crap man!
Extracting DMT is easy enough for a todler to pull off...
Start with the right stuff... MHRB (mimosa hostilis root bark)
Been getting good quality form KT botnicals, with yields between 1 and 2%, sometimes over, depending if you go for all the jungle spice in there., but at least 1%, I would say is the norm.
This means 1 gram (or 1000mg) DMT from 100g of root bark (what is that 4 ounces? ). good dosages are in the 25 to 50mg range, depending what you want the day, so thats alot of mileage for your money.
Here is a tek I posted a few months ago.

Please ignore the stuff about toads in there... if you want buffo rather extract from cebil seeds...some people just never know when to stop.
In my opinion, if you never do any other drug in your whole life, you should still do DMT. It is most awesome... adn I bet heatlhy, and gives positive results and vibe.
My experiences with DMT are that people trip a little longer the first time (lucky bastards) 10 to 15 minutes
after that a good average is 5 minutes (which has nothing to do with how long 5 minutes feels on the normal daily plane we live in)
and shortest I've seen was about 2 minutes....
P.S. there is very little to prepare you for what you will see, even if you don't break past the ceiling into true hyperspace... (Oh how can you tell? at the first level, its more like someone plugged an LCD monitor's cable into your visual cortex, you may be observing pretty patterns similar to the milkdrop visualisations on winamp, but when you go past this, you are no longer just watching a "screen" you actualy end up somewhere else. You may still be aware of your normal self in the room, but you should be cool with it, don't worry abou the breathing thing, your body knows how to breath, even if it feels like its been 20 minutes since your last breath, its not real, noone ever died from smokeing DMT.
