Confused about what THC actually is? You're not alone—and here's the truth. THC (tetrahydrocannabinol) is the main psychoactive compound in cannabis that creates the "high" feeling, and understanding it matters more now than ever.
Why This Matters Now
If you remember cannabis from decades ago, today's products are dramatically different. Between 1995 and 2022, THC potency quadrupled from 4% to over 16%, with some dispensary products reaching 40% or higher. This isn't your 1970s marijuana—it's significantly stronger, which changes both benefits and risks.
What THC Actually Does
THC works by binding to cannabinoid receptors in your brain and body, affecting mood, memory, pain perception, and appetite. According to the National Institutes of Health, synthetic THC (dronabinol) is FDA-approved for chemotherapy-induced nausea and AIDS-related appetite loss.
The Real Risks After 50
❌ Myth: Cannabis is completely safe and non-addictive
✓ Fact: About 30% of regular users develop cannabis use disorder (NIDA, 2024)
❌ Myth: It's the same as it was decades ago
✓ Fact: Stanford Medicine researchers found THC causes blood vessel inflammation and links to 29% increased heart attack risk
What You Should Know
After 50, your metabolism slows, meaning THC stays in your system longer and can interact with medications like blood thinners. Cleveland Clinic reports smoking cannabis increases stroke and heart disease risk—conditions already more common in older adults.
Your Next Step
You're already ahead by learning this. Talk with your doctor before trying cannabis, especially if you take other medications or have heart conditions. Many people find safer alternatives for pain, sleep, or anxiety work just as well. You've got this.
