Dating norms are changing fast—and marijuana use is no longer the red flag it once was. According to recent survey data and scientific research, cannabis is increasingly viewed as neutral or even positive in romantic relationships, especially among younger generations. For many Americans, marijuana has quietly shifted from a taboo topic to a normalized lifestyle choice.

But what’s driving this shift, and how does marijuana use really impact dating, intimacy, and long-term relationships? Let’s break it down.

What Is Marijuana?

Marijuana—also commonly called cannabis—is a plant that has been used for centuries for medicinal, recreational, and industrial purposes. It comes from the Cannabis sativa or Cannabis indica species and contains naturally occurring compounds known as cannabinoids, which interact with the body’s endocannabinoid system.

The two most well-known cannabinoids are:

• THC (tetrahydrocannabinol): The primary psychoactive compound responsible for the “high”
• CBD (cannabidiol): A non-intoxicating compound often used for wellness and therapeutic purposes

The effects of marijuana can vary depending on the strain, dosage, method of use, and individual tolerance.

How Does Marijuana Work in Our Body?

Marijuana works by interacting with a natural regulatory network in the human body known as the endocannabinoid system (ECS). This system plays a key role in maintaining balance—also called homeostasis—across many physical and mental processes, including mood, sleep, appetite, pain, and memory.

The Role of the Endocannabinoid System (ECS)

The endocannabinoid system is made up of three main components:

• Endocannabinoids: Naturally produced compounds in the body that resemble cannabinoids found in marijuana
• Cannabinoid receptors: Primarily CB1 and CB2 receptors found throughout the brain, nervous system, and immune system
• Enzymes: Responsible for breaking down endocannabinoids once they’ve done their job

This system helps regulate how the body responds to stress, inflammation, and other internal changes.

How THC Affects the Body

THC (tetrahydrocannabinol) is the main psychoactive compound in marijuana. It binds primarily to CB1 receptors in the brain, which can lead to:

• Feelings of euphoria or relaxation
• Altered perception of time and senses
• Increased appetite
• Reduced pain perception
• Changes in memory and concentration

Because THC directly mimics the body’s own endocannabinoids, it can strongly influence brain activity.

How CBD Works Differently

CBD (cannabidiol) interacts with the body in a more indirect way. It does not cause intoxication and may:

• Help reduce anxiety and stress
• Support better sleep
• Modulate the effects of THC
• Influence inflammation and pain responses

CBD works by affecting multiple receptor systems, not just cannabinoid receptors, which is why its effects feel more subtle and balanced.

How Many People Use Marijuana Today?

Marijuana use is widespread in the U.S., which helps explain its growing acceptance in dating culture.

A new survey by Drug Rehab USA, which questioned 1,000 adults with recent dating experience, found that:

• Only 1 in 4 people consider marijuana use a dating red flag
• Four in five millennials don’t mind if their partner uses cannabis
• Seven in ten Gen Z adults feel the same

Daily cannabis use is also common:

• 22 percent of daters say their partner uses marijuana daily
• Among Gen Z couples, that number rises to 35 percent

With usage this prevalent, marijuana is increasingly seen as part of everyday life rather than a relationship risk.

Why Do People Use Marijuana?

People use marijuana for a variety of reasons, many of which go beyond recreation. Common motivations include:

• Stress relief and relaxation
• Improved sleep
• Pain management
• Enhanced intimacy or emotional connection
• Increased creativity or focus

In romantic relationships, some couples report that cannabis helps them feel more relaxed, present, and emotionally open—factors that can strengthen bonding.

Marijuana Use Isn’t the Biggest Dating Turn-Off

When compared with other substances, marijuana ranks relatively low as a dating concern.

The same survey found:

• 38 percent see cigarette smoking as a red flag
• 73 percent view high-risk illicit drug use as a dealbreaker
• 60 percent are concerned about prescription drug misuse

Alcohol was the only substance viewed more favorably than marijuana, with just 22 percent considering drinking a red flag. 

How Different Methods of Using Marijuana Affect the Body 

How marijuana is consumed affects onset, duration, and overall experience. Here’s a comparison of common methods:

Method of Use	Onset Time	Duration	Notes
Smoking/Vaping	Minutes	1–3 hours	Effects are felt within minutes but may wear off sooner
Edibles	30–90 minutes	4–8 hours	Effects take longer to start but last longer and may feel stronger
Oils/Tinctures	15–45 minutes	3–6 hours	Offer more controlled dosing and moderate onset times
Topicals	10–30 minutes	Localized, few hours	Affect localized areas without producing a “high”

How to Use Marijuana Responsibly in Relationships

How marijuana is used often matters more than whether it’s used at all. Responsible cannabis use typically includes:

• Moderate dosing
• Clear communication with a partner
• Avoiding dependence
• Respecting boundaries and preferences

Despite rising acceptance, stigma still exists. Only 13 percent of survey respondents said they would include a photo of themselves smoking marijuana on a dating profile—suggesting many users still choose discretion.

Can Cannabis Improve Relationship Intimacy?

For some couples, cannabis use appears to enhance closeness.

• 24 percent of respondents said substance use improved intimacy, making relationships feel more relaxed or passionate
• 68 percent said their relationship would not be stronger if their partner stopped using marijuana
• 10 percent believed quitting could actually cause emotional distance

Survey analysts concluded that cannabis is increasingly viewed as “socially connective” rather than disruptive in modern relationships.

Marijuana and Sexual Satisfaction: What Research Shows

Scientific research supports many of these real-world experiences.

Recent studies have found that marijuana use may be linked to:

• Increased sexual desire and arousal
• Lower sexual distress
• Improved sensitivity and satisfaction

A 2024 scientific review found cannabis may help improve symptoms of female orgasmic disorder. Another study reported that marijuana enhanced sexual enjoyment more consistently than alcohol, which tends to “facilitate” sex but not deepen satisfaction.

Marijuana Use in Teens: A Different Conversation

While adult cannabis use is increasingly accepted, marijuana use in teens remains a public health concern.

Adolescents’ brains are still developing, and early cannabis exposure has been linked to:

• Impaired memory and attention
• Increased risk of anxiety or mood disorders
• Lower academic performance

Most health experts emphasize that teen marijuana use should be approached very differently than adult use, with education, prevention, and parental guidance playing key roles.

Long-Term Effects of Marijuana Use

The long-term effects of marijuana use can vary widely depending on frequency, dosage, and age of first use.

Potential long-term effects include:

• Tolerance or dependence in heavy users
• Respiratory irritation from smoking
• Cognitive effects with frequent, high-dose use
• Possible mental health impacts in vulnerable individuals

Research also suggests that lower doses may offer benefits—especially for intimacy—while higher doses could reduce desire or performance. 

How Long Marijuana Stays Active in the Body

Once consumed, cannabinoids are metabolized in the liver and stored temporarily in fat cells. Factors that influence how long marijuana remains active include:

• Frequency of use
• Dosage
• Body fat percentage
• Individual metabolism

Effects may last from a few hours to an entire day, while trace amounts can remain in the body longer. 

Understanding Marijuana Laws

Marijuana legality varies widely depending on location. In the United States, it remains illegal under federal law as a Schedule I controlled substance, but many states have legalized it for medical use (around 40 states) or recreational use (24 states plus D.C.). This creates a complex system where possession, sale, or cultivation may be legal under state law but still prohibited federally. Laws are constantly evolving, so it’s essential to stay informed about local regulations and restrictions, as explained in detail by USAFacts.

Possible Side Effects of Using Marijuana

Marijuana can affect people in different ways depending on the dose, frequency of use, method of consumption, and individual tolerance. While many adults use cannabis without major issues, it’s important to understand the potential side effects—especially with frequent or high-dose use.

Common Short-Term Side Effects

These effects are usually temporary and may occur shortly after use:

• Dry mouth and dry eyes
• Drowsiness or fatigue
• Impaired memory and concentration
• Slower reaction time and coordination
• Altered perception of time and senses
• Increased appetite

Some users may also experience lightheadedness or dizziness, particularly with higher doses.

Mental and Emotional Side Effects

Marijuana can influence mood and mental state, especially when THC levels are high:

• Anxiety or nervousness
• Paranoia or restlessness
• Mood swings
• Confusion or racing thoughts

In some individuals, especially those sensitive to THC, marijuana may temporarily worsen anxiety or trigger panic-like symptoms.

Physical Side Effects

Certain physical effects may occur depending on how marijuana is used:

• Increased heart rate
• Red or irritated eyes
• Coughing or throat irritation (from smoking)
• Nausea in some users

Smoking marijuana can also expose the lungs to irritants similar to those found in tobacco smoke.

Possible Long-Term Side Effects

With frequent or long-term use, some individuals may experience:

• Reduced attention, memory, or learning ability
• Tolerance, requiring higher doses for the same effect
• Dependence or difficulty cutting back
• Changes in motivation or energy levels

Long-term effects can vary widely and are more likely with heavy or early-onset use.

Effects on Mental Health

In people with a personal or family history of mental health conditions, marijuana use may be associated with:

• Worsening anxiety or depression
• Increased risk of psychotic symptoms in vulnerable individuals

These effects are not universal but are important considerations.

Side Effects in Teens and Young Adults

Because the brain continues developing into the mid-20s, marijuana use in teens and young adults may increase the risk of:

• Memory and attention difficulties
• Lower academic performance
• Emotional regulation challenges

Health experts generally recommend avoiding marijuana use during adolescence.
