To say marijuana can be used everyday without ill effects is just foolish. I'm not here to say smoke or not, I'm strongly in belief of legalization and regulation but proper drug education first and foremost. Ill effects? Paranoia, anxiety, short term memory loss etc are all ill effects, temporary or otherwise. Putting smoke in your lungs is never good but can be mitigated by eating or vaporizing. Recent studies suggest smoking under 18 leaves lasting mental deficits.

Education is key, and I laugh at the thought of rogaine having more ill effects than cocaine.
All those effects you listed are completely mental. You don't get anxious because you smoke weed, you get anxious because you get anxious. Only you can control the way you feel, not anyone else, not an inanimate object.
Weed doesn't damage your brain, it lets you use the other side of your brain and realize that everything you were taught is bullshit.
