Additional Information​

• Stimulants: these drugs block the reuptake and reabsorption of neurotransmitters such as serotonin and dopamine which can lead to increased energy, panic, and anxiety. e.g. Nicotine and caffeine.
• Depressants: increase the production of neurotransmitter GABA (Gamma-Aminobutyric acid), which in turn reduce nervous system activity and induces sleep e.g. Benzodiazepines.
• Narcotics: These stimulate the release of endorphins which are neurotransmitters that reduces pain, hence used as analgesics e.g. morphine and codeine.
• Hallucinogens: These are warped a person’s sense of time and space hence tricking the brain into seeing or hearing things that aren’t actually present i.e. hallucination. e.g. LSD.
• Sedative drugs: are tranquillizers that act as CNS depressants and induce sedation by increasing the activity of GABA neurotransmitters.
• Epichlorohydrins: ECH is derived from propylene and is used mainly for the manufacture of glycerol and unmodified epoxy resins and, to a lesser extent, in the manufacture of elastomers, water treatment resins, surfactants, ion exchange resins, etc. It is a strong irritant and acutely toxic following oral, percutaneous, subcutaneous, and respiratory exposure. Death may result due to effects on the central nervous system and the respiratory center.
• Alcohol: is also called ethanol and it leads to depression of the Central nervous system that is slowing down nerve activity and brain functioning.
