A guide for adults 21+, with state laws last reviewed October 28, 2026 by Roy Lloyd.
Clear education, dose-planning tools, documented product picks, and state-by-state THCA law, so you can decide with confidence before you buy.
The guides to read first if you're new to hemp-derived THC, its legal context, or beginner-friendly dosing.
The right THC dose is personal. No chart gives you a number that works for everyone. Here is how to find your own starting point and adjust from there.
THCA still qualifies as federal hemp under the 2018 Farm Bill's delta-9 test until December 11, 2026, then most high-THCA products lose that exemption. November 12 is a separate date for cannabinoids the plant cannot make. State rules already vary.
For beginners, the right THC gummy is the one with the clearest per-piece dosing and the lowest available dose. The most important thing you need to understand is not the brand — it's the delayed onset.
Calculators that set realistic expectations for dose, timing, and potency before you try a product.
| Tool | What it answers | Open |
|---|---|---|
| THC Dosage Calculator | A starting range in milligrams, from your weight, experience, and whether the product is a gummy, tincture, or vape. | |
| Edible Timing Calculator | When a gummy, softgel, or drink may start, peak, and wear off, so you can wait before taking more. | |
| THCA to THC Conversion Calculator | How much THC a listed THCA percentage may become after heating, using the 0.877 factor. | |
| THC vs CBD Comparison Tool | A THC-forward, CBD-forward, or balanced direction, based on how noticeable you want the experience and how sensitive you are to THC. | |
| THC Tolerance Estimator | A rough tolerance band from how often you use THC, a typical serving, and how many days it has been. |
