10 most common illegal drugs used around the world – You need to see #1 (With Pictures)

6. LSD (Acid)

As one of the most potent mood-changing chemicals known, little wonder it was the second most sold drug on the Darknet in 2014. The rush of emotions, altered thinking processes, crossing over of sensations where users start to hear colors and see sounds are some of the reasons this drug has been used since the 1940s.

Adverse side effects include temporary confusion, impaired memory and panic attacks. Yet this has remained a popular drug among creative types: LSD has been credited for inspiring hit songs, and even scientific discoveries. Even in Silicon Valley, LSD is used by many as a way to “get in touch with creativity.”

Manufacturing LSD requires time, complex lab equipment and an experienced chemist. Production is highest in illegal laboratories in the West Coast, the Pacific Northwest, and the Midwest of the United States.
