Marijuana (THC)
What is it?
Marijuana and hash, an often associated drug, are both considered mind-altering drugs.[2] These drugs affect mood, perception, and behavior. [2] Both marijuana and hash contain a chemical called tetrahydrocannabinol (THC) and come from the plant Cannabis Sativa. [2][3] When compared to hash, marijuana has a lower concentration of THC.[2] Marijuana is the dried plant material whereas hash comes from the plants’ trichomes, or the sticky hairs on the plant.[2][3]
THC’s chemical structure is similar to brain chemicals, such as anandamide, which act on cannabinoid receptors.[3] These receptors influence pleasure, memory, thinking, concentration, sensory and time perception, and coordination.[3] When there is an increase of THC in the system, these receptors are overloaded which is why there is a “high”.[3] However, this high imbalances the system, which is the reason for the symptoms listed below.[3]
When young people use THC containing compounds, it can affect brain development so that the short term effects become permanent.[3] Studies have shown that adolescence usage decreases IQ by an average of 8 points, and many abilities that were lost didn’t return, even when they quit.[3]
