• In other states, THCA remains legally permissible, provided products are lab-tested and compliant (<0.3 % Delta‑9 THC).

• State definitions vary—some focus on total THC, not just Delta‑9, which may restrict THCA-rich hemp.

✅ How to Stay Compliant

1. Check your state laws before purchasing THCA products.

2. Verify third-party COAs confirming Delta‑9 content under 0.3%.

3. Avoid purchasing in banned states, even online.
