How bad are weed and truffles for your brain? do i have a bigger chance on cancer? i do truffles once per week, weed twice.

Risk unclear: I can't recommend taking anything to make you goofy, even alcohol. No one has linked cannabis or psilocybin to brain tumors or grave injury. Heavy cannabis users do seem dim to others. If you do choose to do this -- and i know it's legal in the netherlands -- remember that you're at your peak for learning, developing yourself socially and professionally and physically -- why do drugs instead?
