Weed ejuice

So ive been watching some videos on how to make it. I found some that you would use a gram of oil and add some special flavoring and vg/pg and put it in the microwave for 10 sec and you have weed juice. Would I have to decarb the weed before making oil or is just vaping it enough to activate the thc?

Yes I use my rosin chips to make my vape my first run will be done Friday. I did the VG method takes 3 months will be glad to let you know how it turns out

i've tried it a few different ways. i'm about to give up and buy some wax liquidizer, and some ej-mix, and try both to see how i like them.
shit takes forever to dissolve in VG. plain pg separates and makes a mess for me after a few days.
got some peg 400, it works better, but if i make it strong enough to feel an effect it clogs up my coil.
apparently, both the WL and the EJ use a mix of peg 200, 300 and 400, to promote material to dissolve and not separate, and i don't want to be buying all that shit and experimenting myself till i get it right. at least not till i get bored and ticked about the price of WL or EJ
