Δ9-THC cannabis: “high” effect, effect, flowers – delta-9-tetrahydrocannabinol
Δ9-THC, also known as delta-9-tetrahydrocannabinol, is the best-known cannabinoid of the cannabis plant and is responsible for the typical psychoactive effects (it is also sold in pure form in pharmacies like
Δ9-THC: What exactly is that?

Cannabinoid Übersicht

Cannabinoid Übersicht
Δ9-THC is the most common form of THC and the best-known psychoactive component of cannabis flowers. It binds directly to receptors in the brain and influences perception, mood and the sensation of pain. Due to these properties, Δ9-THC is not only used for recreational consumption, but is also used specifically in medicine – for example for chronic pain, nausea and loss of appetite.
3 facts about Δ9-THC:
- Δ9-THC stands for delta-9-tetrahydrocannabinol
- Main active ingredient of the cannabis plant
- Psychoactive effect and medical use
Δ9-THC in medicine: dronabinol
In medical therapy, Δ9-THC is often used in the form of
Dronabinol is not “artificial THC”, but standardized, pure Δ9-THC in pharmaceutical quality.
Dronabinol is usually produced in pharmacies as drops, capsules or oily solutions. Due to the exact amount of active ingredient, it is particularly suitable for patients for whom a precise dosage and consistent effect are paramount. Compared to cannabis flowers, however, it lacks the entourage effect of other cannabinoids and terpenes.
How Δ9-THC works in the body
Δ9-THC binds to CB1 receptors in the brain and CB2 receptors in the immune system. As a result, it influences the endocannabinoid system and alters processes such as pain perception, mood, appetite and memory. The effect depends on the dose, strain and form of consumption and can be relaxing, mood-enhancing or even activating.
- Has a strong psychoactive effect

Δ9-THC compared to Δ8-THC, Δ10-THC and CBD

Cannabinoide Übersicht
Cannabinoids such as Δ8-THC, Δ10-THC, CBD and Δ9-THC differ significantly in their effects.
- While Δ9-THC has the strongest psychoactive effect,
- Δ8-THC is considered milder and more relaxing.
- Δ10-THC is often associated with more energy and focus.
CBD, on the other hand, does not have an intoxicating effect, but rather a calming and anti-inflammatory one.
Δ9-THC is the “classic” THC form – strong, versatile and the basis for most medical THC products.
Remember Δ9-THC and its special features:
- Δ9-THC is the most common and best-known form of THC
- Strongly psychoactive and versatile
- Has great medical potential
Δ9-THC and the entourage effect
Δ9-THC plays a central role in the “entourage effect“. As described, together with CBD, Δ8-THC, Δ10-THC and other cannabinoids, the effects reinforce or complement each other. For medical applications, flowers and extracts are therefore specifically selected to achieve the optimum balance of THC and other active ingredients.
This makes Δ9-THC the most important cannabinoid for psychoactive effects and a central substance in medical cannabis research.
