Laws and Regulations

California became the first state to allow medicinal cannabis use when voters passed the Compassionate Use Act in 1996. Today, cannabis is legal in California for both medicinal and adult (recreational) use.

The cannabis industry is strictly regulated to make sure:

  • Businesses operate safely

  • Products are contaminant-free and labeled to inform purchasers

  • Cannabis is kept away from children

Statutes, regulations and ordinances are all types of laws that work together to set rules for businesses and consumers.



Laws and Regulations

In November 2012, Colorado legalized marijuana for adults over age 21 by passing Amendment 64 to the Colorado Constitution.

The laws on legal marijuana use may seem confusing. This section is intended to give you a brief overview of legal adult use of retail marijuana. The laws regarding use and possession are different for medical marijuana.

Additionally, cities are allowed to pass even stricter laws. Learn more about how marijuana laws differ in each county and town across Colorado.


Laws and Regulations


On November 8, 2016, Nevada voters passed the Regulation and Taxation of Marijuana Act (Ballot Question 2). The Act legalized the purchase, possession, and consumption of adult-use cannabis for adults 21 and older. Even though cannabis became legal on January 1, 2017, how a consumer buys it, how much they can have at one time, and where they can use it are still restricted by the law.

The legalization of adult-use cannabis did not change the medical cannabis program.
