As long as he stays off the dole, and doesn't ask for free medical care for the complications from pot smoking, no. But he is failing his responsibility to himself.
If one grows his own, and wants to go through life stoned and stupid, that is his decision.
Not now it isn't. Do you agree that it should be?
Balderdash. Most pot smokers never get busted for smoking, so they have that decision. The same if I decide to speed. But both have their consequences.
Liberty may not be "beneficial"
According to the Christian ethic, drug use is not a liberty, it is a vice, as is drunkenness (but not drinking per se, and there is a difference).
Liberals argue that Obamacare is "beneficial to society as a whole"
They can say that, but it doesn't make it true. My point was that pot smoking is neither beneficial to the user OR to society, and it is a vice that shouldn't be legalized.
Says who? Can you cite chapter and verse for these claims?
