Trade, protection of natural populations and reasons for using psychoactive cacti
ŠKRNOVÁ, Veronika
The aim of this work is to process the reasons and volume of trade in psychoactive plants of the Cactaceae family in recent decades for cultivation and altered state of human consciousness in the Czech Republic, to determine the origin, discuss the reasons for endangering natural populations of species since they all appear on list of CITES. Another goal is to analyze the benefits versus risks for modern man to altered states of consciousness. The tools for obtaining data were databases and questionnaires for growers and people with experience in using the studied species.

Serotonergic hallucinogenes and their therapeutic use
Bouberl, David ; Novotný, Jiří (advisor) ; Vejmola, Čestmír (referee)
Serotonergic hallucinogens are a group of substances that induce changes in consciousness based on their affinity for some of the serotonin receptors - especially 5-HT2A. The best known substances in this group include LSD, psilocybin or mescaline. During the 1950's and 1960's, initial research into the therapeutic uses of these substances took place, but studies from this period did not meet today's methodological standards. However, the results of recent studies point to the potential therapeutic use of psilocybin or LSD in the treatment of depression / anxiety, addiction and OCD. The aim of this work is to summarize current knowledge about selected serotonergic hallucinogens, their chemical properties, mechanisms of action and especially about the possibilities of using these substances in psychotherapy.

Impact of psychoactive drugs on the central nervous system
HRUBEŠOVÁ, Tereza
Substances of various origins belong among psychoactive drugs. These substances impact the central nervous system, where they affect cerebral function and cause temporary changes in perception, mood, consciousness and behaviour. This thesis presents a review of hallucinogens. Intoxication by these substances induces a state reminiscent of trance, dreaming or meditation which is exploited for recreation, ceremonial and mythological purposes around the world. Classification of psychoactive substances can be performed by many criteria, ranging from origin and chemical composition, through their effects on the central nervous system, to their legislative status. The first known use of psychoactive drugs dates to the Paleolithic period (2 500 000 A.C.N. - 8 000 A.C.N.). Their usage varies greatly among cultures; drug commonly used in one culture can be unknown to another one. Usage and popularity of psychoactive drug differ in ritual habits in cultures and across continents. In this Bachelor thesis, the mechanism of impact and signs of intoxication by six compounds are described. These include ibogaine, tropane alkaloids, harmala alkaloid, psilocybe, dimethyltryptamine and mescaline. Cultural and historical context is also provided.
