Tetrahydrocannabinol 

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!

delta-9 tetrahydrocannabinol 

Or 'THC' for short. This is the chemical in marijuana that gets you HIGH.

When smoking medical marijuana, the amount of the cannabanoid delta-9 tetrahydrocannabinol (THC) in it will determine the psychoactive effect or head "high" the patient experiences. Cannabidiol or 'CBD' is the other cannabanoid found in marijuana and interacts with THC. CBD is known for providing positive effects to the body without the psychoactive (heady) effects.
