I'm in no possesion of heroin and do not plan on taking any orally, ever. Now that I've stated that, what amount of heroin, of say average purity, would cause an overdose in a person with a small opiate tolerance? I don't know shit about oral heroin, but I'm guessing it's far less effective orally. Would it be safe to swallow half a gram? A friend of mine is wondering if her first time using heroin orally would even work, or get her high. I imagine it would just take a while to kick in. Any thoughts or suggestions are welcome. Thanks.
