Yes, but merely on principle. I think alcohol and tobacco should be straight up banned unconditionally. Society resists this, so they banned them for children instead and called it a day.
I don't accept these ineffectual political concessions. If a thing is bad for children, then it's in all likelihood just as bad for the adults as well. So go all the way and ban it for everybody, not just children. Do it right, don't come up with these half measures that dehumanize children as a side effect.
