Elevation Ministries -- a Colorado-based religious org -- announced the launch of the International Church of Cannabis, which will be a "spiritual home to adults who seek to become the best version of themselves" ... with bud.

Congregation members call themselves Elevationists, and their mission statement sounds right on point: deepening and accelerating one's spiritual journey of self-discovery. Again, with bud.

One more nug ... the chapel is 113 years old and was recently renovated with paintwork from Kenny Scharf -- who's featured at the Guggenheim. So, it's a classy joint, if you will.

2 Chainz is going to be in town that weekend, and we're told the church is hoping he comes to worship. Chances are high, we're thinking.

Let the choir sing ... Puff, puff, pass. Amen.
