Making your own medical marijuana tincture is a fairly easy process. 
“Medical marijuana can come in many forms. A patient can choose his or her preferred method of consumption. Glycerin-based tinctures are very versatile and a great alternative to smoking, vaporizing, or strong-tasting alcohol-based tinctures.
A quality glycerin cannabis tincture can be mixed with any food or beverage and allows patients who need fast relief to place the tincture directly under their tongue. Not only does this method bring fast relief, it also allows patients to control their dosage in a similar manner to smoking their medicine. Although it takes a little time, making your own medical marijuana tincture is a fairly easy process.
Here’s what you will need to get started:
– A crock pot with a “low” and “warm” setting
– Cheesecloth
– Large bowl
– Latex gloves
– Wooden spoon
– 1 gallon of food-grade vegetable glycerin
– 1/4 -1/2 lb of medical marijuana or high quality trim material
– Glass storage container (not pictured)”
