In the Us Cocaine was lang time used as a wonderdrug, for boosting energy, mindstates, and such. Before people becaming crazy after longer-term use. Sigmund Freud wrote his dream theories while he was using several grams a day. He LOVED it. Untill he tried to quit, and noticed he could not at first. Then he became strongly against it.
No wonder he got vivid dreams LOL.
A quote: by my favorite philosofer Carl Gustav Jung
Every form of addiction is bad. No matter wether the narcotic is be alcohol, morphine or idealism.
