Method Man - 'How High' Sequel

The high-ly anticipated sequel for the cult classic "How High" is stuck in development hell ... Method Man tells TMZ ... but it's not up in smoke just yet.

The rapper and weed rights advocate was out in L.A. yesterday when we asked about the status of the franchise ... and Method cringed in frustration.

Method says the script is still in the works ... but if the public wants to see it made, they need to start voicing their support in a big way ... NOW.

As for the kind of support he wants ... it sounds like a remake of "Veronica Mars."
