Heroin addiction is one of the most destructive and painful addictions in the world. Produced from the poppy, heroin transfers a semi synthetic form of morphine, usually by way of injection. Administration of heroin gives the user euphoric feelings, which differ depending on the area that the heroin is injected. If the heroin is injected intravenously effects are felt within 7 to 8 seconds. Muscular injections are slower with full effects being felt at 5 to 8 minutes.
