Simultaneously getting faded off of

1). Cannabis flower (weed)
2). Cannabis concentrates (Wax/dabs)
3). Hashish
4). Edibles

It is best to take the edible first, wait 45 minutes, smoke a joint or blunt with both flower and hash in it, and then take a dab. If you’d like you can just take an edible and smoke a joint/blunt with all three of the remaining horsemen.

Will get you hella faded, do not drive.
Example 1).

Me: Yo what you got?

Plug: Anything

Me: Weed?

Plug: Hell yeah. The four horsemen!

2).

Friend: Dude you look fucking out of it today!

Me: Yeah, last night I took an edible, smoked a blunt with flower and hash, and took like 7 dabs. I’m pretty zonked even still today.

Friend: Ah! The Four Horsemen of the Cannapocalypse!
