Shamanic Hippie was the first one I heard of to consume massive quantities and then just disappear.

His thread was the Green Dragon Project:

I have been wanting to make green dragon for a long time and today I finally threw down the money and did it. I had read a lot of recipes and many of them quoted different amounts of weed per unit of alcohol and many of them also disagreed on the best way of preparation. I decided to use 1 ounce of bud in one 200ml bottle of everclear. most recipes call for a half ounce, but I wanted to make sure I was getting some strong stuff. I first ground up the pot and then put in a cup which was itself in a pan of boiling water to heat the weed (but not burn it) so as to convert much of the THCA to THC which dissolves better in alcohol and gets you more fucked up. I then poured out some of the everclear to make room for the pot. I poured the pot in and started shaking. I am planning on putting it in hot water in the sink and shaking it daily to help speed up the maturation. I am hoping that it will be ready to strain and consume on labor day.

After posting this, he never posted back! People kept asking him what happend, but there was only silence. After awhile people starting speculating what might have happend. Did he freak Out? Go crazy? Get arrested? Did he die?

Here's what I said:

Maybe if he drank it on Labor Day, he'll wake up some time around Memorial Day next year:

Shamanic Hippie: "Oh wow, manā?¦I'm so hungry!"
Roommate: "Yo! Shamanic Hippie! Are you awake, dude? We thought you were dead there on the couch all this time. "
Shamanic Hippie: "Yeah... I drank this shit I made, and I was so high... How long was I knocked out anyway?"
Roommate: "Like nine months, dude!"
Shamanic Hippie: "Shit... I guess I'm gonna be late for work!"
