All laws involve morality. It is immoral to murder, steal, assault, rape, slander, extort, etc etc.
Pretending that laws have nothing to do with morality is specious and irrational.
Crimes we need law enforcement to punish are those like you listed, all covered in God's Law known as the Ten Commandments. We are discussing a law concerning consenting adults buying, selling and using a product. A product soon to be legal here in Colorado.
Crimes requiring law enforcment also require a victim. For example, if a person driving under the influence harms another person or property, punishment is required. Some innocent got victimized. Growing, preparing and smoking pot in one's home victimizes nobody.
People growing pot in closets, or Mexican drug cartels. Colorado decided which we prefer. Any who do not like it are free to ski and camp in other states. The grand experiment of these United States...

Thanks for pointing that out.
That “you can’t legislate morality” is one of the silliest sophistries one can utter, and yet it is heard again and again.
Virtually every law of any consequence is intended to advance “morality,” or somebody’s idea of it anyway.
