A marijuana tincture is a solution of alcohol and THC. Tinctures are a much more concentrated version of the traditional drink known as "The Green Dragon.". The higher the ratio of alcohol to weed is, the greater the potential for THC to be drawn out is. And since all that extra grain alcohol isn't appetizing to anybody but mental patients,I always evaporate off the excess.
How do I make it?
(ixnay007) You need to use PGA (pure grain alcohol) because the more water present in your alcohol, the more nasty stuff ends up in your green dragon like tanins, etc (it'll end up brown).
Note: make sure you're doing this on LOW heat, as you don't want to burn yourself by boiling the alcohol. Also be aware that this process is very stinky, and will make your house smell like weed for a couple of hours, unless it is extremely well ventilated. That's why I always do this in my backyard with a hotplate and an extension cord.
(ixnay007) When you have green dragon that you aren't going to drink, you need to remember to store it in cool very dark places, as alcohol-extracted THC is fairly unstable, and will degrade quickly in light or when exposed to heat.
You can drink it straight, or mix it. The potency is high, and is similar to eating oil-extracted THC, yet is different at the same time. You'll just have to try it!
