Start Low, Go Slow: A Complete Guide to Cannabis Dosing
Learn how to dose cannabis safely. Beginner dosing charts, edibles timing, tolerance breaks, and microdosing explained. DC dispensary guide.
Why Dosing Matters More Than Anything Else
The most common reason people have a negative cannabis experience — anxiety, paranoia, dizziness, or feeling overwhelmed — is not the strain they chose or where they bought it. It is dosing. Consuming too much, too fast, before understanding your individual response is the root cause of nearly every uncomfortable cannabis experience.
The good news: dosing is entirely within your control, and the principle is simple. Start low. Go slow. This guide gives you the framework to apply that principle across every consumption method.
Understanding Cannabis Potency
Before discussing doses, it helps to understand what you are measuring.
THC (Tetrahydrocannabinol) is the primary psychoactive compound in cannabis. It is measured as a percentage of total weight in flower, or in milligrams (mg) in edibles, tinctures, and capsules.
CBD (Cannabidiol) is non-intoxicating and may modulate the effects of THC — higher CBD ratios are generally associated with milder, more manageable experiences.
| Product Type | How Potency Is Measured | Typical Range |
|---|---|---|
| Flower | % THC by weight | 15–30% THC |
| Edibles | mg THC per serving | 2.5–100mg per piece |
| Tinctures | mg THC per mL | 5–50mg per mL |
| Vape cartridges | % THC | 60–90% THC |
| Concentrates | % THC | 70–95% THC |
Dosing by Consumption Method
Flower (Smoking or Vaporizing)
Onset: 2–10 minutes
Peak: 30–60 minutes
Duration: 2–4 hours
Flower is the most controllable consumption method because effects are felt quickly, allowing you to titrate (adjust) your dose in real time.
Beginner approach:
- Take one small inhalation
- Wait 10–15 minutes
- Assess how you feel
- Take a second inhalation only if you want more effect
Intermediate/experienced:
- 2–3 inhalations is a typical session for most consumers
- Higher-tolerance users may consume more, but tolerance escalates quickly with frequent use
Edibles
Onset: 30 minutes – 2 hours (highly variable)
Peak: 2–4 hours after onset
Duration: 4–8 hours
Edibles are the most common source of overconsumption. The delayed onset leads many people to take more before the first dose has taken effect. The result — often called "greening out" — is an intensely uncomfortable experience that, while not medically dangerous, can be deeply unpleasant.
Beginner edible doses:
| Experience Level | Starting Dose | Wait Time Before Redosing |
|---|---|---|
| First time | 2.5 mg THC | 2 hours minimum |
| Some experience | 5 mg THC | 90 minutes minimum |
| Regular consumer | 10 mg THC | 60 minutes minimum |
| High tolerance | 20–50 mg THC | 45 minutes minimum |
The golden rule of edibles: If you do not feel anything after 90 minutes, take half your original dose — not a full second dose. Edible metabolism varies dramatically based on body weight, metabolism, whether you have eaten, and individual endocannabinoid system sensitivity.
Tinctures
Onset (sublingual): 15–45 minutes
Duration: 4–6 hours
Tinctures taken under the tongue (sublingually) absorb faster than swallowed edibles. Start with 2.5–5 mg and wait 45 minutes before assessing.
Vape Cartridges
Onset: 2–5 minutes
Duration: 2–3 hours
Vape cartridges are highly concentrated (often 70–90% THC). A single 3-second draw delivers a significant dose. Treat each draw as a single unit and wait 10 minutes between draws.
Concentrates (Dabs, Wax, Shatter)
Concentrates are not recommended for beginners. They deliver extremely high doses of THC very rapidly. Experienced consumers who use concentrates should still apply the start-low principle when trying a new product.
Microdosing
Microdosing refers to consuming sub-perceptual doses of cannabis — amounts small enough that you do not feel intoxicated, but may experience subtle benefits like reduced anxiety, improved focus, or mild pain relief.
Typical microdose range: 1–5 mg THC
Microdosing is particularly popular among:
- Medical patients who need to function normally during the day
- People with anxiety who find full doses too intense
- Consumers building tolerance resets
- First-time users wanting to explore cannabis cautiously
A common microdosing protocol is 2.5 mg THC in the morning and/or afternoon, taken consistently for several weeks to assess cumulative effects.
Tolerance and Tolerance Breaks
Regular cannabis use leads to tolerance — the endocannabinoid system downregulates CB1 receptors in response to consistent THC exposure. This means the same dose produces progressively weaker effects over time.
Signs you have developed significant tolerance:
- Needing significantly more product to feel the same effects
- Feeling little to no effect from doses that previously worked
- Using cannabis primarily to feel "normal" rather than for specific benefits
Tolerance break (T-break) guidelines:
| Break Duration | Expected Tolerance Reset |
|---|---|
| 2–3 days | Partial reset |
| 1 week | Moderate reset |
| 2–4 weeks | Substantial reset |
| 30+ days | Near-complete reset for most users |
After a tolerance break, restart at your original beginner doses — your sensitivity will be significantly higher.
What to Do If You Consume Too Much
If you or someone you are with has consumed too much cannabis:
- Stay calm — cannabis overconsumption is not medically dangerous for healthy adults, though it can feel very uncomfortable
- Find a safe, comfortable environment — sit or lie down somewhere quiet
- Stay hydrated — drink water (not alcohol)
- Black pepper — some users report that smelling or chewing a few black peppercorns (which contain caryophyllene and pinene) reduces anxiety; the evidence is anecdotal but harmless
- CBD — if available, CBD may help moderate THC's psychoactive effects
- Time — effects will pass; most acute discomfort resolves within 1–3 hours
- Seek medical attention if symptoms are severe, the person has a heart condition, or you are concerned about their wellbeing
A Note on Individual Variation
Cannabis affects people very differently based on genetics, body composition, metabolic rate, prior experience, mental state, and the specific product consumed. There is no universal "correct" dose. The framework above gives you a starting point — your personal optimal dose requires experimentation, patience, and honest self-assessment.
