Hello, I'm trying to make thc liquid for e-cig but without any success. I'm using Rick Simpson oil and PG/VG 50:50 but when i try to dissolve the oil in pg/vg it sits like oil in water and no matter what i do (heat cold) it can't be dissolved. I've just tried only with PG or VG and effect is the same... Did someone have a same problem like me? I will appreciate any help. Thank you.
