What is cannabis? A clear definition
Cannabis, also known as marijuana or weed, is a plant—Cannabis sativa—whose dried leaves, flowers, stems, and seeds are used for their mind-altering effects. The main psychoactive compound is THC (tetrahydrocannabinol), which produces the "high." Another key compound, CBD (cannabidiol), is non-intoxicating and often associated with therapeutic benefits.
When you consume cannabis, THC interacts with your body's endocannabinoid system, specifically cannabinoid receptors in the brain and nervous system, leading to changes in mood, memory, appetite, and pain perception. The plant comes in various strains, each with different levels of THC and CBD, affecting the experience.
Cannabis is used both recreationally and medicinally. In California, it's legal for adults 21+ and for medical patients 18+ with a valid ID. Our team at Cornerstone Wellness, a 3x award-winning dispensary in Eagle Rock, has nearly 18 years of experience helping people understand and choose cannabis products safely.
How cannabis affects your body and mind
Effects vary by person, strain, and method. Here's a quick breakdown of short-term and long-term impacts.
| Effect | Short-term | Long-term |
|---|---|---|
| Brain & mood | Euphoria, relaxation, altered perception, heightened senses | Potential memory issues, especially with heavy use starting young |
| Body | Increased appetite, dry mouth, red eyes, faster heart rate | Respiratory issues if smoked, possible dependence |
| Coordination | Impaired motor skills, slower reaction time | Risk of accidents if driving under influence |
| Mental health | Temporary anxiety or paranoia in some | May worsen anxiety or depression in vulnerable individuals |
| Addiction | Not immediate, but can develop | About 1 in 10 users become addicted; higher if starting young |
These are general patterns—your experience may differ. Always start low and go slow, especially with edibles.
