Colorado stood as one of the pioneers in legal cannabis use in 2012 when Amendment 64 was passed stating that adults 21 or older could legally possess up to one ounce of marijuana or THC.

In addition to being able to buy cannabis for medical and recreational use, adults can also purchase cannabis seeds to grow their own in the privacy of their home. Those looking to purchase marijuana in Colorado will only need a government-issued ID to prove that they are of age. You do not need to be a resident of Colorado to purchase cannabis.

While Colorado may be ahead of the times, there are still some limitations to this amendment. Tourists visiting Colorado initially could only purchase up to 7 grams at a time. However, in June 2016 that rule was changed to allow both tourists and residents to purchase up to 28 grams at a time.

Those operating recreational marijuana stores are allowed to operate their business from 8 am to midnight. However, the official hours are determined by the city where the store is located.

Despite the overall acceptance of cannabis use in Colorado, there is still some regulations on where and when you can enjoy it. State laws urge you to be discreet and do not allow you to consume marijuana openly and publicly. While it is not a felony, you can receive a ticket for using cannabis in public. Still, there are some smoking lounges, discrete edibles, and vaporizers that make it easier to enjoy cannabis wherever you are.

Similar to alcohol use, it is illegal to drive while under the influence of cannabis. The legal limit in Colorado is 5 nanograms per milliliter of blood.

Remember, state laws concerning cannabis are constantly changing, so it's important to always research current laws prior to buying or enjoying recreationally.
