• § 35-7-1031(c) — "knowingly or intentionally possess a controlled substance"; explicitly disclaims practitioner authority to prescribe marijuana.
• § 35-7-1031(d) — carrier-weight rule for edibles and other compound products.
• § 35-7-1040 — distribution to a minor 3+ years junior — felony, 20 years / $10,000.
• § 35-7-1049 — civil asset forfeiture procedures; post-2016 30-day probable-cause-hearing requirement.

• § 35-7-1904 — affirmative defense to possession charges for cardholders.

• § 31-5-233(b)(iii)(A) — alcohol per se 0.08% BAC.
• § 31-5-233(b)(iii)(B) — controlled-substance impairment-based standard; no per se THC threshold.
• § 31-5-233(d) — out-of-state medical-cannabis recommendation is not a defense.
