You can, I have done in the past, but you're talking 60 individual gram bombs of dry cactus. That's not going to do your digestion a lot of good, and you know what this stuff is like in your stomach anyway, right? You'll have to drink a lot of water once it's down you or it'll dehydrate your insides.
You could try the green slime with a soft straw? I never found a satisfactory solution, good luck.
Essentially you want to look into alkaloid extraction techniques. There are a bunch of ways to do this, ranging from the scientifically approved (acid/base extraction with all the correct glassware and chemicals) through to boiling a big pan of ethanol on your hob and hoping like hell it doesn't catch fire and blow your house up.
Generally what works for me is: cook up your powdered cactus in a big stainless steal pan in a fair amount of water with some lemon juice in it (yeah ethanol is best, no you don't want to be boiling ethanol near naked flames. Really). Once it's been simmering for an hour or so, filter the liquid through an old tea towel or something and repeat the process once or twice more with fresh water/lemon, to make sure you get as much of alkaloid content out as possible.. Put all three lots of cactus water back in the (washed) pan and simmer it until it's reduced. You can reduce the product all the way down to a residue which you can scrape up and eat or at least get it down to a manageable amount of liquid.
The dry product of this type of bush-league extraction is (was?) colloquially known as "dirty sanchez" and rudimentary compressed pellets of this residue is how mescaline was commonly distributed when it was a more common drug (60s, early 70s.)
Good luck, and I hope this post wasn't too rambling.
>>6829 That was the minimum with the powder I had. Did you not manage to get the slime down you? How much did you use then? Erowid should have better weight guides than my ailing memory, check there.
>>6827 Ethanol is fine if you use an electric heating element.
If you want higher purity then start by simmering in water with vinegar or lemon juice for a while before filtering off the cactus junk and adding baking soda to the solution. Then by adding ethanol (or any other organic solvent such as ether or acetone) and mixing vigourously (off the heat) the now basic alkaloids will pass into the ethanol and dissolve. The tricky part is now to get rid of the bottom water part - ideally you'd use a seperating funnel for this but any glass container with a nozzle at the bottom will do. The dissolved alkaloid crystals should then precipitate on slow cooling - if not then boiling off the solvent would be your other option. Assuming they do precipitate you can just filter the crystals off and there you have it. Little bit more involved but you should actually get a reasonably pure product.
No. Not yet, I've a bit of a flu on right now so I'll try it when I'm feeling better. Watch this space. In a few days you'll likely see loads of pictures of budgies or skeletons or something popping up in this thread.
>>6831 Christ I really shouldn't try and talk chemistry whilst drunk. Obviously don't use ethanol because it's miscible with water, dichloromethane would be ideal but anything else that is immiscible with water and has the right solubility profile (i.e dissolves the alkaloid at high temperature and doesn't at low) will do. Also you're probably better off just evaporating the solvent off rather than filtering if the crystals are very small.
