Struggling to sleep through the night? You're not alone--and cannabis might have crossed your mind. A 2025 study found that cannabis-based products improved sleep quality in people with chronic insomnia over 18 months. But before you reach for that tincture, here's what you need to know.
The Good News: It Can Help--Sometimes
Cannabis works by increasing adenosine, a brain chemical that promotes sleep, while calming your brain's arousal system. For people with chronic pain, PTSD, or restless legs syndrome, cannabis may help you fall asleep faster and wake less during the night.
In the UK study, patients reported better sleep quality that lasted throughout the treatment period. They also experienced less anxiety and pain. About 30% of older adults in geriatrics clinics use cannabis specifically for sleep disturbance.
The Catch: Daily Use Changes Everything
Here's where it gets tricky. While occasional use might help, daily cannabis users are more likely to report sleep problems than non-users. Heavy use can lead to less overall sleep, longer time falling asleep, and frequent wake-ups.
Your body also builds tolerance over time. The 2025 study found that patients needed increasing doses as months passed, and benefits gradually faded. ""The American Academy of Sleep Medicine indicated in 2024 that evidence remains insufficient to recommend cannabinoids for routine treatment of insomnia,"" notes Dr. Ruchir Patel, medical director of the Insomnia and Sleep Institute of Arizona.
What Works Best After 50
If you're over 50, your body processes cannabis differently. Research shows that older adults may experience stronger effects because metabolism slows with age. Products with CBD (the non-psychoactive compound) or a 1:1 CBD-to-THC ratio tend to be safer than high-THC products.
Start with 2.5 mg of THC or less if you're trying edibles. Smoking cannabis carries heart risks, especially for older adults--daily users face a 25% higher risk of heart attack.
Talk to Your Doctor First
Cannabis can interact with common medications like blood thinners and may not be safe if you have heart conditions. But for some people with chronic conditions where other treatments have failed, it offers real relief.
You're already taking a smart step by learning this. If sleep problems persist, consider cognitive behavioral therapy for insomnia (CBT-I)--it's the gold standard treatment. Cannabis might be one tool in your toolkit, but it works best as part of a broader sleep strategy.
