Not for me to say. I can comment, however. There is no scientific rationale to support the thesis that a marijuana free life is necessarily less worthy or pleasant than a marijuana engaged life. And that's not for lack of looking for evidence.
I would prefer that my children not experiment with marijuana in their formative years, for many of the same reasons I'd prefer that they not engage in sex then, either. It does not follow that I condemn either sex or marijuana. And it particularly does not follow that I think throwing them, or the kids that sold it to them, in jail is a great plan. It is, in fact, an abysmally stupid plan, rather like setting grandpa afire to remove a food stain from his shirt.
