Well, I have eaten massive amounts of oil over the last month. I also smoke about an ounce of bud a week. The oil had very little effect on my high even though I ate about a gram or more a day for a month.
The oil was made with a butane extraction from buds - I've gone through a lot of
. I wish I had counted the jars, but I didn't.
I am still on prescribed meds for blood pressure, but since I began smoking it has been 120/80 or lower. The oil did not lower it further.
Neither did the oil lower my blood sugar but it was already pretty perfect (usually below 110 and never higher than 142). Also I take metformin for that. But the long term test the doc does (A1C) went below 7% (very good for a diabetic) when I started smoking. I have not had the A1C test done since I ate the oil - though I am overdue.
So really, it seems to me smoking an ounce a week has provided the benefits already; the oil did nothing for me.
I also am a medicated bipolar & I think the meds I take for that limit my high. Different weeds taste different, and certainly have different potency, but my high is always the same. Kinda strange.
