How do you use full spectrum cannabis oil? - eviltoast

I got a medical card here in LA and the prices are outrageous. Getting a dablicator with full spectrum oil seems to be the most cost effective. Trouble is I can’t seem to figure out how to use it.

At first I just ate it but I think I wasted $90 because I felt nothing and I don’t think it was decarbed.

Next I got some refillable 510 thread vapes and a small syringe to fill it. That has been a pain but it at least works a bit.

How am I supposed to use this stuff? Is it all the same or are there different kinds? Is it decarbed at all or not meant for vaping?
