Medical Toxicology of Drug Abuse: Synthesized Chemicals and Psychoactive Plants

Medical students: abuse of psychoactive substances and sexuality aspects.

UNLABELLED University students aged 17 to 24 years of age are prone to many risk factors. OBJECTIVES Identify risk factors related to exploring sexuality and characteristics of consumption of psychoactive substances in students attending medical school. METHODS 465 Medical students from Santa Casa of São Paulo Faculty of Medical Sciences (FCMSCSP) were prospectively and transversely evaluat...

Psychoactive prescription drug use disorders, misuse and abuse Pharmacoepidemiological aspects

ii Psychoactive prescription drug use disorders, misuse and abuse iii All the passionate work I put into this thesis is dedicated to my parents, who always emphasized the importance of knowledge and of caring for the less fortunate. Background: There is a widespread and increasing use of psychoactive prescription drugs, such as opioid analgesics, anxiolytics, hypnotics and anti-epileptics, but ...

Nature's chemicals and synthetic chemicals: comparative toxicology.

The toxicology of synthetic chemicals is compared to that of natural chemicals, which represent the vast bulk of the chemicals to which humans are exposed. It is argued that animals have a broad array of inducible general defenses to combat the changing array of toxic chemicals in plant food (nature's pesticides) and that these defenses are effective against both natural and synthetic toxins. S...

Predictive Toxicology and Mixtures of Chemicals

All predictive toxicological models concern individual chemicals. An exposure to a mixture of chemicals is the reality, however. Toxicity of an individual chemical itself or in a mixture with other chemicals may significantly differ. The presentation shows our attempt to find a suitable model for a prediction of acute toxicity of binary mixtures of organic chemicals. We have suggested a molar r...
