The crisis of addiction to prescription opioids — and the accompanying grave statistics about overdose and related deaths — has overshadowed another class of prescription drugs that has proven to be extremely dangerous and addictive: benzodiazepines.
These prescription medications, often prescribed to treat anxiety, depression and a range of other mental and physical disorders, have a lot of similarities to opioids in their addictive nature and likelihood to be abused, even when a person is originally prescribed them.
In this piece, we’ll discuss the ins and outs of benzo addiction, including how addictive drugs of this class are, the long-term effect on the body and when treatment is necessary.
What Is Benzo Addiction?
Like addiction to any other drug, addiction to a benzodiazepine means that your body and brain begin to function as if they need the drug at all times. At this point, if a person stops taking benzos, their body will go into withdrawal and they would experience powerful cravings for the drug (or another drug of the same type).
To understand how addiction happens from benzo use and abuse, it makes sense to talk a little about why they’re prescribed. In the 1950s, when the first benzodiazepine was developed, it was supposed to be a less addictive (and less dangerous) alternative to the previous standard treatment: prescription barbiturates. Consequently, benzos are now far more likely than their predecessors to be prescribed for depression, anxiety, panic disorders, bipolar disorder and other mental health conditions.
Benzodiazepine abuse affects the body in a similar way as heavy alcohol consumption does. When the drugs are consumed, molecules bind to GABA receptors in the brain, stimulating the removal of dopamine inhibitors. Dopamine, a neurotransmitter that causes feelings of pleasure and euphoria, is released in high concentrations, decreasing the negative emotions that cause depression, anxiety and other mental health conditions.
Simply put, benzos make the user feel good, which is why they’re candidates for abuse and, over time, addiction.
How Does Benzo Use Turn Into Benzo Addiction?
The invention of benzos as a safer alternative to barbiturates in treating mental health disorders like depression and anxiety was, in general, a success. However, as of 2013, benzos were involved in 31% of overdose deaths due to the massive availability of prescriptions as well as users’ tendency to mix benzos with other drugs.
Because of their addictive potential, benzos are often prescribed for a shorter term than other drugs. If a person is diagnosed with an anxiety disorder, for example, a doctor will likely start them on benzodiazepine to address acute symptoms of the disorder at the same time as an SSRI antidepressant, which takes a longer time to present its effects.
Like other addictive prescription drugs — opioid pain pills, for example — benzos are often used as prescribed at first but then cause the user to become dependent on them. This is because dependency and even addiction can take hold more quickly than patients are taken off of their prescriptions. It’s recommended that benzo prescriptions only be written for one to two weeks because symptoms of withdrawal from the drug can be experienced after only three or four.
