MJ Anniversary Memorial -- Up In Smoke

Chronic Michael Jackson fans have found their own way to honor the King of Pop -- and the plan involves copious amounts of Thelonious Skunk.

While thousands of fans pay tribute at Forest Lawn in Glendale, a dude calling himself NJ Weedman is hosting a party just a few miles away  ... a party that happens to light up at 4:20 PM.

We're gonna go out on a limb here and guess the MJ estate won't be too thrilled with the party poster ... which features MJ holding a giant dooby.

Oh yeah ... and you might recognize the dude with dreds on the left from his last big pot party -- the Obama One-Year-in-Office Celebration.

It's gonna be dope.
