In this Stuff You Should Know episode, the hosts examine the debate surrounding whether a "love drug" could or should exist. They discuss the neuroscience of love's different stages, from lust and romantic attraction to long-term attachment. The episode explores how existing drugs like oxytocin and MDMA influence feelings of bonding and attachment, as well as the ethical concerns around chemically-induced love.
While some argue that drug-induced love lacks authenticity, others posit that such substances could benefit struggling relationships by enhancing emotional bonds. However, the potential for coercion and misuse remains a major ethical concern over whether a love drug could be developed and regulated responsibly.

Helen Fisher segmented the experience of love into three distinct yet global stages: lust, romantic attraction, and attachment. According to Fisher, each stage involves specific hormones and neurotransmitters such as [restricted term], estrogen, [restricted term], [restricted term], and [restricted term].
While Fisher's model proposes love as a unified experience, psychologist Lisa Diamond argues for a "split attraction model" where sexual and romantic attraction are biologically distinct. However, Fisher's three-part chemical framework still resonates with cultural narratives of love.
Substances like alcohol, [restricted term], and [restricted term] are known to indirectly impact feelings of love and attachment by facilitating experiences that promote [restricted term] release.
Philosophers like Julian Savulescu and Brian Earp suggest using intranasal [restricted term] and MDMA therapeutically to enhance or restore attachment in relationships, drawing from research showing these drugs can induce bonding. However, there are concerns about misuse and coercion.
Some philosophers argue chemically-induced love lacks authenticity. Peter Harrison Kelly asserts drugs only enhance associated feelings, not attachment itself. Others suggest if love is chemically mediated, it's not "real."
Countering skeptics, bioethicist Haichim Nar believes the positive effects of these drugs justify use, even if the resulting emotion isn't organic. These drugs could help appreciate a partner's lovable traits and support healthy relationships.
Critics warn of potential abuse, like in conversion therapy. There are doubts over whether regulation could prevent coercive misuse of love-enhancing drugs.
1-Page Summary
Exploring love's complexities within the brain, Helen Fisher’s work divides the experience into three distinct stages, which are further illuminated by the debate between those who see love as a single phenomenon and those who identify divergent components within it.
Helen Fisher dedicated her career to studying love, which she segmented into lust, romantic attraction, and attachment. These stages are suggested to exist globally as the conventional understanding of romantic love, and they can occur in or out of sequential order.
Fisher identifies key chemicals driving the stages of love. The first stage, lust, is governed by [restricted term] and estrogen, which are fundamental in sexual desire. The second stage, romantic attraction, is marked by a surge of [restricted term] and [restricted term]—heightening arousal and focus—and intertwined with cortisol and serotonin, which play roles in regulating mood and maintaining focus on romantic interests. The third phase is attachment, fostering long-term commitment, which involves [restricted term], known to enhance empathy and trust, and vasopressin, a critical hormone for long-term bonding, particularly in males.

The neuroscience and neurochemistry of love and relationships
In the realm of emotions and relationships, the concept of "love drugs" is emerging, referring to substances that could potentially influence feelings of love and attachment. While some substances like alcohol, [restricted term], and [restricted term] are already known for their indirect effects on social bonding, there's a growing interest in the therapeutic applications of drugs like intranasal [restricted term] and MDMA for enhancing or restoring relationships.
Alcohol has long been used to relax individuals, making them more sociable, especially in potentially romantic scenarios such as a first date. [restricted term] and [restricted term] supplements, often employed to boost libido or treat erectile dysfunction, are seen as facilitating activities that could lead to feelings of love by fostering circumstances that promote the release of [restricted term], a hormone associated with love and bonding.
These drugs might indirectly act as "love drugs" by enabling experiences that could lead to increased [restricted term] levels, reinforcing emotional attachment and closeness between individuals.
Philosophers and ethicists like Julian Savalescu and Brian Earp have explored the concept of using therapeutic drugs to enhance feelings of love and attachment. They suggest that drugs like intranasal [restricted term] and MDMA could be used to maintain or revive sentiments of connection in long-term relationships, particularly when natural attachment has diminished due to challenges such as autism or ADHD.
In lab experiments, prairie voles were given [restricted term] and vasopressin, which induced bonding similar to what naturally occurs through mating. Correspondingly, [restricted term] as a nasal spray has been proposed for various trust-building applications, such as hostage negotiations and riot control. Despite not being expected to cross the blood-brain barrier, this [restricted term] spray has shown effects on people's feelings.
MDMA, which promotes the release of [restricted term] and other neurotransmitters, was once studied for its therapeutic use in couples therapy until it was banned in 1985. Its ability to make people feel more connected and find depth in conversations has led to its experimental use in therapy for PTSD, as well as anecdotally reported long-lasting effects on attac ...
Existing "love drugs" and their potential therapeutic applications
Philosopher Peter Harrison Kelly challenges the idea that attachment can be reduced to hormonal drive, asserting that drugs cannot create true attachment as they only enhance feelings associated with attachment rather than boosting attachment itself. Sven Neilhjelm, a German ethicist, adds to this perspective by suggesting that if love is chemically mediated, it might not be considered real or natural. Josh Clark supports this sentiment by mentioning that love is intrinsically good in itself, and producing it chemically could compromise its authenticity. Chuck Bryant echoes similar thoughts, recognizing that chemicals play a role in love but there's an undefinable aspect that can't be controlled by medication.
Counter to skeptics, Haichim Nar, a bioethicist, believes that the positive effects of these drugs can justify their use, even if the "love" they produce is not organic. Nar suggests that these drugs might lead to appreciating someone's characteristics that make them lovable, challenging the notion that the chemically-induced emotion isn't valid.
The drugs are compared to socially acceptable activities engaged by couples to rekindle relationships, suggesting that the drugs serve a similar but more scientifically targeted purpose. The longevity of relationships, once believed to be counter-evolutionary, is now seen as beneficial for mental, physical, and overall well-being—benefits that love-enhancing drugs could support. The debate raises the point that just because certain behaviors were not part of our evolutionary past doesn't mean we shouldn't embrace them socially, applying this concept to the use of drugs for maintaining relationships.
Despite the potential benefits, there are significant concerns regarding the ethical implications and potential for the misuse of love ...
