The article focuses on the preparation or production and effects of biogenic (cannabis/marijuana/hashish, cocaine, morphine/opium), semi-synthetic (heroin, LSD) and fully synthetic (cannabinoids, opioids, phenylalkylamines, cathinones, tryptamines, benzodiazepines, arylcyclohexylamines, GHB/GBL, alkylnitrite) drugs.

However, it is becoming increasingly apparent that native amphibians could also be a previously overlooked but very rich source of bioactive peptides. Native species such as the grass frog, midwife toad and fire salamander produce skin secretions with antimicrobial, antiinflammatory, antitumour and/or wound-healing properties. Modified variants are even undergoing preclinical and clinical research. Nevertheless, some native species have not yet been analyzed for bioactive peptides in their skin secretions.
