Crimes
Many states have varying extents of marijuana legalization in which it may be medically legal, recreationally legal, or just decriminalized. Therefore, the crimes and punishments for marijuana-related crimes also vary. For example, in Alabama, you may go to jail for 20 years for possessing any amount of marijuana. However, in California, you must be selling to a minor to be arrested. Similar to the topic of employment and marijuana use, public opinion and policies are always changing, which will most probably warrant convictions and prison sentences to be adjusted as well.
