Cannabis tincture....decarb necessary?

Alright so at the point of harvest, THC is mostly in the form THCa which is non-psychoactive. Simply put, over time during the curing process, THCa will become THC. But this takes a VERY long time, so to speed up the process, you'll need to decarb. The average weed you'll get on the streets probably contains around 15% THCa and 3% THC at the point of purchase, after a proper decarb you'll probably get it to be around 16% THC and hardly any THCa. To decarb, I recommend a temperature of around 230F for 45 min. This is based on studies done by SC labs and by the fact that caryophyllene is degraded at temperatures above 246F. No other important component of cannabis begins degrading below 270F so you really won't have to worry about anything else. I would completely disregard any answers that tell you to use a temperature below 200 or above 250 because they are basically pulling those temps out of their asses without any scientific backing

I am certainly new to all this. I recently tried my hand at making an oil for my vape. I made a tincture with 3.5 g mj and everclear. I did not decarboxylate due to mixed instructions. Some said that the vape process will take care of the process of decarb. I have two questions. Do I need to decarb before making a vape oil?

I followed the QWISO method on this post:

If so, is there any way to recover? I now have about 5 mL of oil, but have not tried it yet.

Thank you
