I’ve heard a saying: “The chains of habit are too weak to be felt until they are too strong to be broken.” And just like chains, some habits are stronger and deadlier than others. Conversely, healthy habits can be just as strong and powerful – but instead of bondage, they bring freedom to live our lives to the fullest.
In The Power of Habit, Charles Duhigg says, “Habits are a three-step loop: The cue, the routine, the reward. They become automatic beginning with a cue that triggers a routine and a craving for a clear reward. Craving is an essential part of the formula for creating new habits…You can never truly extinguish bad habits. So in order to change a habit, you must keep the old cue and deliver the old reward (that you are craving), BUT insert a new routine.”

DNA sequences for any human is approximately 99.9 percent identical to every other human. That means that only 0.1 percent of our genetic makeup is unique to us. Genes are functional units of DNA that make up the human genome. But don’t be fooled into thinking that 0.1 percent variation is insignificant. It is nearly 3 billion base pairs of DNA which boils down to 3 million differences that determine our physical features like hair and eye color and health risks or protection from diseases such as heart disease, diabetes – and addiction. Genes influence the numbers and types of receptors in peoples’ brains, how quickly their bodies metabolize drugs, and how well they respond to different medications.
The National Institute of Drug Abuse (NIDA) reports that family studies that include identical twins, fraternal twins, adoptees, and siblings suggest that as much as half of a person’s risk of becoming addicted to nicotine, alcohol, or other drugs depends on his or her genetic makeup. Scientists estimate that genes – including the effects environmental factors have on a person’s gene expression, called epigenetics – account for between 40 and 60 percent of a person’s risk of addiction.
Epigenetics – epi meaning “above” – is the study of functional, and sometimes inherited, changes in the regulation of gene activity and expression that are not dependent on gene sequence. This means exposures or choices people make can actually “mark” (remodel) the structure of DNA at the cell level. So epigenetic regulatory systems enable the development of different cell types (e.g., skin, liver, or nerve cells) in response to the environment. These epigenetic marks can affect health and even the expression of the traits passed to children. For example, when a person uses cocaine, it can “mark” the DNA, increasing the production of proteins common in addiction which is believed to correspond with drug-seeking behaviors.
MAT––Medication Assisted Treatment. Dr. Hillary Kunins, a clinical addiction expert, dispels the notion that treating an addiction patient with medication is simply exchanging one drug with another. Here is a link for a 2 min video where Dr Kunins offers a simple explanation of why physical dependence is not the same as addiction.
Here are the drugs that are currently in use for opioid addiction. Methadone has historically been used for heroin addiction, since the early 1970’s, when it was authorized by the FDA but restricted to daily dispensing clinics. Because it is an opioid-like drug, it has tended to only keep addicts alive, but never really able to be drug-free.
Nearly a half-century ago, buprenorphine was developed in England, where chemists were competing to invent a less addictive painkiller than morphine––it turned out to be far more addictive. It is now sold as Subutex and is an opioid partial agonist. An agonist is a chemical that binds to a receptor and activates it, producing a biological response. Like heroin, buprenorphine attaches to the brain’s opioid receptors creating euphoria, but it does not plug in as completely, so its effects are reduced. It is slower acting and longer lasting, attenuating the rush of sensation and eliminating the plummets afterward. But there is still potential for abuse and it can produce side effects such as respiratory depression.
Naloxone (Narcan, Evzio, injectable or intranasal spray) was patented in 1961, and is an opioid antagonist—meaning that it binds to opioid receptors and can reverse and block the effects of other opioids by displacing them from the opioid receptor sites in the brain.Whereas an agonist causes an action, an antagonist blocks the action of the agonist. It has been used in hospital “code arrest” emergency situations for decades. It was used on me before a surgery when I had been given too much anesthesia and was beginning to go in to respiratory arrest. It is being carried by emergency personnel and families of addicts because it can very quickly restore normal respiration to a person whose breathing has slowed or stopped as a result of overdosing with heroin or prescription opioid pain medications.
Naltrexone (Vivitrol, monthly injection) is an opiate antagonist that is more slowly released than naloxone. It is primarily used to manage opioid dependence or alcohol dependence and abuse by blocking neural pathways to the brain for dopamine neurotransmitters. It requires going through complete withdrawals and detoxification first because it will not work until opioids are out of the system. People who try to take opioids after taking naltrexone are at risk for opioid overdose and death since it takes using large amount of opioids to overcome its effects.
Suboxone––four parts buprenorphine, one part naloxone––was approved by the FDA in late 2002. Generally, although not accurate, when the word “buprenorphine” is used, people are referring to Suboxone. In addition to side effects from the buprenorphine in Suboxone, if a person has been taking it for a long time and they no longer receive it, they will suffer withdrawal symptoms similar to those suffered when stopping other forms of opiates. And, suffering from these withdrawal symptoms can worsen underlying mental disorders like anxiety or depression. At times, withdrawal can become overwhelming, which happened to jL, which sends patients into buprenorphine abuse and dependency. This has created a debate over the use of Suboxone and Subutex for addiction treatment.
A new study in The Lancet (January 27, 2018), sponsored by the National Institute on Drug Abuse (NIDA), compared the effectiveness of extended-release naltrexone with buprenorphine-naloxone in the US. The results were both promising and disappointing. While naltrexone is as effective as buprenorphine-naloxone once treatment begins, it is also significantly more difficult to actually start naltrexone because of the prolonged detox period—which can span more than a week—that buprenorphine-naloxone does not.
The biggest regret we have had since our son’s death in 2014 is that we did not take his doctors advice and have John Leif on Suboxone. There were many reasons that went into this decision, but the main one was that our health insurance did not pay the costs for any “mental health” coverage. Since we had so many years of our son’s relapses and recovery expenses, we decided to let him just “try harder” with the 12-steps and a sober living house. Sadly, it was not enough for a young man who desperately wanted to be clean and free of his enslaving addiction––he need MAT and we believe he would be alive today if he had been given that option.
