Hi! Here some dosages for smoking JWH-018:
Light 1 - 2 mg
Middle 2 - 3 mg
Strong 3-4 mg
Havy 4+ mg
As for ADB-Pinaca, the exact dosages for it have not yet come across to me. However, given its potency, I would recommend making them lower than for JWH-018.
I cannot but note that intoxication with these substances carries risks of psychotic reactions and fatal complications. Be careful, take care of yourself.
