Medical Cannabis Research & History

Explore the rich history of cannabis as medicine and the modern science supporting its therapeutic use.

History of Cannabis as Medicine

Cannabis has been used medicinally for thousands of years across many cultures. Here's a timeline of its journey through history.

2737 BCE

Ancient China

Emperor Shen Nung documented cannabis use for medical purposes, including treatments for gout, rheumatism, and malaria.

1500 BCE

Ancient Egypt

The Ebers Papyrus references cannabis for inflammation and other ailments.

1000 BCE

India

Cannabis (bhang) used in Ayurvedic medicine for anxiety, pain, and digestive issues.

1839

Western Medicine

Irish physician William O'Shaughnessy introduced cannabis to Western medicine after studying its use in India.

1851-1941

US Pharmacopeia

Cannabis was listed in the United States Pharmacopeia as a treatment for various conditions.

1964

THC Discovery

Israeli scientist Raphael Mechoulam isolated THC, beginning modern cannabinoid research.

1988

CB1 Receptor

Scientists discovered the first cannabinoid receptor (CB1) in the brain.

1992

Endocannabinoid System

Discovery of anandamide, the first endocannabinoid, leading to understanding of the ECS.

2016

Florida Amendment 2

Florida voters approved medical marijuana for qualifying patients with 71% support.

Modern Research Areas

Scientific research continues to uncover the therapeutic potential of cannabinoids. Here are key areas of study.

Pain Management

Studies show cannabinoids can modulate pain signals through the endocannabinoid system, offering relief for chronic pain conditions.

Extensive research available

Epilepsy & Seizures

FDA-approved Epidiolex (CBD) for certain types of epilepsy demonstrates the therapeutic potential of cannabinoids.

FDA-approved treatment exists

PTSD & Anxiety

Research suggests cannabis may help regulate fear and anxiety responses, showing promise for PTSD treatment.

Ongoing clinical trials

Nausea & Appetite

Well-established use for chemotherapy-induced nausea and appetite stimulation in conditions like HIV/AIDS.

FDA-approved treatments exist

Neurodegenerative Diseases

Preliminary research explores neuroprotective properties for conditions like Parkinson's and Alzheimer's.

Early-stage research

Inflammation

Both THC and CBD show anti-inflammatory properties that may benefit conditions like Crohn's disease and arthritis.

Growing body of evidence

What Research Has Shown

Modern cannabis research has accelerated since the discovery of the endocannabinoid system in the 1990s. Scientists have identified over 100 cannabinoids and numerous terpenes that may contribute to therapeutic effects.

The "entourage effect" theory suggests that cannabis compounds work better together than in isolation, which is why whole-plant medicine may be more effective for some patients than isolated cannabinoids.

While research is promising, it's important to note that cannabis remains a Schedule I substance federally, which has limited large-scale clinical trials in the United States.

WHO recommendation to reschedule cannabis (2019)
"Cannabis is remarkably safe. Although not harmless, it is surely less toxic than most of the conventional medicines it could replace if it were legally available."
— Lester Grinspoon, M.D., Harvard Medical School
Author of "Marihuana Reconsidered" (1971)
