The OD level for weed is second only to LSD, and that's somewhere (far) over an ounce, but I forgot the exact amount. That doesn't sound like much, but the average dose is 200 micrograms, which is .2 grams.

If I am to die, I want to die after drinking a liter of pure LSD.

Y'know, Aldous Huxley (an author, for those young'uns and/or ill-read folk) died with an IV of pure LSD draining into his arm for a couple days, and he didn't OD.

Huzzah for tangent thoughts!

Now, go back to saying what's been said 30-odd times already.
