Drug warfare (in more ways than one)

I don't know if it has been done before, but do you guys think it would be beneficial to compile a list of possible drugs (prescription and non) that can, have, and will be used to control and enslave the population, or change policy? I've been reading quite a bit lately about the Opium Wars and how opium was used by the British Empire to control China by increasing China's dependence on British-controlled India.

So we have illegal drugs:

Heroin/opium (India, Afghanistan, etc.)
Cocaine/crack (South America, etc.)
Marijuana (Mexico, Central and South America, etc.)
Meth (USA)
Hallucinogens - LSD, PCP, Shrooms, etc. (?)
Ecstasy

So we know why most of these drugs have been made illegal, the "War on Drugs", essentially an excuse to track and incarcerate the lower and middle class, gives a valid excuse to increase the size of the police state, and apparently it's working.

Now how about prescription drugs:

Opiates - Morphine/codeine/etc. (Again, relying on countries like India and Afghanistan, though these drugs are essential for pain control, but are highly addictive)
Benzodiazepines - Valium, Xanax, Klonipin, Ativian, etc. (used as sedatives, tranquilizers, hypnotic, psychoactive properties, makes people more submissive, less likely to get agitated, these drugs are being practically given away)
Antidepressants - (Many of these contain sodium fluoride)
Stimulants - Amphetamines/MDMA, tons of other drugs (Given to SS soldiers on several occasions to keep them going, regardless of terrible consequences to their bodies).

I know I'm probably missing some since I'm not a doctor, pharmacist, or drug user. I can't help but think that with the vast amounts of drugs being peddled by doctors and drug dealers alike, that some of them could have been the product of social engineering. I wonder how many of these drugs have been created or utilized for control purposes. I wonder how many of our elected officials use these drugs. So if you know anything or have any stories, add it here.
