Sensation-seeking, reward sensitivity and early cannabis use
Sensation seeking, or the tendency to seek out exciting experiences, has been linked to addiction. At the American College of Neuropsychopharmacology annual meeting, Dr. Patricia Conrod of the University of Montreal and Le Centre Hospitalier Universitaire Sainte-Justine, reported sensation seeking is related to reward sensitivity in teens, and that a school-based intervention that targeted sensation seeking delays the onset of cannabis use, and slows the progression from light to heavy cannabis use in teens....
Cannabis increases the noise in your brain
Several studies have demonstrated that the primary active constituent of cannabis, delta-9-tetrahydrocannabinol, induces transient psychosis-like effects in healthy subjects similar to those observed in schizophrenia. However, the mechanisms underlying these effects are not clear. A new study shows that this active ingredient increases random neural activity, termed neural noise, in the brains of healthy human subjects. The findings suggest that increased neural noise may play a role in the psychosis-like effects of cannabis....
