The rules for purchasing cannabis are as follows –
You must be 21 years of age or older to legally purchase cannabis and must provide proof of age such as a driver license or passport. You can purchase in the state of Colorado even if you are not a resident of Colorado.
It is illegal to give or sell cannabis to anyone under the age of 21. Do not provide cannabis to minors!
You should only purchase from a licensed dispensary.
An individual is only allowed to purchase 1 ounce of cannabis per day.
The Marijuana Enforcement Division (MED) in Colorado performed some studies to determine what the THC equivalent of concentrates and edibles are in relation to marijuana in flower form. They argue that since products such as concentrates have a much higher level of THC, then you shouldn’t be able to purchase the same amount of concentrates as you can flower. As a result, the MED has issued ‘Marijuana Equivalency’ guidelines. As of October 1st, 2016, the following rules are in effect in regard to recreational sales: 1oz Flower = 8g of Concentrate (Shatter, Wax, etc.) 1oz Flower = 800mg of Edibles You can still mix and match, but it does get a bit confusing. For example, you could purchase 2 grams of concentrate, but then you will be limited to 3/4 oz of flower (as they count the 2 grams of concentrate as the equivalent of 1/4 oz of flower).
The rules for possessing and using are as follows -
An individual is only allowed to have 1 ounce in his or her possession.
All public use is illegal – that means no smoking, vaping, or eating edibles in a restaurant or bar, outside in a park or on a sidewalk, at a concert, on the slopes, or in national parks and national forests. Use is intended in private places only.
It is illegal to drive while under the influence of cannabis.
Cannabis use when pregnant is unsafe. Use during pregnancy may have legal consequences, so simply don’t do it.
