Cannabis Flower
The original form. Still the most misunderstood. Here's what's actually in your bud, how it works, and what matters when you're choosing and consuming it.
Pharmacology
How cannabis actually works
Cannabis flower contains over 100 cannabinoids, but two do most of the heavy lifting: THC (delta-9-tetrahydrocannabinol) and CBD (cannabidiol). THC is the primary psychoactive compound — it binds to CB1 receptors in the brain and central nervous system, producing the characteristic high. CBD is non-intoxicating and modulates how THC behaves.
The endocannabinoid system (ECS) is a signaling network that exists in all mammals. It regulates mood, memory, appetite, pain, and sleep. Cannabis works because THC closely resembles anandamide, the body's naturally occurring endocannabinoid. When THC binds CB1 receptors, it produces effects that your brain's own chemistry can't replicate at anywhere near that intensity.
CB2 receptors are found primarily in immune tissue and the peripheral nervous system. CBD and some other cannabinoids act here, which is why cannabis has documented anti-inflammatory properties that don't require getting high.
The entourage effect
THC doesn't act alone. Terpenes, CBD, CBG, CBN, and dozens of other minor cannabinoids all interact with each other and with your endocannabinoid system simultaneously. The combined effect is meaningfully different from THC in isolation — which is one reason high-potency distillate feels so different from good whole flower.
Potency
THC percentages and what they actually mean
Dispensary flower typically ranges from 15% to 30%+ THC. That number is the percentage of THC by dry weight. A gram of 20% flower contains roughly 200mg of THC before any accounting for combustion or vaporization losses.
But that number is less meaningful than the industry pretends. Consumers routinely rate lower-THC flower as more enjoyable than high-THC equivalents in blind testing. Why? Terpenes, cannabinoid ratios, and grow quality matter more than the headline THC number. Chasing percentage is one of the most reliable ways to have a bad time.
What the label doesn't tell you
Lab testing in most states has serious accuracy problems. Studies have found that cannabis labels frequently overstate THC content, sometimes by 15–30%. Some labs compete for business by delivering favorable numbers. The percentage on your jar is a starting point, not a guarantee.
CBD in dispensary flower
Modern dispensary cannabis has been selectively bred for THC dominance over decades. CBD has largely been bred out — most dispensary flower contains less than 1% CBD, sometimes closer to 0.1%. If you want meaningful CBD content, you're looking at hemp flower or specific high-CBD cultivars, not the average dispensary shelf.
Cultivars
The indica/sativa problem
The cannabis industry still sells flower as "indica" (relaxing, body high) or "sativa" (energizing, heady). This framework is not scientifically accurate. Modern cannabis genetics are so extensively hybridized that the terms have essentially no predictive value for effect.
Botanically, indica and sativa describe plant morphology — how the plant looks and grows. A short, bushy indica-phenotype plant and a tall, narrow sativa-phenotype plant can produce nearly identical effects when the cannabinoid and terpene profiles are similar.
The better question is: what are the terpenes and cannabinoid ratios in this specific batch? That's where the actual effect prediction lives. A myrcene-dominant flower will feel different from a limonene-dominant one regardless of what the label calls it.
What actually predicts effect
Terpene profile + cannabinoid ratios + your individual endocannabinoid system + set and setting. The strain name is marketing. Ask your budtender for the lab panel, not the category.
Terpenes
The compounds that actually shape your experience
Terpenes are aromatic compounds found throughout the plant kingdom. Cannabis produces over 150 of them, and they interact with cannabinoids to shape the character of the high. This is the entourage effect in practice.
Consumption
How you consume it changes everything
Temperature matters in vaporization
Lower temps (160–180°C) favor terpene expression and a more clear-headed, functional high. Higher temps (185–210°C) extract more THC and CBN, producing heavier sedation. Start low. The Volcano and most quality vaporizers let you dial this in. Tim's personal protocol: 160°C preheat → 170°C → 180°C → 187°C → 195°C across a session.
Dosing
How much to use
Dosing cannabis flower is less precise than dosing edibles because bioavailability varies with technique, lung capacity, and individual metabolism. That said, THC content gives you a starting point.
| Experience level | Suggested approach | What to expect |
|---|---|---|
| First time / no tolerance | One or two puffs from flower under 18% THC. Wait 15 minutes before more. | Mild euphoria, altered perception, possible anxiety if overdone |
| Occasional user | A bowl or half a joint of mid-potency flower. Know your pace. | Reliable high, good terpene expression, manageable duration |
| Regular user | Tolerance has shifted your baseline. Consider tolerance breaks to reset sensitivity. | Diminishing euphoria, increased reliance for baseline function |
| High tolerance | Flower may feel ineffective. Consider a T-break before escalating to extracts. | CB1 downregulation is real — more isn't always the answer |
CB1 downregulation
Chronic heavy use causes CB1 receptor downregulation — your brain literally reduces the number of receptors in response to constant activation. This is why daily heavy users report feeling less effect for more product over time. It's also why tolerance breaks work: receptor density recovers within weeks of abstinence. This isn't addiction in the classical sense, but it's real physiology worth understanding.
Harm Reduction
What actually matters for safety
Cannabis has no known lethal dose and extremely low acute toxicity. The risks are real but often mischaracterized. Here's an honest accounting.
Respiratory health
Combustion — burning anything and inhaling it — carries respiratory risk. Cannabis smoke contains many of the same irritants as tobacco smoke, minus nicotine. Chronic heavy smoking is associated with increased bronchitis symptoms. Switching to vaporization significantly reduces this exposure. If you smoke regularly and value your lung health, it's worth the switch.
Mental health and cannabis
The cannabis-psychosis link is real but often overstated in public discourse. High-potency THC, especially at high doses in people with personal or family history of psychotic disorders, carries elevated risk. This is not a theoretical concern. It's also not a reason for blanket prohibition — it's a reason for honest risk stratification. Know your history, start low, avoid concentrates if you're in a vulnerable period.
Adolescent use
The developing brain is meaningfully more vulnerable to cannabis's effects on memory and cognitive development. The evidence on adolescent cannabis use and long-term outcomes is less alarming than prohibitionists claim but more concerning than cannabis advocates tend to acknowledge. This is one place where the honest answer is: the risk is real, and it's higher the younger you start.
Driving
Cannabis impairs reaction time and divided attention. Don't drive stoned. This is not debatable. The impairment is real even when it doesn't feel that way to the user — especially in the first 1–2 hours after consumption.
If you get too high
You're not going to die. Find a quiet, comfortable place. CBD, black pepper (smelled or chewed), and cold water can help. Lie down if you're dizzy. Focus on slow breathing. It will pass — typically within 1–2 hours for flower, longer for edibles. See the Too High Toolkit for more.
The dispensary experience has trained people to optimize for the wrong variable. THC percentage is the number they put on the jar because it's easy to measure and it sells product. But the most interesting cannabis I've had in years has been mid-potency, terpene-rich flower that someone grew with care — nothing on the dispensary shelf competes with it on actual experience.
Buy for terpenes. Find a cultivar where you can actually get the lab panel and look at what's dominant. If your dispensary can't tell you the terpene profile, that's information too.
