If you're wanting to manufacture pills, you should do it the way my lady does. Quick, simple, and effective...

This kit contains everything you need and also comes with a excipient powder to help your body process more of the pill, faster, and digest it better resulting in a much better high. I've never personally assembled the pills, but my lady does and it appears to be pretty simple once you have the process down...
Also, after you purchase your refill kit and whatnot, it comes down to 20 something cents per pill, plus the cost of your trim/bud/etc. and in clubs these things generally go from $10 each to $15 for 3 depending on the strength.
But yes, as oregon said, be careful because you can very easily freak yourself out on cannabis if you consume too much... the pills have a much stronger effect than smoking it, and even stronger than most medicated edibles... I don't think I could ever stress how serious I am being about this... Too many pills will result in something like:

Most I have ever done was two, and it was way too much. Got the shakes, felt really cold, yet I was sweating- text was waving around my screen, I had all sorts of fucked up thoughts (dont play GoW2 by yourself after taking pills... the game just has a very morbid and upsetting feel about it LOL) -- basically, I had a full on whitey... I was never so high in my entire life.

oh, and if you decide to make a bunch of these, and take 3 or 4... dont say I didn't warn you... as silly as it sounds, these pills are the serious business.
oh yeah, and when you burp after eating these (you may burp quite a bit), its going to smell/taste like hella weed, so be careful if being inconspicuous is what you're about.
