Attention: Because smoking is associated with more severe coronavirus (COVID-19) outcomes, avoid smoking altogether. There is also evidence that vaping is associated with increased risk for COVID-19. Sharing devices may also spread coronavirus as well as other viruses and bacteria. 

On this page, we are defining cannabis use as consuming cannabis plant products containing Tetrahydrocannabinol (THC).  THC is the primary psychoactive chemical in cannabis.  Cannabis plant products containing THC may be the leaf or flower of the plant, or extracts such as waxes or oils.  These products may be consumed by smoking, vaping, eating or drinking.

If you want to reduce your cannabis use

T-Break: a guide to help support a cannabis tolerance break is an online guide to assist with taking a break from cannabis use to reduce tolerance. People who use cannabis can build up a tolerance to it meaning that it takes more and more over time to get the same effects. Taking a break from cannabis can reduce tolerance. The guide is based on what college students say worked and did not work for them when they took a break. While the guide is located on the University of Vermont website, it is free and available to everyone.

This guide also has practical tips for cutting down cannabis use.
