CS Cannabinoid index · Intoxicating
Delta-8-THC (delta-8-tetrahydrocannabinol) is an isomer of regular delta-9-THC. It is intoxicating but generally milder, and it occurs naturally only in trace amounts, so most delta-8 products are made by chemically converting CBD. The FDA has issued consumer warnings about delta-8 products over safety and mislabelling; it is not an approved medicine.
How it is made, and infusion
Unlike THC or CBD, delta-8 is not something you meaningfully decarb from flower; it is a manufacturing product.

What the published literature examined
Delta-8-THC’s basic pharmacology, as a CB1-active isomer of delta-9-THC with weaker intoxicating potency, comes from older studies. Most recent attention is not clinical but regulatory: the FDA and poison-control networks have documented adverse events tied to unregulated delta-8 products, and analyses have found that commercial products often do not match their labels and can carry synthesis by-products.
What is established, and what is not
Established: that delta-8-THC is intoxicating, an isomer of delta-9, and that most commercial delta-8 is synthesised from CBD, with real product-quality and safety concerns flagged by regulators. Not established: any approved therapeutic use, and the safety of unregulated products, which vary batch to batch.

Frequently asked questions
Is delta-8 the same as regular THC?
No, but it is close: delta-8 is an isomer of delta-9-THC, with the double bond in a different position. It is intoxicating but usually milder.
Is delta-8 natural?
Only in trace amounts. Most delta-8 products are made by converting CBD in a lab, which is why product quality and purity vary.
Has the FDA warned about delta-8?
Yes. The FDA has issued consumer warnings citing adverse-event reports and inconsistent, sometimes contaminated products. It is not an approved medicine.
