Love Potion #1: New drug could control love’s presence

For those looking for love, a recent scientific discovery may soon help guide Cupid’s arrow

Couple about to kiss

While these students seem to enjoy Valentine’s Day, others may prefer an anti-love vaccine to avoid the depression that sometimes accompanies single life.

This time of year, people of all ages are either on Cloud Nine, dismissive of the consumerist event called Valentine's Day or constructing voodoo dolls of past significant others.

For those who fall into the category of love haters, a new drug that can make people fall in and out of love is in the early stages of testing, and its development may be a one-way ticket to controlling romantic emotion.

The idea for this drug — and prospective vaccine — is based on the research of neuroscientist Dr. Larry Young. Young worked with animals called prairie voles, which are among the small minority of mammals — less than five percent — who share humans' propensity for monogamy.

When a female prairie vole's brain is artificially infused with oxytocin, a hormone that produces neural rewards comparable to those created by substances such as nicotine and cocaine, she will quickly become attached to the nearest male. A related hormone, vasopressin, creates urges for bonding and nesting in male voles.

The research also revealed that male voles with a genetically limited vasopressin response were less likely to find mates. Young's corresponding research found that men with a similar genetic tendency were less likely to commit.

Theoretically, if used to its fullest potential, the drug could effectively harness these chemicals and be used to make people experience emotions of love. Conversely, it could also be used to prevent people from feeling such sentiments simply by receiving an injection of the substance.

But the process isn't as simple as a quick oxytocin or vasopressin booster or blocker, according to Sheldon Krimsky, professor of urban and environmental policy and planning.

"In animal studies, we can manipulate these things at a chemical level. [But] animals don't have a culture, history, established relationships or live in complex environments," Krimsky explained. "You cannot assume that what you get from the controlled experimental system will translate to a human level. Who you are going to love and mate with is a complicated situation that cannot be pinned down to a hormone shift."

Even if Young were able to construct a drug that worked perfectly for humans, there are a number of ethical questions that come into play when dealing with an emotion as fragile and peculiar as love.

The implications of the drug could be as simple as putting the spark back into a dull marriage and getting over a tough breakup; concerns could be immense, however, if the drug's power fell into the wrong hands.

"I don't think you can exploit other people's emotions like that," freshman Kavitha Narra said. "I'd rather it develop naturally and know that the person actually likes me back."

Krimsky does not support the vaccine either.

"Love is so complicated, and there always seems to be an inexplicable X factor," he said. "The idea of trying to reduce it to some kind of chemical potion or to a list of shared beliefs is nonsense. It doesn't work. If we don't have a concept for what love is for an animal, how can we take it from an animal source and translate it to something so nuanced as human love?"

He explained that if the vaccine does enter the clinical picture, deciding how and when to use it will still be a major decision.

"[Just because] a vaccine makes people fall in love, [it] doesn't mean they will have a good relationship," he said. "It would be some kind of strange science fictional world if we could create a vaccine that facilitated marital bliss … there is no way to create simple solutions to such extreme complexity."

That extreme complexity is something humans experience everyday, whether it be with falling in love for the first time or struggling to keep a marriage alive.

"A vaccine that can make people fall in and out of love goes against everything we are taught to believe about love," freshman Emily Cox said. "[Modern philosopher] Erich Fromm says that our deepest desire is to overcome our prison of separateness. If we don't, we'll go insane. We need love more than we need anything else. Take that ability away, and we lose our purpose as people. Conversely, if love is as easy as a poke in the arm, we lose the journey and struggle to obtain it, and then is it really worth having?"

I think the real benefit here, is that we could maybe learn a few new things about depression and adiction in the human brain. I don't think these chemicals could make or cure love, but they may have a serious benefit to those who have mental illness.

The anti's here fail to note the situation that a marriage is beautiful and happy everything but lacks love. One chemical stimulant later and bam, you have love. They also fail to mention what happens to the poor people who can't feel love. It was mentioned in the article, but some people lack the natural chemical or lack it in proper quantities. What if we could cure their disease and we don't want to because of "ethical complications"? Ethical that.

Love is nothing magical that is just your environment talking. Love is a chemical response.

Thought that drug was called "roofies" :)

Anyone wonder why this is in a student newspaper? The study was not conclusive and even if it did work on prairie voles that does not mean the same effect would happen for humans. While some statistics in the study were statistically significant not all of them were. Just another example of irresponsible reporting. You're at Tufts, not the National Enquirer! Then again, it is Tufts...

I have a few crazy ex's I love to hit with the vaccine.....maybe more than once in the case of my last ex.

This drug has been available for thousands of years. It's called alcohol.

On a serious note, if both parties were to agree to treatment it seems like it would be a good fit for marriage counseling or relationship counseling.

Warning, do not take this before a zoo trip! I caused quite a scene when they pulled me out of the orangutan cage.

Tried it! Don't work. I mixed my diet pills with the love drug and a fat girl hugged me by accident!

I would -gladly- take this drug myself, if it meant that I wouldn't go home and gnash my teeth at my wife, in front of my kids. Ignorance isn't bliss, but in my case, I am incapable of forgiving some things... I'd like to be able to love again in spite of that.

That's awesome. No more chloroform and rags necessary to get a date. I hated having to drag the chick to an alley. Now, they'll just go for it without being unconcious!
