Our human response to food and sex both involve survival issues. If you don’t eat you will die. You won’t die if you don’t have sex (you might think you will but you won’t) but getting pleasure from sex ensures we will seek it out and then there will be babies which ensures species survival. Drugs like alcohol, opiates, cannabis and stimulants work in the same brain pathway as those natural survival mechanisms.
The primary reward neurotransmitter is dopamine; food and sex stimulate dopamine release – and drugs also stimulate a high level of this release.
This occurs in our mesolimbic dopamine system which is below the level of thought. Our brain is hard-wired to respond to reward and the mesolimbic system doesn’t know what is okay or not okay. It just “likes”.
Once we like something we seek it out and start to have an anticipatory dopamine response to the thought of doing it again. Then we do it again, and again receive the reward. This is the fun part.
The not so fun part is that as we recreate that chemical reward we start to reduce the availability of dopamine and also serotonin (sense of well-being transmitter). Dopamine, in addition to being a reward transmitter, is also a connection transmitter. As the availability of these two are reduced (from overuse/overstimulation) our brain functions are reduced, particularly in the prefrontal cortex. Consequently, we have a harder time problem solving, decision making, and managing stress. Remember this is occurring in the same pathway as a food reward. When we are hungry we eat, when we are feeling stress or frustration we look for something to fix that and our limbic system will remember the reward we felt from the drug (including alcohol) and seek it out again.
The problem is that it works to change how we feel and we have just created a new brain pathway that becomes our primary response to stress. The neurobiological rule is the neurons that fire together wire together. Unfortunately, every time we do this we are weakening our natural stress response system (it’s like paying someone else to go to the gym for you) and more and more things feel stressful which creates more and more desire to use to escape from the stress.
At this point, the “addiction” (substance use disorder) is primarily emotional, as the use increases, we will start to develop physical dependency as well. With both of these as soon as the level of the drug starts to go down our stress response system activates and we start seeking more drugs.
In recovery, we essentially reverse the process and start to recreate and exercise our natural stress response system.
Rand T. is in long-term recovery, having been free from alcohol and other drugs since March 26, 1972. That freedom “from” has given him the freedom “to” do a lot of other things.
Recovery has also given him the energy to expand much of his work into helping others affected by substance abuse. He is a Canadian Certified Addiction Counselor and an Internationally Certified Prevention Specialist in drug and alcohol concerns (kids call him the Drug Teacher). He is very grateful that he has been able to do as much work as he has in the field of substance abuse.
Rand recommends three books in particular (their covers can be seen above):
- The Science of Addiction: From Neurobiology to Treatment;
- Never Enough: the neuroscience and experience of addiction;
- Unbroken Brain: A Revolutionary New Way of Understanding Addiction.
