I'm sick of people suggesting that weed is a detrimental drug. It's not. Think for yourselves and don't let the governments control every aspect of your lives.
It's not detrimental in the sense that cigarettes is with all of its toxins and affinity to brain receptors, but marijuana's smoke does contribute to lung cancer (any smoke being inhaled and taken in, basically), and that's why I choose not to smoke it. I know that people can argue that our own polluted air does the same thing, but I would rather just stick to our semi-clean air than smoke altogether.
