Im really curious if it is safe or not to IV the leftover resin from smoking heroin. I have a friend who left some of his toots (straws, empty pens) at my house. I water-whipped one yesterday (put hot water in straw and "whip it," smoke the waterish resin off foil) and I was very curious if the water-like substance was safe to IV. I feel like its a waste and way too messy to try and smoke a liquid off foil. Please let me know what you think.
