I've been making rosin in coconut oil suspension for a little over a year now. Some thoughts about consumption;
First, it only takes a little oil to 'dissolve' (more like suspend) the rosin enough to dispense with a dropper. If you press at low temps, the rosin will not be decarboxylated, so you can dose higher without getting ripped. A fair number of folks prefer it this way. One friend reported that his drops got more potent over time. He thought it was because of body heat from carrying the bottle around in his shirt pocket. Others (I didn't try it yet) said that a few drops baked on a cookie kicked the meds up into 'recreational' territory.
In any case, you can just dose the non decarbed rosin/oil higher and you will get recreational level buzz. It is possibly a bit different feeling though. More stimulating, and 'up' is what everyone says. Maybe the THC is a bit downplayed, while the terpenes are not?
Green (chlorophyll) might not taste great when dabbing rosin, but it's very desirable if you plan to eat it. Phytol (and other phytochemicals) are known to promote good flora and fauna in the lower intestines, so don't go crazy trying to make your rosin look like shatter if you plan to take it internally. One of the first things you'll notice when swallowing rosin-oil-suspension is that it calms your tummy, immediately.
After making a few batches of way-too-strong drops, we settled on the amount of 1-2 grams (strain dependent) of rosin in a 15ml bottle of coconut oil. That seems to be the amount that the medical folks can do 2-5 drops and the rec folks can just eat a whole dropper full, and everyone is as happy as they want to be!
Oh, almost forgot about the accidental 'head dose' experiment! One day, I licked off the tool I was using to transfer globs of rosin (who hasn't done this?) and a glob stuck to the back of my upper front teeth. Tasted mighty strong for a few minutes, but after a few sips of water it calmed down and I forgot about it. About twenty minutes later I noticed that my mouth was numb. A few minutes after this my whole head felt the same way. I had just been to the dentist the day before, and the lack of pain was very noticeable. About forty minutes after eating the glob, I started to feel seriously high. Just about at the point where you start wishing you hadn't eaten that last edible, it was that strong. Then, about ten minutes later, it started to ease off. About an hour and a half after eating, the effects had all but worn off. My thoughts are that I bypassed the stomach/intestines route and received what amounted to a topical dose direct to the head. Anyone else have an experience like this? Like I said, I'm sure lots of other folks have licked rosin off a knife or transfer tool.
