I might as well put this in here as well.
I've heard, dunno where, that the following procedure works pretty well in the hypothetical situation that one wishes to create a crude bufotenine extract but for whatever reason cannot follow the procedure related by 69ron. It's very quick (~4-5 hours from start to finish), but the result would probably be considerably cruder than the method proposed by 69ron.
Materials:
VM&P Naptha
Acetone
500 mL bottle
Shallow glass bowl/pan
Anadenanthera colubrina seeds
Lime OR sodium carbonate
1) Microwave 20g of seeds until the popping dies down.
2) Grind to a fine, flour like consistency.
3) Put in 500mL bottle along with 400mL of VM&P naptha.
4) Close bottle and shake thoroughly (for say, 5 minutes) and let settle.
5) Decant and discard Naptha, retaining seeds.
6) Repeat steps 3-5 once more with fresh naptha.
7) Dry seeds fully, then mix with 50% by volume of either lime or sodium carbonate and sufficient water to make a slurry.
8) Redry seed/base mixture (20 second pulses in the microwave would theoretically work).
9) Regrind to flour like consistency.
10) Put in 500 mL bottle along with 400 mL of acetone.
11) Close bottle and shake thoroughly. Let settle.
12) Decant acetone to evapping dish, being careful not to spill over any seed material and evaporate to dryness.
13) Repeat steps 10-12 once more.
14) Scrape up dry impure bufotenine.
The rumor is that 25-30 mg is a very strong dose.
