THCa vs Weed 2025:
Hemp Labels and Shipping Rules
Same plant family. Different rulebooks. Read labels, understand shipping basics, and shop StreetStem lab-tested hemp with confidence.
You want lab-tested hemp that actually checks out. Here’s the 2025 breakdown on THCa vs weed so you can read hemp labels, understand shipping rules, and shop StreetStem lab-tested hemp with confidence.
The Quick Truth
- Total THC is the anchor: many programs use Δ9 + (0.877 × THCa) to decide hemp compliance.
- Court support: on Jan 7, 2025 a federal appeals court upheld Virginia’s total-THC framework.
- Shipping reality: USPS allows certain hemp at or below 0.3% THC in domestic mail if laws are met and records are kept; the USPS ENDS rule makes consumer vape mail non-mailable. Private carriers (UPS, FedEx) have their own restrictions.
