THC or Tetrahydrocannabinol is the main psychoactive substance found in the Cannabis plant.
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 ethanol or hexane.
Some studies indicate a variety of negative effects associated with constant, long-term use, including short-term memory loss.
