Of course it's not totally harmless; nothing is totally harmless. You can kill yourself drinking too much water. Pot doesn't make you stupid. Being born stupid and being too closed minded to learn about new things is what makes you stupid. Some of the smartest and wealthiest people I know smoke daily. I know someone very well who retired in his mid 30's with several hundred million dollars and is a genius who smokes. He has an MBA from Wharton school of business and was asked to be the dean of Duke Univ. school of business. He was also recently asked by our Gov. to create and head a committee to try and reform the financial system. I can't talk about the bigger and more impressive things he's done because if I did someone would possibly be able to figure out who he is. I know several other very well off people that smoke. Those type of people don't just come out and say it though. More people than you think do it but since it's illegal and they have a lot to lose they have to be very very careful about keeping it a secret. There are also idiots that do it but half the world seems like idiots so that proves nothing. People are addicted to coffee; everything is addicting. Maybe you should try listening to "ALL of your best friends and half of your immediate family". Maybe they know something that you are too closed minded to learn about. You call ALL your best friends and half your family stupid yet you make a post with nothing but stupid and condescending remarks about something you obviously know nothing about. Brainwashed much?
