Discuss the trend in the use of psychoactive plants as the world has become more interconnected.
Historically, psychoactive plants were used ritually and medicinally, especially by shamans for spiritual purposes.
With globalization, these substances became separated from their cultural context and were increasingly used recreationally.
This shift led to stigmatization, legal prohibition, and later, partial re-acceptance (e.g., cannabis legalization, psychedelics for therapy).
Some remain criminalized, while others (like caffeine) are widely accepted.
Distinguish the primary categories of psychoactive plants in terms of their physiological and psychological effects, and provide examples of each
Depressants (slow down CNS activity)
Effects: Reduce anxiety, pain, promote sleep
Examples:
Opium (Papaver somniferum): morphine, codeine, heroin
Valerian (Valeriana officinalis): sleep aid
Cannabis (THC) in moderate-high doses
Stimulants (increase CNS activity)
Effects: Heightened alertness, suppressed appetite, elevated mood
Examples:
Caffeine (coffee, tea, cacao)
Nicotine (tobacco)
Cocaine (coca plant)
Ephedrine (Ephedra)
Hallucinogens (alter perception)
Effects: Visual/auditory hallucinations, sense of unity, time distortion
Examples:
Mescaline (peyote)
DMT (ayahuasca)
Salvinorin A (Salvia divinorum)
Lysergic acid derivatives (morning glory seeds)
Identify the origin of Cannabis and discuss factors that led to its prohibition, and current trends in regulation of the plant
Origin:
Native to Asia, first used in China for fiber and oil.
Religious use in India (bhang, ganja, charas).
Bred for high-resin female flowers → increased THC content.
Prohibition history:
1937: U.S. bans cannabis (racially motivated rhetoric played a role).
1970: Controlled Substances Act categorizes cannabis as Schedule I (most restrictive).
1980s: Reagan’s Anti-Drug Act increases penalties.
Current trends:
Legal for medical use in many states since 1990s.
Now legal for recreational use in over 18 states + DC.
Still illegal under federal law, but enforcement is easing.
Florida's 2024 ballot initiative for recreational use did not pass, but momentum is growing.
Outline the history of opium including the development of different ways of administering the drug, and describe the effects on society
Early use:
Used by Sumerians (~3000 BC).
Originally eaten, later smoked (17th century China → opium dens).
Opium Wars:
British traded opium from India to China to offset trade deficits.
Chinese resistance led to wars and forced opium imports.
Administration methods:
Laudanum: opium + alcohol; 19th-century "medicine."
Injection (morphine): began post-1853 (hypodermic syringe).
Heroin: created in 1898, thought to be safer than morphine — turned out to be more addictive.
Modern impacts:
Opiates (morphine, codeine) still used medically.
Massive opioid addiction crisis in the U.S. (>70,000 overdose deaths annually).
Contrast hallucinogens with other categories of psychoactives
Category | Mechanism & Effects | Examples |
Depressants | Calm the CNS, reduce anxiety and pain | Opium, valerian, alcohol |
Stimulants | Activate the CNS, increase energy, alertness | Caffeine, nicotine, cocaine |
Hallucinogens | Alter perception; sensory distortions, "spiritual" or mystical states | Mescaline (peyote), DMT (ayahuasca), LSD |
Hallucinogens are generally:
Not addictive
Non-lethal at common doses
Historically used in rituals
Often regulated more harshly despite low harm
