I bought this book right when it came out and am surprised it isn't sourced more around the internet. It goes over the movements destroyed by CIA, and their murderous operations around the world. The Subtitle of the book is : "The CIA's Murderous Targeting of SDS, Panthers, Hendrix, Lennon, Cobain, Tupac and Other Activists"
His book will be my primary source for this article.
History shows us that some of the first drugs/poison to be discovered as tools was as early as 3400B.C. in Sumeria, poppy/opium.
McCoy conducted "more than 250 interviews, some of them with past and present officials of the CIA He said that top-level South Vietnamese officials, including President Nguyen Van Thieu and Premier Tran Van Khiem, were specifically involved." 
From sourcing another one of McCoy's books Potash finds "that from 1953 to 1963, the CIA received funding of $25 million for mind control research."
If you notice the time periods, this is right before the Bretton Woods breakdown, the Hippie movement, and the rise of LSD. LSD is particularly interesting as Potash argues that CIA dealing of street acid diminished the affects of the benevolent groups distributing as a meditative and third eye opening experience.
In His Chapter, "CIA Acid Fests Counter Protests", are some interesting things.
"Frank Zappa and David Crosby by the mid-1960s were some of the musicians who held huge drug and sex-filled parties in their Laurel County Mansions." Some who attended were Charles Manson, Roman Polanksi, and others. 
LSD, Heroin, and Cocaine were associated with high profile stars to attract youth and aspiring individuals to take them. The Grateful Dead used the powerful American biker gang, Hell's Angel's... to enforce security and stop the nonsense at their shows after things got out of hand with Heroin and people started to die.
Nowadays at shows instead of getting a slap on the wrist from the Hell's angels you have county sheriff's stealing drugs from everyone creating division between government and fans.
An interesting point made by Potash is in February 1971, Stephen Gaskin, a government employee at San Francisco State University, traveled with 25 Colorfully painted Buses, 35-50 vans and campers, who had no recognizable jobs, to Churches across america for 4 months across 42 states. Who funded that?
In 1970, Ronald Stark, a person who showed up to the Brotherhood of Eternal Love with 1.5 kilos of acid, acknowledged he worked for the CIA. 
Che Guevara, in 1950s he took a homemade motorcycle around Latin America and witnessed some evil by the United Fruit Company which inspired his revolution in Cuba.
Secretary of State John Foster Dulles was a stockholder and attorney for the United Fruit Company, while his brother Allen Dulles, headed the CIA in the 1950s.
The CIA's main goal is to keep systems of slavery and wealth transfer in place and disrupt massive World Awakening towards scientific reasoning and advancement.
"The CIA and U.S. Military prepared to launch a Coup against Allende's government on September 11, 1973."
"In the days following the coup General Augusto Pinochet and his military henchmen arrested 13,500 civilians in Santiago and traveled the country with death squads."
By 2006, Chile put Paul Schafer, a World War II Nazi doctor who founded an enclave on trial and convicted him of working with Pinochet's military and intelligence services to kidnap and torture 'leftists'.
After the Pinochet operation and the takeover of Chile, the CIA had many assets, including former Nazis (Operation Paperclip) to bring another drug to the table across the world... Cocaine.
I also noticed Steve Liesman, an intelligence connected TV slut at their anniversary in Chicago, good one Grateful Dead!
LOL look what I did during their Anniversary - That was me! Sometimes the light's shining on me... protecting the fans from a bullshit festival I was hired to do their website, and was never paid.
