Short answer: Delta-8 THC is an intoxicating cannabinoid usually made by chemically converting hemp-derived CBD. It has been sold widely in gas stations, vape shops, and online under the 2018 hemp law. It is not FDA-approved, products are often mislabeled or contaminated, and a 2025 federal law ends its hemp protection on November 12, 2026.
Key takeaways
- What it is: Delta-8 THC is a semi-synthetic cannabinoid (hemp-derived) and not a federally controlled substance.
- Medical use: None approved.
- Timing: effects start in minutes (inhaled); 30 minutes to 2 hours (edibles) and last 2 to 4 hours (inhaled); 4 to 8 hours (edibles).
- Most dangerous mix: Alcohol, which can cause stronger impairment and dizziness.
- Naloxone: it does not reverse this drug, but give it whenever opioids could be involved.
- Dependence risk: Moderate.
- Legal route: delta-8 THC is not federally scheduled as of October 2026, but state bans, FDA restrictions, and pending federal action can apply; check current status.
What is delta-8 THC?
Delta-8 THC occurs naturally in cannabis only in trace amounts. Products sold in stores are made by chemically converting CBD, sometimes using harsh chemicals, in largely unregulated facilities.
Delta-8 causes a high similar to cannabis: relaxation, euphoria, altered perception, increased appetite, dry mouth, red eyes, and impaired coordination and reaction time. Many people find it somewhat milder than delta-9 THC.

Too much delta-8 can cause extreme sleepiness, confusion, vomiting, a racing heart, panic, and, in children, slowed breathing and coma. Call Poison Help or 911 if a child eats a THC product.
If someone is having a dangerous reaction
- Call 911 for a seizure, chest pain, a very high temperature, trouble breathing, unresponsiveness, or if the person may harm themselves or others.
- Move them to a quiet, safe place away from roads, water, heights, and crowds. Stay with them and speak calmly.
