Growing marijuana at home (so-called “home grows”) is illegal under US federal law.  However, according to the U.S. Sentencing Commission and the FBI 99% of marijuana arrests are made under state law, rather than federal law.  Furthermore, states aren’t required to enforce federal law. As a result, in most (though not all) situations, state laws effectively determine whether marijuana growers face criminal risk for their home grows.  And, state laws vary dramatically.

You can group states into essentially three groups, based on their cultivation laws:

• States where growing pot for recreational and medicinal use is illegal;
• States where you can grow pot for medicinal use
• States where you can grow pot for recreational use

States that allow recreational cultivation typically have restrictions on the number of plants that adults are able to grow.  Many of these states loosen these restrictions for registered patients growing for medicinal use.
