Could LSD be the next drug in your doctorâ€™s arsenal? New experiments have a few researchers believing that this trippy drug could become a pharmaceutical of the future.

Now science is taking a fresh look into this psychedelic world, including the first human LSD trials in more than 35 years. LSDâ€™s inventor Albert Hofmann called it medicine for the soul. The Beatles wrote songs about it. Secret military mind control experiments exploited its hallucinogenic powers.
