What is the decrease in reaction time for drivers using marijuana compared to those who text?

The decrease in reaction time for drivers using marijuana compared to those who text is a significant point of discussion regarding the impact of various distractions while driving. Research indicates that texting while driving considerably impairs reaction times, often more severely than marijuana usage. The selection of a 21% decrease in reaction time as the answer reflects findings that show drivers engaged in texting can experience a more pronounced delay in their ability to respond to road situations than those who have consumed marijuana.

Understanding the implications of this data helps in recognizing the extent of distraction from texting, which is frequently more immediate and requires visual and manual engagement with a device, leading to a more substantial decline in reaction times. In contrast, while marijuana also negatively affects driving abilities, the cognitive effects can vary based on individual tolerance and the specific context of consumption. Thus, this information is crucial for promoting safer driving habits and awareness of the dangers posed by texting and mobile device usage on the road.
