Use of Regulated Marijuana Concentrate

Regulated Marijuana Stores offer various categories of marijuana concentrates. Stores may refer to marijuana concentrates using different names, including but not limited to terms like shatter, wax, butter, sugar, hash, resin, and rosin.

Start Low. Go Slow.

Vaping: Vaporizers heat marijuana concentrate to release THC for inhalation. The serving size should not exceed one inhalation lasting two seconds per serving.

Inhalation other than Vaping: When consuming regulated marijuana concentrate by inhalation other than vaping (e.g. dabbing) the recommended serving size is a sphere with the diameter no larger than the dot in the picture. 

Risks and Precautions


Use of Marijuana Concentrate may lead to¹:

1. Psychotic symptoms and/or Psychotic disorder (delusions, hallucinations, or difficulty distinguishing reality);

2. Mental Health Symptoms/Problems;

3. Cannabis Hyperemesis Syndrome (CHS) (uncontrolled and repetitive vomiting);

4. Cannabis use disorder / dependence, including physical and psychological dependence.

Consuming concentrate via inhalation will cause immediate effects.

Marijuana concentrates ARE NOT recommended for inexperienced marijuana users. THC concentration (% THC), amount of concentrate consumed, and frequency of use can result in both short and long-term effects. There is moderate evidence that individuals who use marijuana with THC concentration greater than 10% are more likely than non-users to be diagnosed with a psychotic disorder, such as schizophrenia. Marijuana concentrate is not approved by the FDA and claims of medical benefits are not supported by the FDA. Marijuana concentrates ARE NOT recommended for anyone under age 25, except if recommended by a doctor. People under 25 may be at greater risk of potential harm because the brain is not fully developed. Regulated Marijuana Stores cannot provide medical advice. Any questions related to the health or safety of marijuana concentrates should be discussed with a patient’s recommending physician or an adult consumer’s primary care physician.

Other Statutory & Regulatory Labeling Requirements

Universal Symbol - Caution Symbol for Regulated Marijuana THC

All Regulated Marijuana must be sold in a Container that displays the Universal Symbol to caution that the product contains THC.

The following warning statements must be included on every Container of Regulated Marijuana:

•“Keep away from Children.”
•“This product was produced without
regulatory oversight for health, safety, or efficacy.”
•“There may be long term physical or mental health risks from use of marijuana including additional risks for women who are or may become
pregnant or are breastfeeding. Use of marijuana may impair your ability to drive a car or operate machinery.”

¹These risks are based on CDPHE evidence statements where there is either moderate or substantial evidence. Where moderate means strong scientific findings that support the outcome, but these findings have some limitations and substantial means robust scientific findings that support the outcome with no credible opposing scientific evidence.



The sale, transfer, or dispensing of marijuana in violation of Colorado law is a felony punishable by a prison sentence up to 32 years and/or fines up to
$1,000,000.00. A felony conviction can have serious consequences including the inability to vote while incarcerated, prohibition on obtaining a passport which is required to travel internationally, disqualification for employment, the inability to obtain housing and other serious consequences. Inhaling more than 10 mg of THC within 10 minutes can lead to a blood THC level above 5 ng which can be used to support a conviction for driving under the influence.
