In the United States, each of the states has distinct laws that do not interfere or supersede that with the federal laws in the constitution.
Having said this, in a state like Hawaii, there are some laws in existence that are different from other states. For example, in Hawaii, there is a hundred percent ban on gambling.
Similarly, there is partial legality on the use of marijuana which is only available for medical use and the patients must present state-issued medical marijuana cards.
