so i followed robert bergman’s instructions on how to make a tincture for vape pen juice:
i cut up 6grams of 20% THC weed and put it in a small mason jar and covered it with 3oz of 151proof grain alcohol for 14days, shaking/stirring it every day. then i strained it and got close to 3oz of extract since not much evaporated with the jar lid on.
question#1: i’ll be mixing my tincture with VG to use in an ecig. what percentage of tincture-to-VG should i start with? i’d like to experiment a little and find what strength i like before i make the whole batch. my ecig cartridge holds 0.75mL.
question#2: is there a specific way i need to mix my tincture and VG so the two will assimilate or do they easily take to each other?
question#3: i’m not super excited about vaping 75.5% grain alcohol and whatever else is in there into my lungs. so what happens if i leave my tincture out to evaporate? if it totally evaporates will there be some kind of THC substance left?
