Heroin Research Shows Genetic Components of Addiction
Sunday, November 23rd, 2008Just when you think we know all there is to know about addiction, think again. Research goes on year round, continuing to crack genetic clues and find optimal ways to treat difficult drug addictions. Here’s a summary of some interesting and interconnected research done this past couple of years on heroin addiction. Anyone going to a drug rehab center in the future will be impacted by these findings.
Genetic Research On Heroin Addiction Reveals Options For Custom Detox Drug Treatment
Turns out that even some small genetic differences put some Caucasian people at a higher risk for heroin addiction. According to one of the authors, some of these few genetic changes can raise the risk for Caucasian people but possibly have no effect in different racial populations.
This poses an interesting but challenging opportunity for the medical field. It allows the chance to determine and develop individualized dosages of methadone and other opiate withdrawal medications. However, this also makes drug treatment that much more complex to determine and administer.
The drop-out rate for methadone programs is a high 62%. The dropout rate is attributed to addicts still having strong withdrawal symptoms despite the medication. Researchers seem to be taking this rate and the recent genetic studies as a clue about methadone “dropouts” genetics not being matched well with their medication dosage.
Heroin Addiction Uses Information Super Highways in Your Brain
Neural pathways are like highways in your brain for messages. They start out something new that you try, like a new exercise move or trying a different way to work. If this only gets used once or a few times, it may die out and not become an established path. The more it is used, the stronger the path becomes until it potentially becomes more like a solid highway.
Such pathways exist for all kinds of activities and patterns. One of these is called “reward pathways.” As the name suggests, this type of pathway involves certain brain chemicals and parts of the brain associated with anything you might see as rewarding. Reward paths make it more likely that you will do something again and again. This works the same way for things that are positive and healthy or for things that are risky and harmful.
You get excited when you go to your first football game, you are likely to do it again because you enjoyed the sensations. You like the feeling of independence and the physical mastery of driving as a teenager, so despite the risks you are likely to do it again. You try heroin and it lights up the pleasure centers of your brain, you are (unfortunately) likely to do it again.
Recent research on heroin suggests that a specific neurotransmitter (brain chemical) receptor in the brain is connected with reward pathways as described above. They apparently play a part in a person’s motivation to keep using heroin. The door is now open for developing medication to block this receptor and hopefully curb drug-seeking behaviors. This sheds a ray of hope for people leaving drug rehab and establishing their relapse prevention plan.
Drug Rehab Benefits From Continuous Addiction Research
Heroin is an amazingly powerful drug. Addicts leaving drug rehab centers need all the support and help they can get to manage their addiction. Thankfully, scientists around the world are discovering clues about the human body that may help the drug treatment process by improving relapse prevention.
