What immediate physiological change is commonly associated with marijuana use?

The immediate physiological change commonly associated with marijuana use is an increased pulse rate. When marijuana is consumed, the psychoactive compound THC (tetrahydrocannabinol) interacts with the endocannabinoid system in the body, which can stimulate the cardiovascular system. This interaction often results in an elevation of the heart rate, as the body responds to the effects of the drug.

Increased pulse rate can occur shortly after use and is considered one of the more immediate physiological responses. This cardiovascular response is important in understanding how marijuana can affect physical performance and overall health. It’s critical for individuals, especially athletes, to be aware of these effects as they may influence exercise capacity and recovery.

Other physiological changes, such as increased appetite and decreased alertness, while associated with marijuana use, are typically not as immediate as the increase in pulse rate. Lower body temperature is also not a common immediate effect; in fact, marijuana may cause a slight increase in body temperature due to its effects on circulation. Understanding these physiological responses is important for those studying athletic training and the implications of substance use on performance and health.
