Federal laws are enforced by Federal government and apply to all individuals in the country, while State can enforce its own State laws to be enforced on people living in its territory. The Constitution specifies only a few state powers. (Harrison, Page 95). Supremacy Clause establishes that State laws are subordinate to Federal Laws.In the United States, the use and possession of cannabis is illegal under federal law for any purpose, by way of the Controlled Substances Act of 1970, but the recreational use of cannabis is legal in states like Colorado, Washington, California, Nevada to name a few, and few other state have decriminalized marijuana uses.More states are open to decriminalizing the use of recreational marijuana, and increase revenue through taxation on marijuana consumption, while the federal government is adamant about criminalizing marijuana uses, even in the state where marijuana is legalized. Because of the supremacy clause, federal laws against marijuana supersede any state laws and it can be punishable even in a state where marijuana is legal.Same-sex marriage has been legal when the United States Supreme Court ruled in its favor declaring the ban on same-sex marriage unconstitutional.Some states like Texas, Arkansas, Georgia etc criticized this ruling and questioned the validity of the new law. They iterated Marriage should be a union between a man and a woman. Some state went on as far as not issuing the marriage license to the same-sex couple, or not making any changes in their marriage forms to accommodate same-sex couple needs.
