Qualaquin, Quinine sulphate and Quinine medication use and abuse



Type of Spiritual Experience


Number of hallucinations: 581


According to Dr Duke Qunine is :

QUININE : Abortifacient; Allergenic; Amebicide IC50=14.8 ug/ml; Analgesic; Anesthetic; Antibacterial; Antidysenteric; Antifeedant; Antifibrillary; Antihemorrhoidal; Antilumbagic; Antimalarial IC50=0.18 ug/ml; Antineuralgic; Antineuritic; Antipyretic; Antisciatic; Antitrypanosomic; Antiyeast; Apertif; Astringent; Cardiodepressant; Cytotoxic IC50=183 ug/ml; Dermatitigenic; FLavor FEMA 5-83 (-100); MDR-Inhibitor IC50=4-17 uM; Oxytocic; Pesticide; Phototoxic; Protisticide; Spermicide; Stomachic; Trypanocide

We are unable to work out why the resultant drug is thus the subject of abuse unless it is its anaesthetic effects and antineuralgic effects.  Taken as a pill, there is a high likelihood of overdose

It is known that codeine and quinine inter-act and have an hallucinogenic effect

A description of the experience

Qunine is one of the active ingredients in cinchona bark, but not the only one.  Good tonic water, for example, is made from the bark as a whole, whereas the medication sold by pharmaceutial companies is just the chemical.
