Tetrahydrocannabinol (THC) is the ingredient in marijuana that causes people to get high. There are several types of THC, and delta-8 THC is the subtype that is thought to affect blood pressure. Animal experiments with delta-8 THC show that it can cause temporary increases in blood pressure. Research shows that this is potentially due to a vasoconstrictor effect that causes arteries to narrow and contract, increasing blood pressure, which raises concerns about its use alongside illegal drugs.

The PCC states that delta-8-THC can cause harmful reactions if more than one “dose” is taken. Some of those reactions, Scharman says, can affect mental functioning, breathing and the heart. It can also be dangerous if a child takes a single dose.
