LSDs inventor Albert Hofmann called it "medicine for the soul." The
Beatles wrote songs about it. Secret military mind control experiments
exploited its hallucinogenic powers. Outlawed in 1966, LSD became a
street drug and developed a reputation as the dangerous toy of the
counterculture, capable of inspiring either moments of genius, or a
descent into madness. Now science is taking a fresh look at LSD,
including the first human trials in over 35 years. Using enhanced brain
imaging, non-hallucinogenic versions of the drug and information from
an underground network of test subjects who suffer from an agonizing
condition for which there is no cure, researchers are finding that this
"trippy" drug could become the pharmaceutical of the future. Can it
enhance our brain power, expand our creativity and cure disease? To
find out, Explorer puts LSD under the microscope.
