Tetrahydrocannabinol (THC), is the main psychoactive ingredient in the Cannabis Sativa plant that gets a user 'High'.
It's scientific name is Δ9-tetrahydrocannabinol (delta-9-tetrahydrocannabinol), Δ¹-tetrahydrocannabinol (using an older numbering scheme), or dronabinol, is the main psychoactive substance found in the Cannabis plant. It was isolated by Raphael Mechoulam and Yechiel Gaoni from the Weizmann Institute in Rehovot, Israel in 1964. In pure form it is a glassy solid when cold and becomes viscous and sticky if warmed. THC has a very low solubility in water, but a good solubility in most organic solvents such as pure ethanol or hexane.
Scientist: Man, that pot had a high tetrahydrocannabinol potency!
A gland developed when a person has ingested a significant amount of Tetrahydrocannabinol (THC, found in the Cannabis Sativa plant). Usually ingested by smoking. The Weedicle gland is a gland that has evolved from excessive amounts of THC. This gland allows the person to get 'High' from THC at will, without the need of Cannabis.
