Study Notes
Opiates and Neurotransmitters
-
Heroine mimics natural opiates, inhibits dopamine suppression, resulting in a surge of dopamine and enhanced feelings of well-being.
-
Affects brain areas related to pain signals, stress response, and emotional attachment.
-
Ecstasy imitates serotonin, prompting transporters to release serotonin, leading to overstimulation of the cell.
-
Impacts brain functions related to mood, sleep, perception, appetite, and indirectly influences the reward pathway.
Cannabis and Stimulants
-
Marijuana contains THC, which mimics anandamide and inhibits dopamine suppression.
-
Affects brain functions, impacting short-term memory, movement speed, and inducing a calming effect.
-
Meth mimics dopamine, forcing it out of cells and causing excessive stimulation in the synaptic cleft.
-
Highly addictive, it primarily targets the brain's reward pathway.
Alcohol and Cocaine Effects
-
Alcohol enhances GABA receptor inhibition and blocks glutamate receptors, dampening excitatory signals in the brain.
-
Affects memory, decision-making, and impulse control.
-
Cocaine obstructs dopamine transporters, resulting in prolonged dopamine receptor binding and overstimulation.
-
Influences the reward pathway and voluntary movement, leading to increased fidgeting in users.
Hallucinogens and Addictive Molecules
-
LSD binds to serotonin receptors, exhibiting both inhibitory and excitatory effects.
-
Influences areas of the brain like the locus coeruleus, impacting wakefulness and inducing hallucinations.
-
Dopamine is recognized as the master molecule driving addiction, connecting substance use to the brain's reward system.
Substance Use Trends and Influences
- 40% of alcoholism can be traced to genetic factors.
- The progression to cocaine use often follows patterns of using cigarettes, alcohol, and marijuana.
Drug Policy and Education
- The 18th Amendment initiated prohibition, reducing alcohol sales but increasing violence and gang activity, while the 21st Amendment repealed it.
- Effective prevention and reduction of drug use are heavily influenced by policies and price strategies.
Social and Economic Impacts of ATOD
- Drug abuse leads to family stress, crime, poverty, and a decline in societal work ethic.
- Economic costs of alcohol, tobacco, and other drugs are felt at family, corporate, and government levels.
Withdrawal and Addiction Characteristics
- Withdrawal symptoms typically oppose the effects of the substance the user is dependent on.
- Alcohol is noted for having the most severe withdrawal symptoms, while cocaine carries the highest reinforcement factor.
Demographic Patterns in Substance Use
- Smoking prevalence is highest among individuals with less than a high school education, while most users of cocaine are Hispanic.
- Alcohol consumption peaks in the 18-25 age group, with 19% of adults in the USA smoking and 42% abstaining from alcohol.
Gateway Drugs and Marketing Strategies
- Common gateway drugs include tobacco, alcohol, marijuana, and inhalants, leading to higher chances of substance use.
- Advertising effectively targets different demographics, particularly women, using strategies centered on product information and emotional appeal.
