As
a recovering addict, several things can lead one to relapse. Some of these
things include being exposed to triggers for cravings, such as drug
paraphernalia and friends that one used to associate with when using the
substance. Furthermore, even things like the music one used to listen to when
high could trigger cravings, and ultimately, relapse (Olson).
However,
did you know that there is a biological basis for these drug-related cues triggering
cravings and ultimately relapse? In Dr. Stephan Steidl’s speech in which he
discussed some of his research, he shed some light on some of the processes that
makes drug-related cues elicit cravings. He discussed his study in which they
recorded electrical brain activity in monkeys. They had the monkey sitting in a
chair with an electrode in its midbrain. They started giving the monkey a
reward, a squirt of apple juice in the mouth, and noted that prior to the
reward, dopamine neurons fired normally, and after the reward, there was more
firing (Steidl).
However,
they started introducing conditioned stimuli. The squirt of apple juice was
then always preceded by a tone or light. They found that after doing this, they
were not getting a measurable increase in firing in response to the reward, but
instead as a response to the reward predictor. When introducing only the tone or
light, the conditioned stimulus, there was an increase in dopamine. In that
sense, reward predictors elicit “craving” and precipitate relapse (Steidl).
This is why paraphernalia associated with use of drug, and drug predictive cues
often lead to cravings and relapse.
The
news article from Medical Daily explains how according to the NIDA, 40 to 60
percent of drug or alcohol addicts do end up relapsing, and that the chronic
nature of addiction “makes relapse a likely road for recovering addicts” (Olson).
However, the article made it a point that cutting out certain drug-related cues
that can trigger cravings as described by Steidl’s research, may allow patients
to have an easier time fighting their addiction. They suggest that drug
counselors should focus more of their attention on “detaching patients from
their cigarette-smoking partners, and less attention on hiding lighters from
their sight” and that if that is done, “relapse rates could drop” (Olson). Dr.
Steidl’s research explains the biological process in which these drug-related
cues can trigger cravings and relapse.
