In the US, there are state and federal laws that do not agree if cannabis is legal or not. Some states such as Colorado and California are completely legal for use of cannabis in all forms including flower, hashish, edibles, tinctures, hash oil and even flavoured or alcoholic drinks for adults 21 or over excluding some laws for the quantity you can possess, distribution and where you can smoke in these states. In other states, cannabis in all forms excluding perhaps Cannabis Ruderalis (hemp) is only legal for medicinal use but much less strict than Australia for example. In some other states cannabis is classed as a Schedule 1 drug meaning severe and unreasonable punishments for possession, use and distribution.
