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.

In 1735, Benjamin Franklin wrote a letter to his own newspaper, The Pennsylvania Gazette, where he used this now-famous phrase: An ounce of prevention is worth a pound of cure. He wasn’t referring to a pandemic or keeping your roof in good condition so it won’t leak or changing the oil in your car so you won’t ruin your engine or, my personal example, brushing your teeth to avoid tooth decay and gum disease.
When I was growing up in the 1960’s, brushing our teeth every day was a new habit for most Americans. Even though the toothbrush was invented in 1857, it wasn’t until after WWII that we got in the habit of regularly brushing our teeth. When I was young, I didn’t give much thought to personal care and it seems I didn’t brush my teeth often – I was too busy living life – which is why my two older sisters gave me the endearing nick-name “moss-mouth”. (FYI, I must have good teeth genetics because I didn’t have my first cavity until I was 30.)

In 2020, overdose deaths have increased worldwide, and by as much as 25% in the US. Deaths from acute intoxication have also increased dramatically. People are isolated and anxious, their treatment and recovery programs have been disrupted, and the illicit drug supply has become dangerous. Health officials believe that the majority of these deaths have occurred because hospitals are full and emergency services are overwhelmed with Covid-19 patients, thus removing the urgent, lifesaving care of overdose reversal that has been established in the past few years. Funding for all mental health services has also been diverted to pandemic care, which has complicated access to basic resources. Suicides are rising at an alarming rate.
A conversation that I believe is relevant to the current times came to mind this week. A lawyer asked Jesus “Who is my neighbor?” as he was trying to wriggle out of the command to “Love your neighbor as yourself.” Jesus told him about a man beaten and robbed while on a journey. As the man lay almost dead on the road, he was passed by several religious leaders who refused to help him. Then a man, who was not the same nationality or religion, came and bandaged and rescued him and paid for his care until he was well. Jesus asked the lawyer, “Which of these men proved to be a neighbor?” The lawyer replied, “The one who showed compassion.” Jesus responded, “Go and do the same.” *

For much of the world, Christmas and the holiday season this year has been nothing like our normal times of celebrating with family and friends. Togetherness is dangerous in most countries due to Covid-19. Yet, despite all the health and safety warnings, many have travelled and gathered with their loved ones. Why would people risk the well-being of themselves and their beloveds just to spend a few hours or days together?
Community. We all need it and ultimately cannot live without it. Communities may seem optional when all is well, but they become indispensable during hard times, whether personally or corporately. They can be small or large and most of us have several different sizes and types that we are part of: our family, school, sports, church, work, etc. What communities have in common are shared interests, beliefs, and needs, even while the individuals may have diverse characteristics. They are united and working towards a common goal and understand that they can achieve it because of, and with, the support and encouragement of others.
