Psych Effects
A neuropsychologist debunks a popular myth about substance abuse and explains how different personality types dictate certain drug addictions.
A case study from Boston tells of three high school girls who met each morning in their homeroom class before the first bell, when the seats were still empty, to take their daily hit. They were regular drug users who experimented with different illicit substances but always gathered in the same venue. Once these daily highs wore off, they moved on to something stronger and switched to the girls鈥 bathroom to be more discreet.
The first time they injected heroin into their veins, they experienced a powerful
rush like never before. Not only was the drug being introduced to their body chemistry
for the first time, but the change in venue also contributed to the overwhelming reaction.
And because there was no previous association between heroin and the new venue, this
new high was exceptionally euphoric.
After that initial exposure, the girls intended to replicate that first rush in the
same environment. But, because their brains now knew what to expect, and now associated
that high with that particular venue, their reactions became less intense and exciting.
While home from school one day, one of the girls injected herself in her own bathroom
with the same dose she usually took in the school bathroom. She died immediately of
an overdose.
This phenomenon is the primary focus of Seaver College psychology professor Jessica
Cail鈥檚 work鈥攖hat the mind-body connection influences the effects of drugs beyond mere
chemical quantities. A familiar setting can signal the brain to protect the body,
just as a brand new environment can overwhelm it鈥攔egardless of dosage levels.
鈥淭he original about addiction was that it was a matter of how much your body had been exposed to the
chemicals you had taken, and that it was a complete dose-response relationship,鈥 explains
the experimental neuropsychologist and drug addiction expert, 鈥渂ut shows that there is an environmental component. If you use in a certain environment at all times, you become more tolerant and less sensitive
to the drugs.鈥
Before joining the 老司机视频 faculty as an assistant visiting professor in 2009,
Cail dedicated most of her time to researching the psychopharmacology of addiction.
Her expertise in drug codependence developed out of a passion for the mind-body connection,
as she explored whether the mind could be used to heal the body and improve the success
of treatment without the side effects of medication.
Cail also studied the association between personality types and certain people鈥檚 attractions
to certain drugs, such as stimulants, depressants, and hallucinogens. 鈥淭here are all
these different classes of drugs ... and they鈥檙e all very different flavors,鈥 she
says. 鈥淚f they all have inherently addictive properties, why is it that this person
is attracted to this but not to that? It seems more often than not that it has to
match them in some underlying conditioned way.鈥
For instance, a person with an outgoing, thrill-seeking personality is more likely
to be attracted to stimulants, such as methamphetamine. On the other hand, a person
with a depressive personality may appreciate ecstasy, because it produces the same
happy chemicals as antidepressants. Furthermore, an anxious person who has trouble
self-soothing is already stimulated enough and is more likely to rely on substances
like alcohol, marijuana, and heroin to relax.
Cail has witnessed the validity of this notion beyond the lab. She recalls a conversation
with a friend who admitted to trying opium for the first time. When asked for feedback,
his nonchalant response about its lackluster gratification shocked her.
鈥淚 always thought opium is so inherently addictive that the person who tried it would
be hopelessly hooked on it,鈥 says Cail. 鈥淗e said he could 鈥榯ake it or leave it,鈥 but
he prefers marijuana, and that matches personality. He is anxious, and marijuana soothes him. It calms him down.鈥
Cail explains that most people are unaware of these external factors and continue
to define addictions by the amount of exposure to certain pharmaceuticals. 鈥淚 don鈥檛
think a lot of people give respect to the fact that we are connection-making machines
and that we associate cues,鈥 she notes. 鈥淧eople think it鈥檚 just the nature of the
drug, but it鈥檚 not. It鈥檚 bio-psycho-social.鈥
For those battling substance abuse, Cail emphasizes the importance of understanding
that addictions are chronic, relapsing conditions. 鈥淚t鈥檚 not a failure of someone鈥檚
willpower if they relapse,鈥 she explains, 鈥渢he same way we don鈥檛 look at somebody
whose cancer comes back after 15 years and ask, 鈥榃hat did you do wrong? Why did it
come back?鈥欌
鈥淚f we could break those associations, we might make a dent in the relapse rates,
which for heroin is between 86 and 98 percent. If we could make a tiny little dent
in that, we could probably help the cycle.鈥
