What Is Marijuana?

Marijuana is a green, brown, or gray mix of dried, shredded leaves, stems, seeds, and flowers of the Cannabis sativa plant. The plant contains more than 100 unique compounds called cannabinoids, but the two most studied are THC and CBD (cannabidiol). THC causes the “high” associated with marijuana, whereas CBD is non-intoxicating and often used for its potential therapeutic benefits.

How Does Marijuana Work?

When you smoke, vape, or eat marijuana, THC rapidly travels from the lungs or gut into the bloodstream and reaches the brain. There, THC activates cannabinoid receptors, especially in areas involved in pleasure, memory, thinking, coordination, and time perception. This signaling release of dopamine produces the feeling of being “high” and can also alter senses, appetite, and reaction time.

Potential Effects and Health Impacts

Short-Term Effects

Short-term effects can include altered senses, mood swings, impaired body movement, difficulty thinking or problem-solving, and increased appetite. Usage can also impair memory and driving ability, and can cause anxiety, paranoia, or panic in some people, especially at higher doses.

Long-Term and Medical Considerations

Regular use, particularly during teen years, may affect brain development and cognitive function. Smoking marijuana can harm lung tissue and increase the risk of chronic cough and bronchitis. While the FDA has approved laboratory-produced THC drugs for nausea and appetite support and a CBD-derived drug for certain seizure disorders, whole-plant marijuana is not FDA-approved for treating any disease. Still, many states permit medical marijuana programs to manage chronic pain, chemo-induced nausea, spasticity, and other conditions.

Marijuana vs. CBD

A common confusion: marijuana is not the same as CBD. Hemp-derived CBD containing less than 0.3% THC is legal under federal law and does not produce a high. Marijuana, even high-CBD varieties, still contains significant THC and remains federally controlled. If you live in a state with legal recreational or medical marijuana, buying from a licensed and reputable dispensary ensures you get properly tested, accurately labeled products.

Legality of Marijuana in the U.S.

As enforcement changes, check your local laws. As of this writing, many states allow recreational marijuana while others have medical-only programs, and some still prohibit all use. Even in legal states, it is illegal to drive under the influence of marijuana, and federal penalties can apply on federal lands or if transported across state lines. Always consume responsibly and store products safely away from children and pets.
