[top]Introduction to Tetrahydrocannabinol

[top]Using Tetrahydrocannabinol

THC is generally used as cannabis or some cannabis-derived preparation (hashish, space cakes, etc). THC, in its synthetic form (Dronabinol) to be used orally, is also available in some countries.

[top]Ways of Administration

THC, when derived from a natural source can be smoked, vaporized or ingested as cannabis and related preparations.

Synthetic THC is available for oral administration. In some studies, THC is administered intravenously.

[top]Effects of Tetrahydrocannabinol

The effects of THC are similar to those of cannabis, although some differences exist.

[top]Objective effects

- Reduced intraocular pressure

[top]Subjective effects

- Increased appetite

[top]Combinations with Tetrahydrocannabinol

THC is usually combined to the other cannabinoids found in cannabis. The combinations are the same as those of cannabis.

[top]Different Uses for Tetrahydrocannabinol


THC, as Dronabinol, is used to increase appetite of aids patients.

[top]Pharmacology of Tetrahydrocannabinol

LD50 (mg/kg) (sesame oil emulsion of ∆9-THC)[1] :
Male rat : 800 orally, 672 intraperitoneally, 35.5 intravenously

LD50 (mg/kg) (∆8-THC)[1]:
Mice : 27.5 intravenously

[top]Chemistry of Tetrahydrocannabinol

From a chemical point of view, THC consist of seven isomers, depending on the position of the insaturation on the "upper" ring consisting of the carbons 6a-7-8-9-10-10a.

Apart from the aforementionned positionnal isomers, 4 stereoisomers exists depending on the absolute configuration of the 6a and 10a carbons.
