Hi I have a question about tincture usually I been making coconut oil infused cannabis the strain what I have it's around 16~% CBD and 0.5~ %THC I would add for example 10g of Cannabis and 100g of coconut oil and after that 3-3.5g would be perfect dose for my son (relaxed,focus etc) (30~mg CBD) so if I would make a tincture for example from 3g of cannabis (16% CBD 0.5%THC) and 4 Oz of 96% spirit ( I have my own distiller ) and reduce it to around 1oz, how many drops/ml I would have to use for the same effect like with coconut oil ?
