i heard "dis-jointed"...look here:
"Cheech Marin and Tommy Chong will be doing another film together, titled Dis-Jointed, which is expected to enter production in late 2004.
In the movie, characters Pedro and Man invent a hair restoration marijuana lotion, but can't remember which pot they used to make the formula. So the stoners embark on a road trip, testing and smoking many crops of cannabis, trying to find the type they used. Meanwhile, they are chased by cops and pharmaceutical companies."
