Addiction is recognized as a disease by scientists, and now, finally, by most of us. It is no longer considered a moral weakness except by some who, like The Emperor and his new clothes, can’t see their own “moral weakness” but only those of others. Enough said.
As DNA research gains new insights by the day, we are learning how our DNA codes are regulated which will help in opioid treatments and prevention. Tiny differences in a persons DNA called single-nucleotide polymorphisms, SNPs, can indicate whether we have a higher or lower risk for addiction. Some of us have an opioid receptor gene with a single building block change that protects us against substance dependence in general and opioid dependence in particular. This is why the ‘opioid euphoria’ I wrote about doesn’t happen for us. But for others, variations in genes for three dopamine receptors – signaling pleasure – cause increased risk for opioid addiction.
Exposure matters in genetic expression, even across generations, according to how our body’s cells read them. In a recent study of opioids in rats (cited in the Ohio Society of Addiction Medicine’s blog on May 31, where much of this article is referenced from) the parents exposure to opioids changed the way their offspring read their DNA code, lessening their susceptibility to opioid addiction. This shows how one generation’s experiences can change the destiny of the next generation and although it hasn’t been studied in human substance abuse, it has been seen in other complex diseases like obesity.
Research suggests that people born into a culture of drug use may be more inclined to get and stay sober. Epigenetic’s may play a role. How this effects individuals born into a family with addiction issues like alcoholism, drugs, smoking, gambling, etc. is still unclear. For some of us, we observed behavior in our parents or relatives and made a concerted effort to not repeat it. Although our genes may have given us tendencies towards an addiction, a strong repulsion steered us away from it – and in my case, a strong dependence on the Lord.For our son, had we known how many of our relatives had addiction issues and how much power the addictive genes had, we would have been less permissive with our son in regards to drinking at an early age – and certainly more proactive once he was addicted to opioids. It might have changed the outcome for his life. I pray this information will help you, your family, and friends avoid the heartbreak we have had to live with.
One thought on “GENETICS AND OPIOID VULNERABILITY”
How insightful that the behaviors of one generation can influence the next generation. The analogy of obesity is brilliant. We can literally see it happening before our eyes. Addiction is more covert but it is heartening to know that blogs such as this exist and are being read. There seems to be a new awareness at the national level that we face a potentially disastrous problem that must be dealt with.
