While cannabis doesn’t cause sunstroke by itself, it can certainly amplify what a person feels during an extremely hot day for some people. If you were already experiencing dehydration, fatigue, having consumed a large amount of alcohol, or spending a great deal of time exposed to direct sunlight then the effects of cannabis (i.e., dizziness, dry mouth, lightheadedness) could easily exacerbate these symptoms. As such, we recommend the responsible use of cannabis products during the warmer months.

What is sunstroke?

The term “sunstroke” is commonly used to refer to extreme illness caused by excessive heat or exposure to the sun. Medical professionals would classify sunstroke as either heat exhaustion or heatstroke; depending upon severity. The early warning signs can consist of headaches, heavy sweating, weakness, nausea, dizziness and extreme thirst. Heat stroke is far more severe and can result in the following: confusion, fainting, feverishly elevated body temperatures, and bizarre behavior.

In the event of a person experiencing adverse effects while exposed to excessive heat, remove them from the area, provide them with water and assist in cooling their skin. If the individual does not begin to show improvement contact a medical professional for assistance.

Does cannabis increase risk for worsening symptoms due to heat?

Yes. For many adults, yes. Cannabinoids can create alterations in how you perceive your body’s warning signals. For example, you might become so comfortable in the sun that you sit in it longer than you normally would and/or fail to recognize your thirst until dehydration has set in. Dry mouth is another common side effect of cannabinoids that creates a false sense of hydration status. This is particularly pertinent in festival settings or summer gatherings where individuals may consume large amounts of alcoholic beverages, dance excessively, walk extensively and/or forget to eat adequately.

Cannabis Safety Tips for Summer Use

Have plenty of water available and keep drinking throughout the day. Do not use cannabis in the full force of the mid-day sun if you have already spent several hours outside. Situate yourself in shaded locations, apply sunscreen and frequently take breaks inside or under cover.

Do Not Mix Alcohol & Cannabis During Hot Weather

Combining cannabis with excessive consumption of alcohol during periods of high heat can increase the likelihood of dizziness, nausea and poor judgment. Start slowly and allow sufficient time to adjust before increasing dosage. It is not ideal to experiment with your tolerance levels during summer months.

Best Approach for Extremely Hot Days:

Optimize relaxation rather than intensity. Consuming light foods in a shaded environment with access to clean water and maintaining a peaceful atmosphere will consistently enhance your overall experience. If you are too hot, dizzy, ill or disoriented, immediately cease activities and cool down. Do not attempt to push through.

Adults who responsibly use cannabis for relaxation purposes during the summer months can do so safely, however, respect the power of the sun and pay attention to your body as well as utilizing quality products from reputable retailers.

Here at Weed Wonderland, we firmly believe that summer should be enjoyed smoothly, safely and without unnecessary risk. Utilize sunscreen, remain hydrated and purchase high-quality cannabis products from a trusted U.K. retailer
