Tinctures are a great DIY project. At a minimum, you can make a tincture with a jar, alcohol, a strainer, and cannabis flower. Tinctures are low calorie alternative and will last for many years when stored in a cool, dark location.
How can you take tinctures?
Tinctures are usually taken by putting a few drops under your tongue (sublingually). When taken this way, the arterial blood supply under your tongue rapidly absorbs the THC. That being said, you can always swallow the tincture in a drink or food, but it will be absorbed more slowly by your liver.
How fast is the onset?
When dosing a tincture sublingually, expect to feel the effects in 15 to 45 min and reach your peak high at about 90 min.
How long will I feel the effects?
Expect to be high longer that when you smoke or vaporize, but shorter then when you eat a butter or oil based edible.
