A Lipsett Amphitheater full of eager attendees listened intently, some of them perhaps hoping to hear validating evidence of the merits of marijuana. But the jury’s still out: while marijuana has some therapeutic potential, more research is needed. What we do know, said Dr. Marilyn Huestis, chief of the chemistry and drug metabolism section at the National Institute on Drug Abuse, is that the harmful effects of marijuana last longer than you may realize. The primary psychoactive chemical in marijuana, Δ-9-tetrahydrocannabinol (THC), is stored in the body after chronic, frequent marijuana use.

Diagrams that use words, color and pictures to organize information can help people be more creative and plan more efficiently, said author Jamie Nast at a Deputy Director for Management Seminar in Masur Auditorium recently.

The areas of dominance in the left hemisphere include: logic, listing, linearity, words, numbers, analysis and sequence. The areas of dominance in the right hemisphere include: color, rhythm, imagination, day dreaming, spatial and gestalt. Idea mapping leverages both sides of the brain. The combination of left plus right increases creativity.
