.
