Cosby challenge

A two person drinking game that is played as follows:

Supplies needed:

-A 30 rack of beer or a bottle of alcohol with a mixer
-Two pills containing 100mg* of MDMA each (You can play this with any powdered substance really).

-Cups.

Instructions: You and the other player drink together like you normally would. The objective of the game is to get the MDMA into the other players drink without them noticing. Whichever player’s pupils dilate first loses but also wins (because MDMA).

Note: Named after famous MDMA chemist Mike Cosby.

*100 US mg converts to around 350 British mg.

Friend: Alright, Cosby challenge starts in 3... 2... 1... GO!

Me: *sets down drink*
“I’m going to the bathroom I’ll be right back.”
