Study Notes
Psychoactive Drugs Overview
- Psychoactive drugs influence consciousness by interacting with neurotransmitters at the synapses in the central nervous system (CNS).
- Neurotransmitters are chemical messengers crucial for communication between nerve cells.
Types of Psychoactive Drugs
- Stimulants: Block reuptake of dopamine, norepinephrine, and serotonin, enhancing their effects. Common examples include caffeine and amphetamines.
- Depressants: Decrease CNS activity, leading to sedation and relaxation. Examples include alcohol and benzodiazepines.
- Opioids: Activate opioid receptor neurons, resulting in euphoria, pain relief, and effects like slower breathing and constipation. Common opioids include morphine and oxycodone.
- Hallucinogens: Alter perception and sensory experiences. Examples include LSD and psilocybin.
Purpose of Psychoactive Drug Use
- Psychoactive drugs can simulate natural states of consciousness, such as relaxation or drowsiness.
- Medications like sleeping pills are prescribed to induce sleep, whereas benzodiazepines aim for relaxation.
- Some users seek psychoactive drugs for pleasurable experiences or to escape reality.
Drug Dependency and Tolerance
- Tolerance: Increased dosage required to achieve the original drug effect, leading to higher consumption.
-
Dependence:
- Psychological Dependence: Strong desire for the drug with no serious physical withdrawal symptoms.
- Physical Dependence: Withdrawal symptoms manifest when the drug is not used, including pain, irritability, and cravings.
Withdrawal and Addiction
- Withdrawal describes negative symptoms that occur when reducing or stopping drug use, which may include physical pain and strong cravings.
- Addiction is characterized by a compulsive drive to use the drug despite negative consequences, including physical, social, and legal issues.
