Make an oil tincture from MCT oil and rosin. You can make it whatever strength you like. It works well, and doen't burn the mouth the way an alcohol tincture does. Also, it seems to me at least that starting with rosin makes for more consistent dosing. First because the variance between individual buds is eliminated, and second because the amount of THC (and other cannabinoids) seems to be relatively consistent in rosin, so strength is nicely related to the rosin/oil ratio. All just based on my experience, which is far less than what other peeps here have.
