Winter nights in Vermont run long. By mid-January, the sun sets before five, and the dark stretches on for fourteen hours or more. If you've found yourself lying awake at 2 AM, watching the cold moonlight on snow-covered fields, you're not alone. Sleep troubles affect roughly one in three adults, and plenty of Vermonters have started wondering whether cannabis might help.

The honest answer? It's complicated. The research is genuinely mixed, and what works for some folks doesn't work for others. But there are some things worth knowing — real information that can help you make thoughtful decisions about whether cannabis belongs in your evening routine.

What the Research Actually Shows

A 2025 study published in PLOS Mental Health followed insomnia patients using cannabis-based products over 18 months. The findings were encouraging: participants reported sustained improvements in sleep quality, reduced anxiety, and better overall wellbeing. Most side effects were mild — dry mouth, occasional fatigue — and nothing life-threatening.

But here's where it gets nuanced. A separate meta-analysis of over 1,000 patients found that cannabinoids improved subjective sleep quality, but the benefits were driven primarily by products containing THC, not CBD alone. Meanwhile, research from the University of Michigan found that about 18% of young adults use cannabis to fall asleep — yet the researchers cautioned that long-term, regular use may actually worsen sleep problems over time.

The takeaway isn't that cannabis doesn't work. It's that how you use it matters as much as whether you use it.

The Tolerance Question

This is the part most cannabis marketing conveniently skips over, so let's be direct about it.

When you use cannabis for sleep every night, your body adapts. The same dose that helped you drift off in November might feel less effective by February. This is tolerance, and it's a real consideration. Some researchers have found that daily users report more sleep problems than occasional users — and in some studies, more problems than people who don't use cannabis at all.

The implication isn't that you should never use cannabis for sleep. It's that using it thoughtfully — perhaps a few nights a week rather than every night — may preserve its effectiveness longer while letting your body maintain its natural sleep rhythms.

If you've been using cannabis nightly and decide to stop, you should know that withdrawal often includes a few nights of disrupted sleep and vivid dreams. This usually settles within a week or two. The dreams, some people find, are actually interesting after months of not remembering them.

Why Terpenes Matter More Than You Might Think

When people ask what cannabis varietal might help with sleep, they're usually thinking about THC content. But the terpenes— the aromatic compounds that give each varietal its distinctive smell — may matter just as much.

Myrcene is the one to know. It's the most abundant terpene in cannabis, with an earthy, slightly musky character. Research suggests it interacts with GABA receptors in the brain — the same system targeted by prescription sleep medications — promoting relaxation and extending sleep time. Cannabis varietals with more than 0.5% myrcene are often associated with that deep, body-heavy feeling some folks call "couch-lock."

Linalool, the terpene that gives lavender its calming reputation, shows up in some cannabis varietals too. It's been studied for its ability to reduce anxiety, which for many people is the real barrier to falling asleep in the first place.

At our farm, we've bred varietals with these profiles in mind. Living soil cultivation in Vermont's Connecticut River floodplain tends to produce plants with full, developed terpene profiles — something you don't always get from indoor grows under artificial lights. When you can smell a jar and actually identify those different notes, that's the terpenes talking.

A Word About CBN

You may have heard about cannabinol, or CBN, marketed as "the sleepy cannabinoid." The research here is genuinely promising. A 2024 study from the University of Sydney found that CBN increased both non-REM and REM sleep in controlled studies, with effects comparable to the prescription sleep medication zolpidem.

What's interesting about CBN is that it's formed naturally as THC ages. Older cannabis contains more of it, which may explain the folk wisdom that "aged cannabis" feels more sedating. Unlike THC, CBN doesn't appear to cause significant intoxication at typical doses.

A separate double-blind, placebo-controlled trial with 321 participants found that 20mg of CBN reduced nighttime awakenings and overall sleep disturbance. That's solid evidence — the kind that actually holds up.
