Jehovah's Witnesses, the New System, and marijuana plants....?

A JW lady came to my door the other day and started talking about the new system and paradise and I immediately pictured myself frolicking among myriads and myriads or huge marijuana plants the size of great oaks and buds like sugar coated pine cones. Now granted I had just smoked a blunt and three bong loads before I answered the door, but would you say what I imagined is realistic? When the world is returned to a state of perfection, will all that commercial seed-filled brick weed be destroyed at armageddon and then only the virtuous dank nuggets will survive?
