Question

which of the following is true about co - use of cannabis and nicotine?
risks of co - use are not backed up by scientific studies.
co - use can impact physical health but does not affect mental health.
co - use keeps users from developing substance use disorder in the long term.
co - use increases health problems compared to only using cannabis or nicotine.

Explanation:

• Analyze each option:
• Option 1: Scientific studies do show risks of co - using cannabis and nicotine, so this is false.
• Option 2: Co - use can affect both physical and mental health (e.g., impact on brain function, mental well - being), so this is false.
• Option 3: Co - use is associated with an increased risk of substance use disorder, not a protective factor, so this is false.
• Option 4: Combining two substances like cannabis and nicotine often leads to more health problems (e.g., respiratory issues from smoking both, increased cardiovascular risks, etc.) than using either alone.

Answer:

D. Co - use increases health problems compared to only using cannabis or nicotine.
