Cannetics: CBD Guide & Tools

Duffy By Design

About this app

Cannetics is an independent CBD research publisher. This app puts our free calculators and plain-English guides in one place, with no storefront and nothing to buy.

WHAT'S INSIDE

Five free calculators:
- Dosage calculator: work out a sensible starting amount from your weight and goal
- Half-life calculator: understand how long CBD stays in your system
- Bioavailability calculator: see how much you actually absorb by method
- Drug-test risk calculator: understand detection windows and the real uncertainty
- Price per milligram calculator: compare value honestly instead of by bottle price

CBD 101 guides:
Nine short reads covering what CBD is, how it differs from THC, dosing, safety, drug interactions, storage, and how to read a lab report. Every guide tells you what the evidence supports and what it does not.

Article library:
Hundreds of evidence-based articles, each grounded in current published research. Search by topic, filter by category.

Product finder quiz:
Answer a few questions about your goal, experience and budget, and get matched to the kind of CBD that fits, with the reasoning shown. About two minutes.

WHAT THIS APP IS NOT

- Not a shop. There are no products to buy, no carts and no checkout.
- No affiliate links anywhere inside the app.
- No THC products, and no Delta 8 or Delta 9.
- Not medical advice.

INDEPENDENCE

Cannetics is not paid by any brand for coverage. Recommendations are not shaped by commission. Our methodology and editorial standards are published on our website.
