These drugs can be classified into three groups depending on their mental effect (stimulant, sedative or hallucinogenic).
The term therapeutic dosage is used for medicines and “active” dosage for the “street” drugs.
Each of these three groups is divided into several categories.
Each category is composed of numerous products or active ingredients.
Psychotropic drugs have no foreseeable effect. Stimulant, sedative or hallucinogenic effects of the products are dependant on the dose received and on one’s sensitivity.
They all have unpredictable and dangerous physical and mental effects, which are called “secondary effects” by the manufacturers.
