Which effect is commonly associated with cannabis use?

• A. Cannabis – altered perception and coordination.
• B. Cannabis – severe respiratory depression with minimal cognitive effect.
• C. Cannabis – instantly cures anxiety and depression.
• D. Cannabis – prevents any impairment in motor skills.

Answer: (A)

Cannabis use commonly affects perception and coordination because the active compound THC alters how the brain processes sensory information and controls movement. This leads to distorted sense of time and space, along with slowed reaction times and impaired motor skills. These effects explain why people often notice difficulties with tasks requiring precise coordination, such as driving. Other statements aren’t as accurate: cannabis doesn’t typically cause severe respiratory depression, doesn’t instantly cure anxiety or depression, and it doesn’t prevent impairment—in fact, it often makes it harder to perform skilled actions.
