I know that this subject might have been discussed numerous times
but it is really urgent...
I am interested which is best method of extracting most of the canabinoids from cannabis?!
I have DCM,chloroform,IPA,MeOH,EtOH,acetone and toluene available as solvents.
Butane is ha(za)rd to work with and I lack proper apparatus,DCM and acetone seems to be prime candidate.

Since some of you might know that THC is not only important ingredient in cannabis,it is desirable
to chose solvent that will extract all of these but not to extract wax nad other crap.
I know it can be and has been done sucesefully by using some of these solvents many times
but I started this tread so you can share your best experince,methods...
Cannabis is rather expensive here now,illegal and has low % of active ingredients.

Elderly relative with diabetes,removed pancreas and multiple liver problems (including cancer)
came to phase when extreme nausea and almost total lack of appetite became serious problem.
Patient is refusing most of conventional treatments due the extreme phobia of
hospitals and severe depression.
I know that some weed might help significantly for nausea and appetite,
if nothing else than for improving life quality.
Patient is more than 80yr old,newer smoked,previously good health
and won't even consider taking cannabis voluntarily,so adding few drops of
cannabis extract in tea or milk is desireable method.

Thanks in advance!

Will that person consider the use of various JWH or WIN compounds? Some of these in studies have been showed to induce tumor regression, blood sugar modulation, pain relief and appetite stimulation.

Still out of all the solvents you listed I would go with the most polar yet volitile of all being either DCM or Chloroform. You will get alot of other things comming along for the ride using and alcohol or acetone as the solvent. Butane extraction is fast and simple to accomplish so personally I would use that but if you fear it then use DCM instead.

acetone does a nice not perfect job of cleanly extracting cannabis.
you can then esterify it in whatever solvent you extracted it into and remove the acid anhydride by stirring with methanol to make the methyl ester which is much more volitile and evaporates easily.

were talking about pure processes ethanol drags tars and oils with it.
acetone is nice i'[ve tried it myself and when you add propionic anhydride the thc molecule just sings when it hits your brain.

well the propionyl ester is mighty fine better than the acetyl ester it is pure euphoria zero anxiety best i could describe it .
the euphoria was a bit embarassing like meglomania beyond normal euphoria perhaps not good.
acetone will drag some tars but not many i've done it esterified it in acetone and was fucking pleased to the hilt how can i say more?
one hit and quit on all my test subjects after one hit they had to hit the fast food restaraunts they forgot about the dope what more do you want?

mum is always a bipolar bitch like i am she's more afraid of me though i tend to be violent.
you know society puts that violent sticker on you and where can you work? ahh but i found me niche,undertaker i can con grieving familes out of thier savings with a smile on my face and, i'm not dealing with "people" just carcasses.
they don't give me any bother and i'm not scared of death.
it suits me fine. i could care less
on to your question it makes it more lipophilic, if you know anything about drug chemistry lipophilicity means it crosses the blood brain barrier more effieciently.

swim has 2 pdf's that may be very useful viv-a-vis your inquiry.

1.Cannabis Alchemy by D.Gold
2.Marijuana Chemistry, Genetics, Processing, & Potency by Michael Starks (2nd ed)

should be readily available online if swiyou looks hard enough, many solvents and extraction methods are discussed...
Grasscity may be a good forum to search in as well, though terribly unscientific

edit: found attach option 

Will stick with pentane,hexane,DCM and chloroform and inform you how it went...

The optimal arrangement of glassware for the extraction of cannaboids involves the use of a percolator    Since the cannaboids are terpenes, hydrocarbon solvents are preferable as opposed to ketones, alcohols or chlorinated hydrocarbons 

As was posted in:

https://the-collective.ws/forum/index.php?topic=21193.0

a hole can be drilled in the  bottom of a glass bottle to create a small percolator    It's also possible to create a usable percolator from sheet metal, perhaps an old Hive post concerning that can bee located
