Pot can be great. Enjoyed it in my youth and still occasionally partake. I find it helps remove the 'background noise of everyday life' and leaves my brain to wander where it wants.
Pot has a lot of medical and recreational uses.
The criminal element that is a result of the illegality of pot is unfortunate. The socioeconomic hardship that results from this is also horrible.
I know that some may use pot to their detriment, but I don't think that justifies the criminalization of it.
Let people decide what they want for themselves.
