What is a known effect of cannabis abuse?

Cannabis abuse is widely recognized for producing effects that include euphoria and relaxation. The primary psychoactive component of cannabis, tetrahydrocannabinol (THC), interacts with cannabinoid receptors in the brain, leading to feelings of happiness and contentment. Many users report a state of relaxation, often accompanied by altered sensory perception. This is a fundamental reason why cannabis is used recreationally, as individuals seek out its mood-enhancing properties to alleviate stress or anxiety.

In contrast, the other options do not accurately reflect the known effects of cannabis abuse. For example, decreased heart rate is not typical; rather, cannabis can lead to an increased heart rate. Similarly, cannabis use does not enhance testosterone levels in males; in fact, it may negatively impact testosterone production. Lastly, while cannabis affects cognitive functions, it generally leads to memory impairment rather than enhanced memory retention. Users often report difficulties with short-term memory while under the influence, which highlights the contrast with the claim of improved memory.
