The Dark Side of Cannabis

Unnecessary Radiation Exposure: SPECT scans inject patients with radioactive isotopes. Critics—including retired family physician Dr. Harriet Hall and researchers—warn that exposing children and adults to radiation carries unnecessary health risks without proven clinical benefit.

As someone who worked directly in nuclear medicine in an engineering background I would like to add the fact that a SPECT scan exposes a patient to about the same amount of radiation as 2-4 years of normal background radiation. The isotope used has a half life of 6 hours.

"You can’t convince me that marijuana didn't give me schizophrenia"

Schizophrenia and Marijuana is all that proves I highly doubt its the Marijuana and more likely health of said body which made him seek said cannabis. Im one who knows the negatives of Marijuana I dont defend it all the time. I was skeptical of the health benefits until I seen how well it worked for my grandma's dementia wish she woulda keeped taking it.

Same ^

And what does that prove about schizophrenia and marijuana exactly; genuinely asking? Correlation absolutely -- causation ??

The 42% increased chance of stroke is scary enough ya don't have to make things up. Inhaling hot smoke is surely bad for you.

ps -- sounds like the radiation exposure to get this test is ALOT WORSE for you than choosing to smoke a joint that day instead...

Biological Function & Known Effects: CB2 receptors ~ key physiological mechanisms:

1. Anti-Inflammatory Regulation
When tissues are injured or inflamed, immune cells express more CB2 receptors. Activation of CB2 inhibits the release of pro-inflammatory signaling proteins (cytokines) and reduces immune cell migration to the site of damage, helping to control local and systemic inflammation.

2. Neuropathic & Inflammatory Pain Relief
Reduce pain indirectly by suppressing the release of inflammatory chemicals near pain-sensing nerve fibers.

3. Neuroprotection
Neurodegenerative conditions (such as Alzheimer's, Parkinson's, or multiple sclerosis) or after traumatic brain injury, brain microglia. CB2 receptor activation on these cells helps dampen inflammation, protecting surrounding neurons from further damage.

4. Tissue Repair & Remodeling
Stimulating bone formation and inhibiting bone breakdown as well as in managing fibrosis (scar tissue formation) in organs like the liver and kidneys.

THC (Delta-9-THC) Partial Agonist ~ Binds directly to CB2, contributing to anti-inflammatory and pain-relieving effects.

CBD (Cannabidiol) Indirect Modulator Low affinity for binding directly, but acts as an inverse agonist/antagonist at CB2 and inhibits the breakdown of endocannabinoids (like 2-AG), enhancing the body's natural anti-inflammatory signaling.

Beta-Caryophyllene (Terpene) Full Agonist A dietary terpene found in cannabis that selectively binds directly to CB2 without touching CB1, providing purely anti-inflammatory benefits without any intoxicating effects.Medical Research & Potential Therapeutics
CB2 can be targeted without triggering intoxication, dizziness, or cognitive impairment, it is a prime target for pharmaceutical development.

CB2-selective therapies: Autoimmune diseases (e.g., Rheumatoid arthritis, Inflammatory Bowel Disease) Chronic pain management (especially neuropathic pain) Neurodegenerative conditions (such as ALS, Multiple Sclerosis, and Alzheimer's disease) Fibrotic conditions (liver cirrhosis and pulmonary fibrosis).
