A tincture can vary in effect depending on if it is used sublingually, orally or used to infuse just about any dish you want. Sublingual is usually the fastest acting but all tinctures are faster acting than your typical edible. So you wonâ€™t have to wait two to three hours just to find out your medicine didnâ€™t work. You should be able to tell shortly after a dose of tincture whether or not youâ€™ll need more. Despite their convenience, cannabis tinctures are rarely talked about. Prior to prohibition, it was the most common form of medical cannabis in the United States.
