A Clearer Look at Cannabis

If you choose to use cannabis, the kind of experience you’ll have depends on many factors – what type of product you use, how you use it, how much you use, how much THC and CBD are in the product, and more. It’s important to be mindful of these things before using to ensure a positive and safe experience for you and those around you.

High-THC Products

THC levels in cannabis products have risen significantly over the past few decades. In the mid-1990s, most products contained around 5% THC. Today, many have more than 35%.

Concentrates such as shatter, wax, budders, and oils have higher THC levels (average 69%, some over 90%) compared to cannabis flower (average 21%). Potency can vary by product, so it’s important to know what you’re using. Start with a low dose and go slow. Remember, edibles can take up to three hours to kick in and may last up to 24 hours.

Cannabis can impact both mental and physical health. Some people experience panic attacks, paranoia, hallucinations, increased heart rate, dizziness, and nausea. And high-THC products can increase the risk of these negative effects.

Look for two symbols on every legal cannabis product. The “Universal Symbol” indicates the product contains THC and is for adults 21+. The “Not For Kids” symbol helps prevent youth access.

FAQs

When buying cannabis, it is important to always buy from a licensed retailer. Legal products will have the “Universal Symbol,” which means they contain THC and are approved for purchase by adults 21 and older. Some producers may illegally add this symbol to their products, so be sure to also look for where the product is sold and if THC levels are within legal limits.

There’s no one-size-fits-all answer. If you choose to use cannabis, start with a low dose and wait to feel the effects before taking more. This reduces the risk of overconsumption and helps you have a safer experience.

Not necessarily. Higher THC levels can increase the risk of negative health outcomes and addiction—especially for youth.

Mixing cannabis with any substance can have unintended risks and consequences. Consuming cannabis with alcohol, called “crossfading,” can heighten the risks and side effects of both substances, worsening impairment. It can lead to nausea, vomiting, panic attacks, anxiety, and paranoia. If you take prescription drugs, consult with your primary care provider before using cannabis as it can interfere with the medications you’re taking.

Too much cannabis can cause symptoms like anxiety, paranoia, rapid heart rate, high blood pressure, nausea, vomiting, or extreme confusion. Call 911 for medical emergencies like a seizure, trouble breathing, or if someone can’t be awakened. For non-urgent issues, contact the Washington Poison Center online or call (800) 222-1222. If you think your pet has consumed cannabis, contact the ASPCA Animal Poison Control Center at (888) 426-4435 or your veterinarian.
