Dr. Anne Truong explains how cannabis impairs blood flow and lowers testosterone, recommends a 90-day break, and warns that fluoride mouthwash and many supplements with hidden prescription ingredients can worsen erectile function. She emphasizes diet, exercise, sleep, and stress as the foundation.

Questions this episode answers

Yes, weed is bad for blood flow; it can add to erectile dysfunction, anxiety, and paranoia. Stop using it for 90 days and get testosterone labs.

Indirectly, because fluoride in mouthwash kills oral bacteria that produce nitric oxide, reducing blood flow needed for erections.

Avoid over‑the‑counter products that may be tainted with prescription drugs, buy from trusted sources, look for USP or similar certification, and remember no supplement works without proper diet, exercise, sleep, and stress management.
