Let's just say I had an experience once with a brownie and I know what the effects are. I don't smoke weed as a rule but I know plenty of people who do, including my parents. As far as who smokes or ingests it does not matter except for the fact that it IS pacifying in many ways. THC affects perception/awareness among other things...the more you smoke the more removed from reality you can become. I think that is the point of smoking weed but being active often requires being alert and clear.
