What is Crossfading, and How Should You Teach About It?

Get up-to-date on this important driving education topic.


What is crossfading? Crossfading is another term of polydrug use, the use of multiple substances — like THC and alcohol — at one time.In the field of safe driving, drug, and alcohol awareness education, we’ve seen one topic become increasingly prevalent over the past few years: crossfading. 


But what is crossfading, and how should you address it in your education programs?


What is crossfading?


Crossfading is another term for polydrug use, the use of multiple substances, such as alcohol and marijuana/THC/cannabis, at one time. While using these substances on their own can cause harm, using them together increases the risk of dangerous side effects such as dizziness, heart palpitations, paranoia, and panic attacks.


Research has shown that using alcohol and marijuana together may amplify the effects the substances have on their own, with alcohol increasing the body’s absorption of THC from marijuana products. The increased effects of these substances used together can also severely impact people’s attention and driving skills, raising the risk of a crash.


How should I teach about crossfading?


While you may not have taught students about the dangers of crossfading or polydrug use before, you can build your lessons using the curriculum you’ve used to raise awareness about drugs and alcohol used by themselves.


Possibly the most important guidance we can offer is to make sure your lessons are engaging and incorporate hands-on activities, like the Fatal Vision® Polydrug [Alcohol & Marijuana] Goggles Program Kit, to hold students’ attention and safely illustrate the dangers of crossfading. By keeping them engaged, students are more likely to retain the information you teach and carry those lessons with them out in the world.


You can also incorporate facts and statistics about crossfading to help stress the dangers of simultaneous substance use and the negative impact it has on driving abilities. When students learn about the real-world impacts of crossfading, they’ll be more likely to think twice before using alcohol and cannabis together.
