That sounds likaa pretty small amount. But it takes weeks to months to make good tincture. You should use grain alcohol. Get the 190 proof Ever Clear or Clear Spring if it is available in your area. I add the weed then shake it and leave it for a couple of months. Then strain the alcohol from the weed add some new weed and leave that for a couple of more months then strain and use that.

Just a drop under the tounge will get you high in a couple of minutes. I usually mix it with a drink.
