If you've ever taken the same dose of something as a friend and had a completely different experience, you're not imagining it. When it comes to THC, biology matters — and it turns out, women and men process cannabis in meaningfully different ways.
The research is still catching up (more on that in a moment), but what we do know is fascinating, empowering, and genuinely useful if you're navigating cannabis as a woman. Here's a breakdown of what the science says.
Why Women's Bodies Respond to THC Differently
The short answer: hormones.
Estrogen plays a surprisingly significant role in how women experience cannabis. It regulates an enzyme called fatty acid amide hydrolase (FAAH), which breaks down anandamide — the body's naturally occurring version of THC, sometimes called the "bliss molecule." Because estrogen levels fluctuate throughout the menstrual cycle, so does how effectively your body processes cannabinoids. This is why some women report that cannabis feels less effective right before or during their period, when estrogen levels are at their lowest.
Beyond estrogen, research published in Frontiers in Behavioral Neuroscience found that women have more sensitive cannabinoid receptors than men in key brain areas — and that those receptors change in sensitivity across the menstrual cycle. In other words, your response to THC isn't static. It shifts with your hormones.
Women Are More Sensitive to THC — Which Is a Good Thing (In the Right Dose)
Research consistently suggests that women tend to be more sensitive to the effects of THC than men, meaning they often feel the effects at lower doses. Studies in animal models have shown that female subjects respond more strongly to THC's effects, and human research has begun to reflect similar patterns.
For low-dose, intentional cannabis use — like microdosing — this is actually great news. It means women may need less THC to achieve the same effect, which supports the case for starting low and going slow. At Mary & Jane, this is exactly why our products are formulated the way they are: 1mg of THC is a meaningful dose, especially for women.
The flip side? Higher doses can hit harder, faster. Women report more dizziness than men at equivalent doses, according to research published in Neuropsychopharmacology. This is another reason microdosing makes so much sense for women — you get the benefits without tipping into uncomfortable territory.
THC and Mood: Women Feel It More
Cannabis has been shown to have more pronounced effects on anxiety and mood in women than in men. Research from the National Research Council of Italy found that cannabinoids show more significant sex-dependent effects in areas like anxiety and depression — and that these effects are more evident in females.
This has a practical upside: for many women, low-dose THC can be particularly effective for stress relief, social ease, and mood support. It's one of the reasons so many of our customers tell us that Sunny works for them in a way other things haven't.
The Hormonal Connection: Your Cycle Matters
Because estrogen directly influences the endocannabinoid system, your menstrual cycle can actually affect how THC lands on any given day. Research suggests that women may experience stronger effects when estrogen levels are higher — typically around ovulation — and milder effects just before and during their period.
What this means practically: if you're new to cannabis, it's worth paying attention to where you are in your cycle when you try something new, and not assuming your first experience is your baseline. Your body is not a fixed variable.
Women and the Munchies (or Lack Thereof)
Here's an interesting one: the "munchies" — that well-known appetite increase associated with THC — appears to be more pronounced in men than in women. Research from Washington State University found that increased appetite after cannabis use was actually the one area where men showed more sensitivity than women.
For women, THC can sometimes have the opposite effect on appetite. Some research has shown women are more likely to experience decreased appetite or nausea, particularly during withdrawal.
Why Most of the Research Has Been Done on Men
Here's the frustrating part: most cannabis research — like most drug research — has historically been conducted on male subjects. The hormonal variability of the female cycle was long considered a complicating factor, so researchers simply excluded women. The National Institutes of Health didn't recommend including women in clinical studies until 1993.
This means we're still playing catch-up on understanding exactly how THC affects the female body. As researcher Chandni Hindocha at University College London has noted, more research on women is critical so that women can properly weigh the pros and cons of cannabis use — just as they would with any other medicine.
The gap is closing, but it means women should approach cannabis with self-awareness and pay close attention to how their own body responds, rather than relying on dosing information developed primarily for men.
What This Means for You
If you're a woman curious about microdosing THC, here's what the science suggests:
Start lower than you think you need to. Women's heightened sensitivity means a smaller dose can go a long way. There's no prize for taking more.
Pay attention to your cycle. Your sensitivity may shift throughout the month. Keep a note of when you try something new and how it feels.
Choose intentional formats. Fast-dissolving melts and low-dose shots give you more control over your experience than edibles with unpredictable absorption.
Give it time. One experience doesn't define how cannabis will work for you long-term. Your body learns and adjusts.
The Bottom Line
Women and men experience THC differently — and that's not a bug, it's biology. Women tend to be more sensitive to THC's effects, experience more pronounced mood benefits at low doses, and are influenced by hormonal fluctuations in ways that men simply aren't.
Understanding this isn't about fear — it's about being informed. Because when you know how your body works, you can make choices that actually work for it.
That's exactly why we built Mary & Jane the way we did.
