Quick Hits
What kind of high is WSU?
A pure indica (100%) reported as relaxed, hungry and creative. Picked for sleep & bedtime and stress relief at night. The profile features pine flavor, earthy pine aroma and myrcene as the lead terpene.
Terpenes help give cannabis its aroma. Compare citrus, pine and earthy notes to find what appeals to you. The profile offers clues, not a guaranteed high.
Terpene percentages belong to the jar, not the strain. They move with harvest timing, drying, cure and shelf age — the lighter ones literally evaporate. What holds steady is which terpenes lead, so that is what we rank.

There’s more to a strain than THC%.
THC percentage is a property of the product in your hand, not of the strain. It shifts with the batch, the grower, the harvest, and how the flower was cured and stored — the same strain can test several points apart from two different jars.
Treat the ranges below as market context for what to expect on a shelf — then read the actual label on the product you are buying, and use the terpene profile to judge how it will feel.

Professor High interprets the pattern
The effects hit like stepping into a warm bath after a brutal workout—immediate and all-encompassing. Within minutes, there's this fascinating duality where my mind feels lighter and more content, almost euphoric, while simultaneously my body begins this delicious descent into complete physical surrender. The Myrcene dominance isn't just theoretical—I can literally feel those sedative terpenes doing their work, each muscle group releasing tension in waves. What's particularly interesting is how the Pinene creates these brief moments of mental clarity and focus before the deeper indica effects take full command. The appetite stimulation is real—suddenly everything in my kitchen seems like a five-star meal. As the experience deepens, there's this profound sense of being completely present in my body while simultaneously feeling weightless, like I'm simultaneously grounded and floating. The pain relief is remarkable—discomfort I'd been carrying just... evaporates. This is textbook indica medicine: therapeutic, powerful, and wonderfully sedating. Perfect for when you need nature's reset button pressed firmly and without hesitation.

The helpful detail
Introducing WSU: A Pure Indica Powerhouse
WSU, also known as Washington State University or WASU, stands as a testament to the therapeutic potential of pure indica genetics. This 100% indica strain descended from the legendary Chemo lineage (specifically UBC Chemo) has carved out a reputation as a potent medical strain designed for serious relief. Bred in Washington during the early 2010s, WSU represents a deliberate effort to create a strain that delivers maximum sedative and analgesic properties. With THC levels ranging from 6% to 25% depending on the phenotype and cultivation methods, this strain offers options for both novice patients seeking gentle relief and experienced users requiring heavy-duty therapeutic effects. The strain earned its place in cannabis culture not through flashy marketing, but through consistent performance in addressing chronic pain, insomnia, and appetite loss.
🧬 Genetic Heritage & Lineage
WSU's genetic story begins with Chemo, one of the most respected medical cannabis strains in history. The UBC Chemo parent strain was originally developed at the University of British Columbia in the 1970s specifically to help cancer patients undergoing chemotherapy manage nausea and pain. By selecting this legendary genetic foundation, WSU's Washington-based breeders ensured the strain would carry forward Chemo's renowned therapeutic qualities while adapting it for modern cultivation standards. The strain emerged in 2013 during the early days of Washington's legal cannabis market, representing a bridge between old-school medical genetics and contemporary craft cannabis. This pure indica composition means you're getting unadulterated sedative and body-focused effects without any sativa stimulation—exactly what patients seeking deep relaxation and pain relief desire.
👃 Terpene Profile & Aromatics
WSU's aromatic complexity comes from an impressive terpene blend dominated by Myrcene at 50%—an unusually high concentration that explains the strain's powerful sedative effects. Myrcene, known for its musky, earthy character, works synergistically with the cannabinoids to enhance the "couch-lock" sensation and promote deep physical relaxation. Pinene follows at 43%, adding crisp pine notes that cut through the earthiness while potentially improving alertness and memory retention—an interesting counterbalance to the heavy body effects. Caryophyllene at 29% contributes spicy, peppery undertones while uniquely binding to CB2 receptors to provide anti-inflammatory benefits. Limonene at 28% rounds out the major terpenes with bright citrus notes and mood-elevating properties. Minor players include Carene (0.63%) and Ocimene (0.12%), which add subtle complexity with sweet, herbal whispers.
The overall aroma profile opens with dominant pine forests—fresh, resinous, and clean. As you break apart the buds, berry sweetness emerges alongside earthy undertones and unexpected grape notes. Some phenotypes exhibit a distinctive chemical or diesel-like sharpness that hints at the strain's medicinal potency. Woody and sweet base notes provide a comforting foundation to this complex aromatic tapestry.
👅 Flavor Experience
WSU's flavor journey mirrors its aromatic complexity but reveals itself in layers. The initial inhale delivers crisp pine that coats your palate, immediately followed by berry sweetness and grape richness. Mid-palate, you'll detect citrus brightness that adds dimension, while diesel and chemical notes remind you of this strain's serious medicinal pedigree. The exhale brings earthy groundedness with lingering woody and sweet notes that create a surprisingly pleasant aftertaste. Some users note subtle sage and menthol cooling sensations that add refreshing complexity.
🎯 Effects & Experience
WSU delivers exactly what pure indica genetics promise: profound relaxation that begins within minutes of consumption. You'll first notice a gentle wave of euphoria and happiness washing over your mind, creating a contented mental state before the heavier body effects arrive. Within 10-15 minutes, the experience transitions to full-body sedation characterized by deep calmness and the classic indica "melt." Your muscles release tension you didn't know you were holding, and physical discomfort begins to fade into the background.
The hungry effects—commonly called "the munchies"—arrive reliably with WSU, making this strain particularly valuable for patients dealing with appetite loss. As the experience progresses, sleepiness becomes increasingly prominent, making this definitively a nighttime strain. The effects typically last 2-4 hours, with peak intensity occurring 30-60 minutes after consumption. Some users report surprising moments of creativity and uplifted mood during the initial onset, though these mental effects eventually give way to the dominant sedative qualities.
💚 Medical & Therapeutic Potential
WSU shines brightest in therapeutic applications. The strain may help significantly with chronic pain management, leveraging both its high THC content and pain-relieving terpenes like Caryophyllene. Patients report relief from conditions including arthritis, muscle spasms, cramps, and general inflammation. The strain's sedative properties make it potentially valuable for insomnia and other sleep disorders—many users report WSU helps them achieve deeper, more restorative sleep.
The appetite-stimulating effects may benefit patients dealing with nausea, anorexia, or appetite loss from medical treatments. Mental health applications include potential support for stress relief, depression management, and even ADHD symptoms, though the heavy sedation means this isn't a daytime solution. As with all medical cannabis, individual results vary, and consultation with healthcare providers is recommended.
👁️ Visual Characteristics
WSU buds present as dense, resinous nuggets with deep forest green coloration and purple undertones that become more pronounced in properly cured flowers. Fiery orange to rust-colored pistils weave throughout the bud structure, creating striking visual contrast. The crystal density ranges from high to very high depending on the phenotype, with amber and cloudy trichomes creating a frosty appearance that signals potency. The bud structure is characteristically indica—tight, compact, and heavy for their size.
⚠️ Consumer Considerations
WSU is best suited for evening and nighttime use, ideal for unwinding after a long day or preparing for sleep. Begin with low doses if you're new to cannabis or have low THC tolerance—even the 6% THC phenotypes deliver notable effects. Common side effects include dry mouth and dry eyes, both easily managed with hydration and eye drops. The strain's availability is relatively common through dispensaries in legal markets, often sold under its full "Washington State University" name or the WASU abbreviation.
